5.1 Latex paints, alkyd paints, and primers are used as coatings for walls, wooden trim, and furnishings in occupied buildings. Paint may be applied to large surface areas and may be applied repeatedly during the lifetime of a building. VOCs are emitted from paint after application to surfaces.5.2 Many other types of architectural coatings may be used in large quantities indoors in buildings. In particular, many different types of coatings are used for floors including wood floor stains and finishes and concrete sealers, hardeners, and stains. Two component finishes are often mixed on site and are applied to floors and other surfaces to create a finished surface.5.3 There is a need for standardized procedures for measuring the emissions of VOCs from paint and coating samples that can be reproduced by different laboratories and that can used for the assessment of the acceptability of VOC emissions from paints and coatings that are intended for use indoors in occupied spaces. This practice describes standardized procedures that can be incorporated into test methods used for the purpose of estimating the impacts of cured paints and coatings on indoor air quality. Different procedures are required for the estimation of VOC exposures to workers applying such products.1.1 This practice describes procedures for testing the emissions of volatile organic compounds (VOCs), formaldehyde, and other carbonyl compounds, from alkyd paint, latex paint, primer, and other architectural coating samples using a small-scale environmental chamber test facility.1.2 This practice describes the requirements for the chamber test facility, the small-scale test chamber, the clean air supply system, the environmental controls, the environmental monitoring and data acquisition system, and the chamber air sampling system.1.3 This practice describes procedures for documenting the paint and coating samples and for the handling and storage of these samples including splitting of samples into smaller containers for storage and subsequent testing.1.4 This practice identifies appropriate substrates to be used for the preparation of test specimens of paints and coatings, as well as procedures for preparing substrates for use.1.5 This practice provides detailed procedures for preparing test specimens of paint and coating samples.1.6 This practice generally describes chamber test procedures and chamber air sampling procedures. The details of these procedures are dependent upon the objectives of the test.1.7 This practice does not recommend specific methods for sampling and analysis of VOCs, formaldehyde, and other carbonyl compounds. The appropriate methods are dependent upon the objectives of the test.1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.9 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.1.10 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 practice provides a general procedure for the solvent extraction of volatile and semi-volatile organic compounds from a water matrix. Solvent extraction is used as the initial step in the solvent extraction of organic constituents for the purpose of quantifying extractable organic compounds.4.2 Typical detection limits that can be achieved using micro-extraction techniques with gas chromatography (GC) with flame ionization detector (FID), electron capture detector (ECD), or with a mass spectrometer (GC/MS) range from milligrams per litre (mg/L) to nanograms per litre (ng/L). The detection limit, linear concentration range, and sensitivity of the test method for a specific organic compound will depend upon the sample clean-up, injection volume, solvent to sample ratio, solvent concentration methods used, and the determinative technique employed.4.3 Micro-extraction has the advantage of speed, simple extraction devices, and the use of small amounts of sample and solvents.4.3.1 Selectivity can be improved by the choice of solvent (usually hexane or pentane) or mixed solvents, extraction time and temperature, and ionic strength of the solution.4.3.2 Extraction devices can vary from the sample container itself to commercial devices specifically designed for micro-extraction. See 7.1 and 7.2.4.3.3 A list of chlorinated organic compounds that can be determined by this practice includes both high and low boiling compounds or chemicals (see Table 1).(A) Based on the injection of chlorinated compounds in pentane solution, taking into consideration the 100:1 concentration of a water sample by the microextraction technique.1.1 This practice covers standard procedures for extraction of volatile and semi-volatile organic compounds from water using small volumes of solvents.1.2 The compounds of interest must have a greater solubility in the organic solvent than the water phase.1.3 Not all of the solvents that can be used in micro extraction are addressed in this practice. The applicability of a solvent to extract the compound(s) of interest must be demonstrated before use.1.4 This practice provides sample extracts suitable for any technique amenable to solvent injection such as gas chromatography or high performance liquid chromatography (HPLC).1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use.

