5.1 Attachment of overspray particles to vehicles and other surfaces not intended to be coated can result in property damage and insurance claims. Dry fall coatings are formulated such that overspray particles dry as they move through the air, and before they land on horizontal surfaces. These particles can then be brushed off, vacuumed or washed from the surfaces with no damage. This practice can be used to evaluate the dry fall properties of coatings prior to large scale use. The practice can also be used to evaluate whether the coating(s) possess the same dry fall properties when the fallout collects on surfaces with an elevated temperature.1.1 This practice covers a procedure for qualitatively evaluating the dry fall properties of coatings. The establishment of the test environment and the evaluation procedures are described.1.2 This practice uses panels containing an automotive finish since these types of surfaces are often the primary concern relating to overspray damage. Panels coated with other systems may be used as collection surfaces when they are deemed to be more representative.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 This test method is applicable for testing GCCMs in the cured state. This determines the initial and final breaking load to determine the initial and final tensile strength of the GCCM. It is used with a constant rate of extension type tensile testing machine.4.2 GCCMs are composites, and the cured cementitious material typically has a lower tensile strength to the geosynthetic layer(s). When testing the tensile strength of a cured GCCM, multiple cracks will typically form in the cementitious material, transferring loads to the reinforcing fibers (or linking elements) before the ultimate tensile strength of the GCCM is reached. In certain applications, engineers need to know the initial tensile strength of the GCCM, which is when the cementitious material first breaks and the material’s rigidity is reduced, not just the final tensile strength (ultimate strength), which is governed primarily by the geosynthetic layer(s).4.3 In service, the top layer of geosynthetic in a GCCM is particularly exposed to degradation from UV exposure and abrasion, especially in erosion control applications such as for channel lining with high levels of sedimentation in water flow. It is important that reported values take account of the effects of environmental degradation where this has a significant effect on in-service performance. It is therefore also necessary to test the initial and final tensile strength of the GCCM when the top layer has been removed to provide an indication of long-term GCCM tensile performance.1.1 The purpose of the proposed test method is to determine the tensile strength of cured/hydrated GCCM materials to include reporting the initial tensile strength (first crack in the cementitious layer) and final tensile strength for GCCMs as supplied and in a weathered state with the geosynthetic top layer(s) removed.1.2 As a performance test, this method will be used relatively infrequently and to test large lots of material. This test is not intended for routine quality control testing of GCCMs.1.3 The values in SI units are to be regarded as the standard. Values in inch-pound units are in parentheses for information.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 This standard provides a practice for RIQR evaluations of film and non-film imaging systems when exposed through an absorber material. Three alternate data evaluation methods are provided in Section 9. Determining RIQR requires the comparison of at least two radiographs or radiographic processes whereby the relative degree of image quality difference may be determined using the EPS plaque arrangement of Fig. 1 as a relative image quality indicator (RIQI). In conjunction with the RIQI, a specified radiographic technique or method must be established and carefully controlled for each radiographic process. This practice is designed to allow the determination of subtle changes in EPS that may arise to radiographic imaging system performance levels resultant from process improvements/changes or change of equipment attributes. This practice does not address relative unsharpness of a radiographic imaging system as provided in Practice E2002. The common element with any relative comparison is the use of the same RIQI arrangement for both processes under evaluation.4.2 In addition to the standard evaluation method described in Section 9, there may be other techniques/methods in which the basic RIQR arrangement of Fig. 1 might be utilized to perform specialized assessments of relative image quality performance. For example, other radiographic variables can be altered to facilitate evaluations provided these differences are known and documented for both processes. Where multiple radiographic process variables are evaluated, it is incumbent upon the user of this practice to control those normal process attributes to the degree suitable for the application. Specialized RIQR techniques may also be useful with micro focus X-ray, isotope sources of radiation or with the use of non-film radiographic imaging