5.1 Regulations prescribing the test procedures for hazardous materials packaging allow for the substitution of non-hazardous fill materials for packaging performance tests with certain limitations prescribed and guidance offered (see 49 CFR 178.602(c)). This regulatory guidance has proven to be flexible enough, in common industry practice, to produce variations in the selection of fill materials for package performance tests sufficient to cause inconsistent and non-repeatable test results. This variation creates significant problems in product liability, packaging selection and regulatory enforcement in this highly regulated industry. Use of this guide should enhance uniformity in test procedures.5.2 Consistent and repeatable test results coupled with clear test fill product descriptions will enhance transportation safety by simplifying packaging selection. This will also increase the general level of confidence that package testing, manufacture, and use are being guided by sound, generally accepted engineering principles. It also aids in clarifying expectations between the packaging industry and the regulatory authorities.5.3 The guide will be used by packaging manufacturers and packaging test labs to create packaging test plans that meet customer needs and conform to the HMR. In addition, for the user of a packaging, certain information about the type and physical characteristics of the material used to test the packaging must be available in the test report and/or notification instruction to allow evaluation of whether a particular packaging was tested with a substitute material appropriate for the hazardous material to be shipped.1.1 The purpose of this guide is to clarify the selection, use, and description criteria of non-hazardous particulate solid substitutes used to replace hazardous materials for the purpose of performance testing packagings. This includes identification of the physical parameters of substitute non-hazardous solid test fill materials that may affect packaging performance and test results and should be considered when selecting and describing a test fill material that conforms to the requirements of the Hazardous Materials Regulations (HMR). This guide is intended for use with package testing procedures for particulate solid materials that have flow characteristics. It is not intended for use with hazardous articles.1.2 This guide provides information to assist packaging users, manufacturers, and performance testing service suppliers regarding the types of physical properties that should be considered when selecting substitute filling substances for the testing, certification and manufacture of packagings under the United Nations packaging protocols (UN Recommendations on the Transport of Dangerous Goods-Model Regulations) as adopted by US DOT in 49 CFR HMR.1.3 This guide provides the suggested minimum information concerning the physical characteristics of the filling substances that should be documented in the certification test report and notification to users to allow for test repeatability and analysis, and to provide guidance to the user of a packaging of pertinent physical differences between potential hazardous lading and the filling substance with which the packaging was tested.1.4 This guide does not purport to address regulatory requirements regarding the compatibility of filling substances with transport packagings. Compatibility requirements must be assessed separately, but it should be noted that under certain national and international dangerous goods regulations, the selection of the filling substances for package performance testing may be prescribed with respect to chemical compatibility requirements.NOTE 1: Under the US HMR determination of packaging compatibility with a particular hazardous fill material is “the responsibility of the person offering the hazardous material for transportation” as prescribed in 49 CFR § 173.24(e).1.5 When testing packaging designs intended for hazardous materials (dangerous goods), the user of this guide shall be trained in accordance with 49 CFR §172.700 and other applicable hazardous materials regulations such as the ICAO Technical Instructions, IMDG Code, other applicable national or international dangerous goods regulations that govern the testing, manufacture and use of packagings authorized for the transportation of dangerous goods, and carrier rules such as the IATA Dangerous Goods Regulations.1.6 The units of measurement are consistent with the HMR.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.1.8 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 It has been shown in many industries that separating information regarding small or dissolved elemental materials in the lubricant from suspended particulate is crucial. In many cases only an overall elemental analysis is provided, which may not capture significant wear or even machinery failure events. Such events are often accompanied by a sudden increase in the production of large particulate, which is suspended in and can be detected in the machinery’s lubricant. This test method specifically targets such particulate, which has historically been difficult to quantify. Users of the technique include numerous military organizations, and maintainers of wind turbines, nuclear power facilities, and offshore rigs.1.1 This automatic wear particle analysis2 test method for in-service lubricants describes using a combination of pore blockage particle counting and energy dispersive X-ray fluorescence (EDXRF) spectrometry for the quantitative determination of solid particle counts larger than four (4) micrometres, and elemental content of suspended particulate of iron (Fe) and copper (Cu) in such lubricants.1.2 This test method provides for the determination of the elemental content of suspended particulate of Fe greater than 4 μm in the range of 6 mg/kg to 223 mg/kg. Suspended particulate of copper greater than 4 μm is determined in the range of 3.5 mg/kg to 92.4 mg/kg in the lubricant. Total particle count greater than 4 μm is determined in the range of 11 495 particles/mL greater than 4 μm to 2 169 500 particles/mL greater than 4 μm in the lubricant.1.3 This test method is applicable to all known in-service lubricants (API Groups I-V) at any stage of degradation.1.4 This test method uses an empirical inter-element correction methodology.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. 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.