This practice covers the standard procedure for determining impurities, stabilizers, and assays of halogenated organic solvents and their admixtures by gas chromatography. It is not the intent of this practice to provide a specific method of gas chromatography, but rather it defines what is required for a user to demonstrate that a method to be used is valid. The use of this practice allows the user to use the most effective technology and demonstrate that the method in use complies with a standard practice and is valid for the analytes involved.1.1 This practice covers the determination of impurities, stabilizers and assay of halogenated organic solvents and their admixtures by gas chromatography.1.2 It is not the intent of this practice to provide a specific method of gas chromatography. The intent of this practice is to define what is required for a user to demonstrate that a method to be used is valid. The reason for this approach, as opposed to stating a method, is that gas chromatography is such a dynamic field that methods are often obsolete by the time they are validated. The use of this practice allows the user to use most effective technology and demonstrate that the method in use complies with a standard practice and is valid for the analysis of halogenated organic solvents and their admixtures.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 Chamber testing is a globally-accepted method for measuring the emissions of VOCs from building materials and products. Chamber emission test data have a variety of uses including identification and labeling of products as low-VOC emitting for improved indoor air quality, manufacturing quality control, and development of new and improved products for reduced VOC emissions.5.2 Currently, an inter-laboratory study (ILS) is the most frequently used method for assessing the bias of a laboratory’s VOC emission test results. An ILS typically relies on a VOC source with an uncharacterized emission rate. Consequently, a large number of participants (Practice E691 recommends 30, with a minimum requirement of six) are needed to produce the data required to calculate a laboratory’s performance relative to the central tendency and distribution of the results for all participants. Due to the participant size requirement and other logistical issues, an ILS involves significant planning and coordination to achieve useful results.5.3 Inter-laboratory studies have often shown significant variations in measured VOC emission rates among participating laboratories for a given source. Variability in the emission rate from the source often is suspected to be a contributing factor, but it is difficult to be certain of the cause. Thus, better characterized sources are needed for evaluating the ability of laboratories to generate VOC emission test results with acceptable bias as discussed in 8.6.5.4 Proficiency tests (PT) for VOC emission testing typically focus on a laboratory’s analytical capabilities. For example, an analytical PT relies on a certified standard prepared by an accredited vendor as a reference. A laboratory analyzes the PT sample without knowledge of its concentration value. Acceptance of the results is judged by the deviation from the known value. Use of reference materials can expand analytical PT schemes to also include the impacts of test sample handling, test specimen preparation, chamber operation, and chamber air sampling.5.5 Laboratories accredited under ISO/IEC 17025 are required to derive uncertainty estimates for their test results. Typically, this is done by developing an uncertainty budget and estimating an expanded uncertainty (ISO/IEC Guide 98, Practice D7440). Reference materials not accredited under ISO/IEC 17025 should still be delivered with documented uncertainty budgets. An uncertainty budget for a VOC emission test combines relevant sources of measurement uncertainty for all steps in the testing process from test specimen preparation through air sample analysis. A more efficient approach to determining the overall bias and precision for a VOC emission test is with repeated testing of a reference material (see ISO/IEC Guide 98, ISO Guide 33). This guide addresses the estimation of bias through comparison of the measured value to the reference material value. The precision is determined through repeated testing of multiple reference materials, ideally from the same production batch (see Practices D6299 and E691).5.6 Other uses of an emissions reference material include verifying quality control emission measurements of manufactured product batches and providing traceability for third party certification.1.1 This guide provides procedures for using a reference material with a known emission rate of a volatile organic compound (VOC) to estimate the bias associated with a VOC emission chamber test.1.2 This guide may be used to assess measurements of VOC emissions conducted in a variety of environmental chambers, such as small-scale chambers, full-scale chambers, emission cells, and micro-scale chambers.1.3 This guide may be used to assess measurements of VOC emissions from a variety of sources including “dry” materials (for example, carpet, floor tile and particleboard) and “wet” materials (for example, paint and cleaning products).1.4 This guide can be used to support quality control efforts by emissions testing laboratories, third party accreditation of testing laboratories participating in emissions testing programs, and quality control efforts by manufacturers of building and other materials.1.5 This guide may be used to support the determination of precision and bias of other commonly used VOC emission standards including Guide D5116, Test Method D6007, ISO 16000-9, ANSI/BIFMA M7.1, and CDPH/EHLB/Standard Method V1.2.1.6 This guide also describes the attributes of a suitable emission reference material and the different methods available to independently determine the reference material’s VOC emission rate.1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.8 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.1.9 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 A high percentage of insoluble, suspended solid material can create pumping, filtering, or grinding difficulties in the off-loading of bulk shipments of OLHW and can contribute to excessive wear on processing equipment. High solids can also decrease the quality and consistency of commingled solutions by decreasing the effectiveness of agitation in storage tanks. These issues are of concern to the recycling industries (solvents, paints, and other materials handled in significant quantities) in addition to those activities that propose to use the waste as a fuel.1.1 This test method covers the determination of the approximate amount of insoluble, suspended solid material in organic liquid hazardous waste (OLHW).1.2 This test method is intended to be used in approximating the amount of insoluble, suspended solids in determining the material-handling characteristics and fuel quality of OLHW.