systems. RIQR may also be useful in evaluating imaging systems with alternate materials (RIQI and base plate) such as plastic, copper-nickel, or aluminum. When using any of these specialized applications, the specific method or techniques used shall be as specified and approved by the cognizant engineering organization.1.1 This standard covers a practice whereby industrial radiographic imaging systems or techniques may be comparatively assessed using the concept of relative image quality response (RIQR). Changes within a radiographic technique such as film/detector types, distances, or filtering/collimation can be comparatively assessed using this standard. The RIQR method presented within this practice is based upon the use of equivalent penetrameter sensitivity (EPS) described within Practice E1025 and subsection 5.4 of this practice. Fig. 1 illustrates a relative image quality indicator (RIQI) that has four different plaque thicknesses (0.38 mm, 0.25 mm, 0.20 mm, and 0.13 mm (0.015 in., 0.010 in., 0.008 in., and 0.005 in.)) sequentially positioned (from top to bottom) on an absorber plate of a specified material and thickness. The four plaques contain a total of 14 different arrays of penetrameter-type hole sizes designed to render varied conditions of threshold visibility when exposed to the appropriate radiation. Each “EPS” array consists of 30 identical holes; thus, providing the user with a quantity of threshold sensitivity levels suitable for relative image qualitative response comparisons. There are two standard materials (steel and plastic) specified herein for the RIQI and absorber. For special applications the user may design a non-standard RIQI-absorber configuration; however the RIQI configuration shall be controlled by a drawing similar to Fig. 1. Use of a non-standard RIQI-absorber configuration shall be described in the user’s written technique and approved by the CEO.1.2 This practice is not intended to qualify the performance of a specific radiographic technique nor for assurance that a radiographic technique will detect specific discontinuities in a specimen undergoing radiographic examination.1.3 This practice is not intended to be used to classify or derive performance classification categories for radiographic imaging systems. For example, performance classifications of radiographic film systems may be found within Test Method E1815, and manufacturer characterization of computed radiography (CR) systems may be found in Practice E2446. However, the RIQI and absorber described in this practice are used by Practice E2446 for manufacturer characterization of computed radiography (CR) systems and by Practice E2445 to evaluate performance and to monitor long term stability of CR systems.1.4 These tests are for applications below 4 MeV. When a gamma source or other high energy source is used, these tests may still be used to characterize the system, but may need a modification of the absorber thickness to adjust the available RIQR range as agreed between the user and cognizant engineering organization (CEO). For high-energy X-ray applications (4 MV to 25 MV), Test Method E1735 provides a similar RIQR standard practice.1.5 The values stated in SI are to be regarded as the standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 Numerous ASTM test methods and practices (for example: Test Methods D5259 and D5392, and Practices D6974 and E2563) report colony counts as their measured parameter.4.2 These practices provide a uniform set of counting, calculating, and reporting procedures for ASTM test methods in microbiology.  SectionA—Counting Colonies on Membrane Filters 6B—Counting Colonies on Pour Plates 7C—Counting Colonies on Spread Plates 84.3 The counting rules provide a best attainable estimate of microorganisms in the sample, since the samples cannot be held and reanalyzed at a later date.1.1 These practices cover recommended procedures for counting colonies and reporting colony-forming units (CFU) on membrane filters (MF) and standard pour and spread plates.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 Upper limits for the formaldehyde emission rates have been established for wood panel building products made with urea-formaldehyde adhesives and permanently installed in homes or used as components in kitchen cabinets and similar industrial products. This test method is intended for use in conjunction with the test method referenced by HUD 24 for manufactured housing and by Minnesota Statutes for housing units and building materials. This method may also be used for monitoring products for compliance to the California Air Resources Board (CARB) regulation for composite wood products and the Environmental Protection Agency Formaldehyde Emission Standards for Composite Wood Products, EPA TSCA Title VI 40 CFR Section 770. This test method provides a means of testing smaller samples and reduces the time required for testing.4.2 Formaldehyde concentration levels obtained by this small-scale method may differ from expected in full-scale indoor environments. Variations in product loading, temperature, relative humidity, and air exchange will affect formaldehyde emission