5.1 This test method provides a gravimetric measurement of the particulate matter present in a sample of aviation turbine fuel delivered to a laboratory for evaluation. The objective is to minimize these contaminants to avoid filter plugging and other operational problems. Although tolerable levels of particulate contaminants have not yet been established for all points in fuel distribution systems, the total contaminant measurement is normally of most interest.1.1 This test method covers the gravimetric determination by filtration of particulate contaminant in a sample of aviation turbine fuel delivered to a laboratory.1.1.1 The sample is filtered through a test membrane and a control membrane using vacuum. The mass change difference identifies the contaminant level per unit volume.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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. For specific hazard statements, see 4.2, 7.3, 7.5, 11.2, and X1.7.2.

5.1 In the U.S., when 42 Code of Federal Regulations Part 84 (42 CFR 84) was promulgated in 1995, the isoamyl acetate tightness test as described in 30 Code of Federal Regulations Part 11 for certain particulate-removing respirators was removed. These particulate-removing respirators were designed as protection against: (1) fumes of various metals having an air contamination level not less than 0.05 mg/m3, and (2) dusts, fumes, and mists having an air contamination level less than 0.05 mg/m3 or radionuclides. The isoamyl acetate test was removed because particulate respirators had to be modified before they could be tested and there were no other available fit tests suitable to the National Institute for Occupational Safety and Health (NIOSH) for approval testing at the time (1).4 There was a concern that the modified respirators may have had different fitting characteristics from the versions marketed. According to NIOSH, removing this requirement also allowed for further research on the effectiveness of certification fit testing methods (1).5.2 NIOSH conducted benchmark testing of 101 respirator models on the market during 2008 and 2009, using a similar test to that described herein (2). The results were analyzed to develop key test parameters and pass/fail criteria options for a respirator fit capability test for half-facepiece air-purifying particulate respirators (3). According to NIOSH, approximately 30 % of the models tested did not have good fitting characteristics (2). This was also supported by published research (4, 5). This standard establishes a performance requirement called respirator fit capability to assess respirator face-sealing characteristics.5.3 This standard can be used to evaluate all particulate-removing respirators on a population of wearers. A respirator model meeting the fit capability requirement will be capable of fitting the facial sizes and shapes for which it was designed. To achieve this goal, it is necessary for the method to reject poor-fitting respirators, while still passing well-fitting respirators meeting the pass/fail criteria established in this standard. It is thought that this standard will increase the likelihood that respirators meeting this requirement will fit a wide variety of their prospective wearers when properly fit tested, donned, and used.1.1 This standard provides detailed instructions for performing a respirator fit capability test to determine the fit of air-purifying, half-facepiece respirators, which will include both filtering facepiece respirators and elastomeric respirators equipped with any type of particulate filter. The purpose is to increase the probability that available respirators fit a general worker population. The standard provides increased assurance to respirator purchasers and users that respirators that meet the requirement of this standard can be expected to effectively fit persons with various lengths and widths of faces, such as long and narrow or short and wide, when fit tested in the workplace as part of a complete respiratory protection program in accordance with 29 CFR 1910.134.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 It is the responsibility of the investigator to determine whether good laboratory practices (GLP standards—40 CFR, Part 160 of FIFRA) are required and to follow them when appropriate.1.4 This standard does not address specific product performance standards established by regulatory authorities; see 2.2 for details.1.5 This standard does not eliminate the need for every wearer to undergo a personal respirator fit test.1.6 This standard does not guarantee that every respirator wearer will be able to achieve the required fit factor on a particular manufacturer’s single-size or multi-size respirator model. Respirator wearers must always be given the opportunity to try other models or other manufacturers’ respirators.