4.1 This test method determines the volatile organic content of an electrical insulating varnish. It utilizes a procedure where dishes containing a known amount of varnish are baked and the amount of volatile organic compound is measured. Calculations are performed to express this in g/L or lb/gal. This test method is applicable to all types of varnishes. However, waterborne varnishes while baked under the same conditions need to have water content determined and calculations performed in accordance with Practice D3960.4.1.1 During the cure of electrical insulating varnishes some organic material is volatilized. A determination of the amount that is volatilized is useful for estimating the amount of cured varnish on electrical units and volatile organic emissions from a manufacturing facility.1.1 This test method covers the determination of the amount of volatile organic compounds emitted during cure of electrical insulating varnishes.1.2 The values stated in SI units are to be regarded as standard.

5.1 This standard is used in various industries including, but not limited to, agriculture, forestry, energy, horticulture, and geotechnical. Over the years, the use of peat as a fuel has been on the decline for numerous reasons, however it is still being used as a fuel in some parts of the world. Peat typically has high a water content, thus when being used as a fuel, the peat must first be air dried in order to reduce the water content. When the peat it too wet, it doesn’t burn well and much heat is wasted in unnecessary conversion of water to steam and more smoke/soot is created, which can coat a chimney and pose a danger to the end user.5.2 The ash content and percent organic material are important in the following: (1) classifying peat or other organic soil, (2) geotechnical and general classification purposes, and (3) when peats are being evaluated as a fuel. The ash content is one of several parameters used to classify peat as detailed in Classification D4427.NOTE 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors.1.1 These test methods cover the measurement of water (moisture) content, ash content, and organic material in peats and other organic soils, such as organic clays, silts, and mucks. Test Method D2216 provides for determining the water (moisture) content in mineral soils and rock.1.2 This standard has two different ways to determine the water content of the specimen prior to determining the ash content based on the application for which the peat or organic soil is being used. For general classification of peat/organic soils not being used for fuel, the water content is determined using oven drying. For peat/organic soils being used as a fuel, the water content is determined first by air drying followed by oven drying.1.3 There are two Methods, A and B, for determining the ash content and organic material of peat or organic soils. For general classification purposes, Method A is used to determine the water content, ash content, and organic material. When the peat is being used as a fuel, Method B is used to determine the water content, ash content and organic material.1.3.1 Method A—The ash content and organic material of peat or organic soils is determined by igniting the oven-dried specimen as obtained from the water content determination in a furnace at 440 ± 40°C. This method is used for general purposes and should not be used when the peat or organic soils are being used or evaluated for use as a fuel.1.3.2 Method B—The ash content and organic material of peat or organic soils is determined by igniting the air-dried then oven-dried specimen obtained from the water content determination in a furnace at 750 ± 38°C. This method is used when the peat or organic soil is being used as or evaluated for use as a fuel.1.4 Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.1.5 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026.1.5.1 The procedures used to specify how data are collected/recorded or calculated in this standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design.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 The effects of VOC sources on the indoor air quality in buildings have not been well established. One basic requirement that has emerged from indoor air quality studies is the need for well-characterized test data on the emission factors of VOCs from building materials. Standard test method and procedure are a requirement for the comparison of emission factor data from different products.4.2 This practice describes a procedure for using a small environmental test chamber to determine the emission factors of VOCs from wood-based panels over a specified period of time. A pre-screening analysis procedure is also provided to identify the VOCs emitted from the products, to determine the appropriate GC-MS or GC-FID analytical procedure, and to estimate required sampling volume for the subsequent environmental chamber testing.4.3 Test results obtained using this practice provide a basis for comparing the VOC emission characteristics of different wood-based panel products. The emission data can be used to inform manufacturers of the VOC emissions from their products. The data can also be used to identify building materials with reduced VOC emissions over the time interval of the test.4.4 While emission factors determined by using this practice can be used to compare different products, the concentrations measured in the chamber shall not be considered as the resultant concentrations in an actual indoor environment.1.1 The practice measures the volatile organic compounds (VOC), excluding formaldehyde, emitted from manufactured wood-based panels. A pre-screening analysis is used to identify the VOCs emitted from the panel. Emission factors (that is, emission rates per unit surface area) for the VOCs of interest are then determined by measuring