rates and thus likely indoor air formaldehyde concentrations.4.3 This test method requires the use of a chamber of 0.02 to 1 m3 in volume to evaluate the formaldehyde concentration in air using the following controlled conditions:4.3.1 Conditioning of specimens prior to testing,4.3.2 Exposed surface area of the specimens in the test chamber,4.3.3 Test chamber temperature and relative humidity,4.3.4 The Q/A ratio, and4.3.5 Air circulation within the chamber.1.1 This test method measures the formaldehyde concentrations in air emitted by wood product test specimens under defined test conditions of temperature and relative humidity. Results obtained from this small-scale chamber test method are intended to be comparable to results obtained from testing larger product samples by the large chamber test method for wood products, Test Method E1333. The results may be correlated to values obtained from Test Method E1333. The quantity of formaldehyde in an air sample from the small chamber is determined by a modification of NIOSH 3500 chromotropic acid test procedure. As with Test Method E1333, other analytical procedures may be used to determine the quantity of formaldehyde in the air sample provided that such methods give results comparable to those obtained by using the chromotropic acid procedure. However, the test results and test report must be properly qualified and the analytical procedure employed must be accurately described.1.2 The wood-based panel products to be tested by this test method are characteristically used for different applications and are tested at different relative amounts or loading ratios to reflect different applications. This is a test method that specifies testing at various loading ratios for different product types. However, the test results and test report must be properly qualified and must specify the make-up air flow, sample surface area, and chamber volume.1.3 Ideal candidates for small-scale chamber testing are products relatively homogeneous in their formaldehyde release characteristics. Still, product inhomogeneities must be considered when selecting and preparing samples for small-scale chamber testing.1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This test method can be used to determine anti-wear properties and coefficient of friction of greases in order to prevent “fretting” wear under linear oscillation with associated low strokes and high Hertzian contact pressures at selected temperatures and loads specified for use in applications in which induced, high-speed vibrational motions are present for extended periods of time. It has found application as a screening test for grease lubricants used in ball and roller bearings, roller or ball screw (spindle) drives or side shaft systems (Tripode or Rzeppa type) for example, so-called constant velocity (CV) joints. Users of this test method should determine whether results correlate with field performance or other applications.1.1 This test method covers a procedure for determining the lubricating action of greases in order to prevent “fretting” wear under linear oscillation with associated low strokes and high Hertzian contact pressures under high-frequency linear-oscillation motion using the SRV test machine. By performing additional, nonmandatory extreme-pressure tests in accordance with Test Method D5706, the test grease should be shown to be able to withstand a Hertzian contact pressure of at least 2200 MPa without adhesive failure.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 Uses—This practice is intended for use by federal agencies, and environmental professionals in order to facilitate ECP efforts. It is also intended for use by preparers and reviewers of environmental condition of property maps and ECP reports used to support CERFA uncontaminated property identifications and property suitable for transfer by lease or by deed. GSA regulations addressing the disposal of federal property (41 CFR §105-72), require the landholding agency to assert either that (a) there is no evidence of hazardous substance activity, or (b) there is evidence of hazardous substance activity that occurred on the property. If there is evidence that hazardous substance activity occurred on the property, the landholding agency has a “due diligence” obligation to provide detailed, accurate information on all “reportable quantities” of hazardous substances stored, released, or disposed of on property that it reports to GSA for disposal. The specific substances that must be reported under CERCLA and their reporting limits are described in 40 CFR §302.4 and 40 CFR §373. If the landholding agency discloses that hazardous substance activity took place on the property, then the landholding agency must assert whether or not all required remedial action necessary to protect human health and the environment has been taken with respect to those hazardous substances.4.1.1 The ECP reports prepared in accordance with this practice may be used to achieve compliance with the federal Management Regulations, Real Property Disposal rules codified in 41 CFR §102-75.4.2 Clarifications on Use: 4.2.1 Use Not Limited to CERCLA—This practice is