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.1.8 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 is used to demonstrate compliance with state, EPA as well as relevant international regulations for PM emissions from light-duty vehicles.5.1.1 The EPA Tier 3 and CARB LEV III regulations specify FTP and SFTP PM emission standards for light-duty vehicles.1.1 This test method covers a procedure for the gravimetric determination of particulate matter (PM) collected from diluted light duty vehicle exhaust. It is applicable to mass rates from 0.32 to 32 mg/km (0.2 to 20 mg/mile).1.2 Diluted exhaust is passed through pre-weighed filter media which is re-weighed after sampling. The difference in weight is used to determine particulate mass, which is then used with other data to calculate the distance specific emissions.1.3 The particulate materials that are measured using this test method are generated by a vehicle following the PM standard applicable portions of the United States Environmental Protection Agency (EPA) and California Air Resources Board (CARB) driving schedules and test procedures for determining the emissions of light duty vehicles. For other jurisdictions, consult regional regulations for applicability of these test procedures. These test procedures are referenced in Annex A3 of this document.1.4 The primary intent of this test method is to summarize the PM measurement test procedures as defined by the EPA and CARB (40 CFR Parts §1066, §1065, §86.101, and CARB test procedures for hybrid vehicle testing).NOTE 1: Some requirements are generalized from core references for simplicity and to provide guidance for users applying the principals in this standard to regions not governed by EPA and CARB regulation. For specific details, reference the regulated procedures.1.5 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.1.6 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.

5.1 The Hi-Vol sampler is commonly used for the collection of the airborne particulate component of the atmosphere. Some physical and chemical parameters of the collected particulate matter are dependent upon the physical characteristics of the collection system and the choice of filter media. A variety of options available for the Hi-Vol sampler give it broad versatility and allow the user to develop information about the size and quantity of airborne particulate material and, using subsequent chemical analytical techniques, information about the chemical properties of the particulate matter.5.2 This test method presents techniques that when uniformly applied, provide measurements suitable for intersite comparisons.5.3 This test method measures the atmosphere presented to the sampler with good precision, but the actual dust levels in the atmosphere can vary widely from one location to another. This means that sampler location may be of paramount importance, and may impose far greater variability of results than any lack of precision in the method of measurement. In particular, localized dust sources may exert a major influence over a very limited area immediately adjacent to such sources. Examples include unpaved streets, vehicle traffic on roadways with a surface film of dust, building demolition and construction activity, or nearby industrial plants with dust emissions. In some cases, dust levels measured close to such sources may be several times the community wide levels exclusive of such localized effects (see Practice D1357).1.1 This test method provides for sampling a large volume of atmosphere, 1600 m3 to 2400 m3 (55 000 ft3 to 85 000 ft3), by means of a high flow-rate vacuum pump at a rate of 1.13 m3/min to 1.70 m3/min (40 ft3/min to 60 ft3/min) (1-4).21.2 This flow rate allows suspended particles having diameters of less than 100 μm (stokes equivalent diameter) to be collected. However, the collection efficiencies for particles larger than 20 μm decreases with increasing particle size and it varies widely with the angle of the wind with respect to the roof ridge of the sampler shelter and with increasing speed (5). When glass fiber filters are used, particles within the size range of 100 μm to 0.1 μm diameters or less are ordinarily collected.1.3 The upper limit of mass loading will be determined by plugging of the filter medium with sample material, which causes a significant decrease in flow rate (see 6.4). For very dusty atmospheres, shorter sampling periods will be necessary. The minimum amount of particulate matter detectable by this method is 3 mg (95 % confidence level). When the sampler is operated at an average flow rate of 1.70 m3/min (60 ft3/min) for 24 h, this is equivalent to 1 μg/m3 to 2 μg/m3 (3).1.4 The sample that is collected may be subjected to further analyses by a variety of methods for specific constituents.1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered 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.