the concentrations in a small environmental test chamber containing a specimen. The test chamber is ventilated at a constant air change rate under the standard environmental conditions. For formaldehyde determination, see Test Method D6007.1.2 This practice describes a test method that is specific to the measurement of VOC emissions from newly manufactured individual wood-based panels, such as particleboard, plywood, and oriented strand board (OSB), for the purpose of comparing the emission characteristics of different products under the standard test condition. For general guidance on conducting small environmental chamber tests, see Guide D5116.1.3 VOC concentrations in the environmental test chamber are determined by adsorption on an appropriate single adsorbent tube or multi-adsorbent tube, followed by thermal desorption and combined gas chromatograph/mass spectrometry (GC-MS) or gas chromatograph/flame ionization detection (GC-FID). The air sampling procedure and the analytical method recommended in this practice are generally valid for the identification and quantification of VOCs with saturation vapor pressure between 500 and 0.01 kPa at 25°C, depending on the selection of adsorbent(s).NOTE 1: VOCs being captured by an adsorbent tube depend on the adsorbent(s) and sampling procedure selected (see Practice D6196). The user should have a thorough understanding of the limitations of each adsorbent used. Although canisters can be used to sample VOCs, this standard is limited to sampling VOCs from the chamber air using adsorbent tubes.1.4 The emission factors determined using the above procedure describe the emission characteristics of the specimen under the standard test condition. These data can be used directly to compare the emission characteristics of different products and to estimate the emission rates up to one month after the production. They shall not be used to predict the emission rates over longer periods of time (that is, more than one month) or under different environmental conditions.1.5 Emission data from chamber tests can be used for predicting the impact of wood-based panels on the VOC concentrations in buildings by using an appropriate indoor air quality model, which is beyond the scope of this practice.1.6 The values stated in SI units shall be regarded as the standard (see IEEE/ASTM SI-10).1.7 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.

This specification covers corrosion-resistant coating consisting of an inorganic aluminum particle-filled basecoat and an organic or inorganic topcoat. The basecoat is a water-dilutable slurry containing aluminum particles dispersed in a liquid binder of chromate/phosphate compounds. The organic topcoats consist of polymer resins and dispersed pigments. The inorganic topcoats consist of ceramic oxide pigments dispersed in a liquid binder of chromate/phosphate compounds. These coatings are applied by conventional dip/spin, dip/drain, or spray methods. The coating systems defined by this specification can be applied to ferrous alloy steels, aluminum, and ferritic and austenitic stainless steels. The inorganic aluminum particle-filled basecoat and the subsequent topcoats are classified into three groups, with subsequent subgroups. Materials shall be tested and the individual grades shall conform to specified values of appearance, adhesion, corrosion, thread-fit, weathering, coating thickness, and humidity.1.1 This specification covers the basic requirements for a corrosion-resistant coating consisting of an inorganic aluminum particle-filled basecoat and an organic or inorganic topcoat, depending on the specific requirements.1.2 The coating may be specified with basecoat only, or with the top coated with compatible organic polymer or inorganic topcoats, depending on the specific requirements.1.3 The basecoat is a water-dilutable slurry containing aluminum particles dispersed in a liquid binder of chromate/phosphate compounds.1.4 The organic topcoats consist of polymer resins and dispersed pigments and are for service where temperatures do not exceed 230 °C (450 °F).1.5 The inorganic topcoats consist of ceramic oxide pigments dispersed in a liquid binder of chromate/phosphate compounds and are for service where temperatures do not exceed 645 °C (1200 °F).1.6 These coatings are applied by conventional dip/spin, dip/drain, or spray methods.1.7 The coating process does not normally induce hydrogen embrittlement, provided that the parts to be coated have not been subjected to an acid cleaner or pretreatment (see Note 1).NOTE 1: Although this coating material contains water, it has a relatively low susceptibility to inducing hydrogen embrittlement in steel parts of tensile strengths equal to or greater than 1000 MPa (approximately RC31). Normal precautions for preparing, descaling, and cleaning steels of these tensile strengths must be observed. An initial stress relief treatment should be considered prior to any chemical treatment or cleaning operation. Acids or other treatments that evolve hydrogen should be avoided. Mechanical cleaning methods may be considered. Some steels are more susceptible to hydrogen embrittlement than others and may also require hydrogen embrittlement relief baking after cleaning but before coating. Since no process can completely guarantee freedom from embrittlement, careful consideration must be given to the entire coating process and the specific steel alloy employed.1.8 The coating systems defined by this specification can be applied to ferrous alloy steels, aluminum, and ferritic and austenitic stainless steels.1.9 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.10 The following safety hazards caveat pertains only to the test methods portion, Section 6, of this specification: 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.1.11 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.