designed to assist the user in developing information about the environmental condition of a property and as such has utility for a wide range of persons, including those who may have no actual or potential CERCLA liability (see 40 CFR §373, 41 CFR §102-75 and Section 208 of the Federal Land Policy and Management Act, Public Law 94-579).4.2.2 Residential Tenants/Purchasers and Others—No implication is intended that it is currently customary practice for residential tenants of multifamily residential buildings, tenants of single-family homes or other residential real estate, or purchasers of dwellings for one's own residential use, to conduct an ECP in connection with these transactions. Thus, these transactions are not included in the term commercial real estate transactions. Thus, although such property may be included within the scope of an ECP, their occupants shall not be treated as key site personnel with regard to the housing occupied for the purpose of conducting an ECP.4.2.3 Site-Specific—This practice is site-specific in that it relates to assessment of environmental conditions of federal real property. Consequently, this practice does not address many additional issues raised in transactions such as purchases of business entities; or interests therein, or of their assets, that may well involve environmental liabilities pertaining to properties previously owned or operated or other off-site environmental liabilities.4.3 Related Practices—See Practices E1527 and E2247.4.4 Principles—The following principles are an integral part of this practice and all related practices and are intended to be referred to in resolving any ambiguity or exercising such discretion as is accorded the user or environmental professional in performing an ECP or in judging whether a user or environmental professional has conducted appropriate inquiry or has otherwise conducted an adequate ECP.4.4.1 Uncertainty Not Eliminated—No ECP can wholly eliminate uncertainty regarding the potential for recognized environmental conditions in connection with a property. Performance of this practice is intended to reduce uncertainty regarding the potential for recognized environmental conditions in connection with a property to the minimum practicable level, but not eliminate such uncertainty altogether, as well as to recognize reasonable limits of time and cost for property information.4.4.2 Level of Inquiry is Variable—Not every federal property will warrant the same level of ECP effort. Consistent with good practice, the appropriate level of ECP will be guided by the type of property subject to ECP and the information developed in its conduct.4.4.3 Comparison with Subsequent Inquiry—It should not be concluded or assumed that an inquiry was not an appropriate inquiry merely because the inquiry did not identify recognized environmental conditions in connection with a property. The ECPs must be evaluated based on the reasonableness of judgments made at the time and under the circumstances in which they were made. Subsequent ECPs should not be considered valid standards to judge the appropriateness of any prior ECP based on hindsight, new information, use of developing technology or analytical techniques, or other factors.4.5 Continued Viability of Environmental Baseline Survey—An ECP meeting or exceeding this practice and completed less than 180 days prior to the date of a subsequent use is presumed to be valid for that use. An ECP not meeting or exceeding this practice or completed more than 180 days previously may be used to the extent allowed by 4.6 – 4.6.5.4.6 Prior ECP Usage—This practice recognizes that ECPs performed in accordance with this practice or otherwise containing information which was reasonably accurate at the time prepared will include information that subsequent users may want to use to avoid undertaking duplicative ECP procedures. Therefore, this practice describes procedures to be followed to assist users in determining the appropriateness of using information in ECPs performed previously. The system of prior ECP usage is based on the following principles that should be adhered to in addition to the specific procedures set forth elsewhere in this practice:4.6.1 Use of Prior Information—Subject to 4.6.4, users and environmental professionals may use information in prior ECPs provided such information was generated as a result of procedures that meet or exceed the requirements of this practice or accurately state the limitations of the information presented. When using information from an ECP which, as a whole, fails to meet or exceed the requirements of this practice, the use shall be limited to those portions of the ECP which, based upon the limitations and methodology of the ECP report, the environmental professional finds to be reasonably accurate.NOTE 3: Earlier versions of this practice required the review and analysis of a significantly smaller set of records.4.6.2 Prior ECP Meets or Exceeds—Subject to 4.6.4, a prior ECP may be used in its entirety, without regard to the specific procedures set forth in these practices if, in the reasonable judgment of the user, the prior ECP meets or exceeds the requirements of this practice and the conditions at the property likely to affect environmental condition of property area types in connection with the property are not likely to have changed materially since the prior ECP was conducted. In making this judgment, the user should consider the type of property subject to the ECP and the conditions in the area surrounding the property.4.6.3 Current Investigation—Except as specifically provided in 4.6.2, prior ECPs should not be used without current investigation of conditions likely to affect the environmental condition of property in connection with the property that may have changed materially since the prior ECP was conducted. For an ECP to be consistent with this practice, a new visual inspection, interviews, an update of the records review, and other appropriate activities may have to be performed.4.6.4 Actual Knowledge Exception—If the user or environmental professional(s) conducting an ECP has actual knowledge that the information being used from a prior ECP is not accurate or if it is obvious, based on other information obtained by means of the ECP or known to the person conducting the ECP, that the information being used is not accurate, such information from a prior ECP may not be used.4.6.5 Contractual Issues Regarding Prior ECP Usage—The contractual and legal obligations between prior and subsequent users of ECPs or between environmental professionals who conducted prior ECPs and those who would like to use such prior ECPs are beyond the scope of this practice.1.1 Purpose—The purpose of this practice is to define good commercial and customary practice in the United States for assessing the environmental condition of property (ECP) of federal real property. This practice applies to property under consideration for lease, excess and surplus property at closing and realigning military installations, claims reverting to federal ownership such as abandoned mines, and other federally-owned property. The steps in this practice are conducted to fulfill certain requirements of the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA) section 120(h), as amended by the Community Environmental Response Facilitation Act of 1992 (CERFA) and the federal real property disposal regulations codified in 41 CFR Subpart C (41 CFR 102-75). As such, this practice is intended to help a user to gather and analyze data and information in order to classify property into the applicable environmental condition of property area types (in accordance with the ASTM D5746, Standard Classification of Environmental Condition of Property Area Types, (see Appendix X1). Once documented, the ECP report is used to support Findings of Suitability to Transfer (FOSTs), Findings of Suitability to Lease (FOSLs), or uncontaminated property determinations, or a combination thereof, pursuant to the requirements of CERFA and CERCLA § 120(h). Users of this practice should note that it does not address (except where explicitly noted) requirements for appropriate and timely regulatory consultation or concurrence, or both, during the conduct of the ECP or during the identification and use of the standard environmental condition of property area types.1.1.1 Environmental Condition of Property—In accordance with the federal landholding agency policies and General Services Administration’s (GSA) federal real property management regulations, an ECP will be prepared or evaluated for its usefulness (and updated if necessary) for any federally-owned property to be transferred by deed or leased. The ECP will be based on existing environmental information related to storage, release, treatment, or disposal of hazardous substances, munitions, or petroleum products on the property to determine or discover the obviousness of the presence or likely presence of a release or threatened release of any hazardous substance or petroleum product. In certain cases, additional data, including sampling, if appropriate under the circumstances, may be needed in the ECP to support the FOST or FOSL. A previously conducted ECP may be updated as necessary and used for making a FOST or FOSL. An ECP also may help to satisfy other environmental requirements (for example, to satisfy the requirements of CERFA or to facilitate the preparation of environmental condition reports). In addition, the ECP provides a useful reference document and assists in compliance with hazard abatement policies related to asbestos and lead-based paint. The ECP process consists of discrete steps. This practice principally addresses ECP-related information gathering and analysis.1.1.1.1 Discussion—Prior versions of this practice referred to environmental baseline surveys (EBS). The 2018 Department of Defense 4165.66M Base Redevelopment and Realignment Manual changed the focus to ECP. Appendix 3 of DODM 4165.66M provides direction on the preparation of FOST and FOSL documentation. Section C2.4.2.3 of DODM 4165.66M provides direction for Department of Defense property proposed for disposal and redevelopment.1.1.2 CERCLA Section 120(h) Requirements—This practice is intended to assist with the identification of federal real property and DoD installation areas subject to the notification and covenant requirements of CERCLA § 120(h) relating to the deed transfer of contaminated federal real property (42 USC 9601 et seq.), (see Appendix X2). Examples of other federal landholding agencies that must comply with CERCLA §120(h) requirements include the Bureau of Land Management, the Federal Aviation Administration, and U.S. Forest Service.1.1.3 CERFA Requirements—This practice provides information to partially fulfill the identification requirements of CERFA [Pub. L. 102-426, 106 Stat. 2174], which amended CERCLA. Property classified as area Type 1, in accordance with Classification D5746 is eligible for reporting as “uncontaminated” under the provisions of CERFA and the Federal Management Regulations, Real Property Disposal rules codified in 41 CFR 102-75. Additionally, certain property classified as area Type 2, where evidence indicates that storage occurred for less than one year, may also be identified as uncontaminated. At installations and federal property listed on the National Priorities List, Environmental Protection Agency (EPA) concurrence must be obtained for the property to be considered “uncontaminated” and therefore transferable under CERCLA § 120(h)(4). The EPA has stated that there may be instances in which it would be appropriate to concur with the federal landholding agency that certain property can be identified as uncontaminated under CERCLA § 120(h)(4) although some limited quantity of hazardous substances or petroleum products have been stored, released, or disposed of on the property (see EPA Office of Enforcement and Compliance Assurance, May 2019). If the information available indicates that the storage, release, or disposal was associated with activities that would not be expected to pose a threat to human health or the environment (for example, housing areas, petroleum-stained pavement areas, and areas having undergone routine application of pesticides), such property should be eligible for expeditious reuse.NOTE 1: Confirmed releases of emerging chemicals of environmental concern may require additional consideration (see Office of the Undersecretary of Defense. Policy Memorandum for Clarifications and Upcoming Changes to Department of Defense Instruction 4715.18 in Response to Department of Defense Office of Inspector General Findings, April 2022).1.1.4 Petroleum Products—Petroleum products and their derivatives are included within the scope of this practice. Areas on which petroleum products or their derivatives were stored for one year or more, known to have been released or disposed of [CERCLA§ 120(h)(4)] are not eligible to be reported as “uncontaminated property” under CERFA.1.1.5 Other Federal, State, and Local Environmental Laws—This practice does not address requirements of any federal, state, or local laws other than the applicable provisions of CERCLA identified in 1.1.2 and 1.1.3. These applicable or relevant and appropriate requirements (ARARs) may have a bearing upon the ultimate disposition of the federal property. Users are cautioned that federal, state, and local laws may impose additional ECP or other environmental assessment obligations that are beyond the scope of this practice. Users should also be aware that there are likely to be other legal obligations with regard to hazardous substances or petroleum products discovered on property that are not addressed in this practice and that may pose risks of civil or criminal sanctions, or both, for noncompliance.1.1.6 Other Federal, State, and Local Real Property and Natural and Cultural Resources Laws—This practice does not address requirements of any federal, state or local real property or natural and cultural resources laws. Users are cautioned that numerous federal, state, and local laws may impose additional environmental and other legal requirements that must be satisfied prior to deed transfer of property that are beyond the scope of this practice.NOTE 2: The General Services Administration’s Excess Real Property Due Diligence Checklist for Federal Landholding Agency Customers, November 2017, provides additional detail on federal ARARs.1.1.7 Non-Federal Property—This standard may also be used by state and local agencies to assess the environmental condition of non-federal property.1.2 Objectives—Objectives guiding the development of this practice are (1) to synthesize and put in writing a standard practice for conducting a high quality ECP, (2) to facilitate the development of high quality, standardized environmental condition of property maps to be included in an ECP that can be used to support FOSTs, FOSLs, and other applicable environmental condition reports, (3) to facilitate the use of the standard classification of environmental condition of property area types (see Classification D5746), (4) to facilitate the development of a standard guide for preparing and updating ECP reports, and (5) comply with the Federal Real Property Disposal regulations codified in 41 CFR 102-75.1.3 Limitations—Users of this practice should note that, while many of the elements of an ECP are performed in a manner consistent with other “due diligence” functions, an ECP is not prepared to satisfy a purchaser of real property’s duty to conduct “all appropriate inquiries”, as defined in 40 CFR 312, to establish an “innocent landowner defense” to CERCLA § 107 liability. Any such use of any ECP by any party is outside the control of the federal agencies and beyond the scope of any ECP. No warranties or representations are made by any federal agency, its employees, or contractors that any ECP report satisfies any such requirement for any party.1.4 Organization of This Practice—This practice has 15 sections. Section 1 is the scope. Section 2 identifies referenced documents. Section 3, Terminology, includes definitions of terms not unique to this practice, descriptions of terms unique to this practice, and acronyms and abbreviations.

6.1 SPF insulation is applied and formed onsite, which creates unique challenges for measuring product emissions. This test method provides a way to measure post-application chemical emissions from SPF insulation.6.2 This test method can be used to identify compounds that emit from SPF insulation products, and the emission factors may be used to compare emissions at the specified sampling times and test conditions.6.3 Emission data may be used in product development, manufacturing quality control and comparison of field samples.6.4 This test method is used to determine chemical emissions from freshly applied SPF insulation samples. The utility of this test method for investigation of odors in building scale environments has not been demonstrated at this time.1.1 This test method is used to identify and to measure the emissions of volatile organic compounds (VOCs) emitted from samples of cured spray polyurethane foam (SPF) insulation using micro-scale environmental test chambers combined with specific air sampling and analytical methods for VOCs.1.2 Specimens prepared from product samples are maintained at specified conditions of temperature, humidity, airflow rate, and elapsed time in micro-scale chambers that are described in Practice D7706. Air samples are collected periodically at the chamber exhaust at the flow rate of the micro-scale chambers.1.2.1 Samples for formaldehyde and other low-molecular weight carbonyl compounds are collected on treated silica gel cartridges and are analyzed by high performance liquid chromatography (HPLC) as described in Test Method D5197 and ISO 16000-3.1.2.2 Samples for other VOCs are collected on multi-sorbent samplers and are analyzed by thermal-desorption gas chromatography / mass spectrometry (TD-GC/MS) as described in U.S. EPA Compendium Method TO-17 and ISO 16000-6.1.3 This test method is intended specifically for SPF insulation products. Compatible product types include two component, high pressure and two-component, low pressure formulations of open-cell and closed-cell SPF insulation.1.4 VOCs that can be sampled and analyzed by this test method generally include organic blowing agents such as 1,1,1,3,3-pentafluoropropane, formaldehyde and other carbonyl compounds, residual solvents, and some amine catalysts. Emissions of some organic flame retardants can be measured after 24 h with this method, such as tris (chloroisopropyl) phosphate (TCPP).1.5 This test method does not cover the sampling and analysis of methylene diphenyl diisocyanate (MDI) or other isocyanates.1.6 Area-specific and mass-specific emission rates are quantified at the elapsed times and chamber conditions as specified in 13.2 and 13.3 of this test method.1.7 This test method is used to identify emitted compounds and to estimate their emission factors at specific times. The emission factors are based on specified conditions, therefore, use of the data to predict emissions in other environments may not be appropriate and is beyond the scope of this test method. The results may not be representative of other test conditions or comparable with other test methods.1.8 This test method is primarily intended for freshly applied, SPF insulation samples that are sprayed and packaged as described in Practice D7859. The measurement of emissions during spray application and within the first hour following application is outside of the scope of this test method.1.9 This test method can also be used to measure the emissions from SPF insulation samples that are collected from building sites where the insulation has already been applied. Potential uses of such measurements include investigations of odor complaints after product application. However, the specific details of odor investigations and other indoor air quality (IAQ) investigations are outside of the scope of this test method.1.10 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.11 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.12 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 The gasket factors are a function of leak rate; therefore, this practice generates curves. Constants for use in the ASME Boiler and Pressure Vessel Code, Section VIII, Appendix 2 code calculations are selected from these data. Specific m and y values can be selected based on a maximum desired leak rate or derived from these data as described in this procedure. This practice addresses the influence of leak rate and gasket thickness on a gasket’s ability to provide a seal initially and in operation. This practice is performed at room temperature; therefore, this practice does not account for all conditions, such as high temperature or thermal cycling or both, that bolted flange connections may be subject to in field application.4.2 This practice determines two general characteristics that are specific to the ASME design criteria. Caution should be exercised when comparing yield and maintenance factors between gasket materials, and it is recommended that the m and y curves be compared. Selecting a gasket material for use in an application should not be based exclusively on these two general characteristics. Gasket material selection for a given application should consider additional information not described in this practice, which includes, but is not limited to, chemical resistance, thermal resistance, creep relaxation, compressibility, and accommodation of thermal cycling.4.3 This practice builds upon work conducted in the Fluid Sealing Association (FSA G 605:11). The associated round robin data is provided for reference in Tables 1-4.(A) BDL = below detection limit.(A) BDL = below detection limit.1.1 This practice will establish criteria for determining loading constants that are referenced in the American Society of Mechanical Engineers (ASME) pressure vessel design (Boiler and Pressure Vessel Code, Section VIII, Divs. 1 and 2). These constants are specific to this design criterion for metallic, semi-metallic, and nonmetallic gaskets.1.2 Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 This test method estimates the resistance of greases to water washout from ball bearings under conditions of the test. No correlation with field service has been established.1.1 This test method covers the evaluation of the resistance of a lubricating grease to washout by water from a bearing, when tested at 38 °C and 79 °C (100 °F and 175 °F) under the prescribed laboratory conditions. It is not to be considered the equivalent of service evaluation tests. Precision and bias was determined using grease ranging from NLGI 3 to 0 grades in the research report (see Section 10).1.2 This test method may not be suitable for some greases containing highly volatile components. This test method does not attempt to account for sample evaporation. It is the user's responsibility to determine if evaporation of the sample is a significant contributor to mass loss at the required drying temperature.1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see 6.3.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This in vivo procedure is designed to test the ability of hygienic handwash or handrub agents to eliminate selected types of bacteria from experimentally contaminated skin of the hands of adult subjects. Since the two thumbpads and all eight fingerpads can be used in any given test, it allows for the incorporation of an input control (two), control for viable bacteria remaining after the inoculum has been allowed to dry (two), bacteria eliminated after treatment with a control or reference solution (two), and up to four replicates to assess the bacteria-eliminating efficiency of the product under test. No more than 100 µL of the test bacterial suspension is required to complete one test. The results of testing with this test method may form the basis for confirmatory tests using a suitable whole-hand test protocol, such as Test Method E1174.5.2 Whereas this test method relates to testing with bacteria, it can be readily adapted to work with protozoa and bacteriophages. Similar methods for work with fungi (Test Method E2613) and viruses of human origin (Test Method E1838) are already ASTM standards.5.3 Potentially infectious microorganisms left on hands after washing can be reduced further by drying the washed hands with paper, cloth, or warm air (7). A step for the drying of fingerpads after exposure to the control or test solution, therefore, has not been included to avoid bacterial removal by the drying process itself.5.4 This test method is not meant for use with surgical hand scrubs (Test Method E1115) or preoperative skin preps (Test Method E1173).5.5 The level of contamination with viable bacteria on each fingerpad after the drying of the inoculum should be five- to ten-fold higher than the product performance criterion required. For example, the titer in the dried inoculum on each fingerpad should be about 105 colony forming units of the test bacterium when a >104 reduction is required under the conditions of this test method.1.1 This test method is designed to determine the activity of hygienic handwash and handrub (4) agents against transient bacterial flora on hands and is not meant for use with surgical hand scrubs or preoperative skin preps.1.2 Performance of this procedure requires the knowledge of regulations pertaining to the protection of human subjects.31.3 The test method should be performed by persons with training in microbiology in facilities designed and equipped for work with infectious agents at biosafety level 2 (5).1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
