NOTE For general background of the rain simulation, see Annex A.

This document describes the methods that are available to perform a spectral analysis of a pavement surface profile. It specifies a method for performing spatial frequency analysis (or texture wavelength analysis) of two-dimensional surface profiles that describe the pavement texture amplitude as a function of the distance along a straight or curved trajectory over the pavement. It also details an alternative (non-preferred) method to obtain these spectra: a) constant-percentage bandwidth obtained by digital filtering (normative method); b) constant narrow bandwidth frequency analysis by means of discrete Fourier transform (DFT), followed by a transformation of the narrow-band spectrum to an octave- or one-third-octave-band spectrum (informative). The result of the frequency analysis will be a spatial frequency (or texture wavelength) spectrum in constant-percentage bandwidth bands of octave or one-third-octave bandwidth. The objective of this document is to standardize the spectral characterization of pavement surface profiles. This objective is pursued by providing a detailed description of the analysis methods and related requirements for those who are involved in pavement characterization but are not familiar with general principles of frequency analysis of random signals. These methods and requirements are generally applicable to all types of random signals; however, they are elaborated in this document for their use in pavement surface profile analysis. NOTE The spectral analysis as specified in this document cannot express all characteristics of the surface profile under study. In particular, the effects of asymmetry of the profile, e.g. the difference of certain functional qualities for “positive” and “negative” profiles cannot be expressed by the power spectral density, as it disregards any asymmetry of the signal (see Annex B).

This document specifies a volumetric method for the determination of silver on a material considered homogeneous. The silver content of the sample lies preferably between (100 and 999,0) parts per thousand (‰) by mass. Fineness above 999,0 ‰ can be determined using a spectroscopy method by difference (e.g. ISO 15096).
This method is intended to be used as the reference method for the determination of fineness in alloys covered by ISO 9202.

This document specifies a procedure for the determination of saturated and aromatic hydrocarbons (from C10 to C50) in vegetable fats and oils using the online-coupled high performance liquid chromatography-gas chromatography-flame ionization detection (HPLC-GC-FID). This document does not apply to other matrices.
The method is applicable for the analysis of mineral oil saturated hydrocarbons (MOSH) and/or mineral oil aromatic hydrocarbons (MOAH).
According to the results of the interlaboratory studies, the method has been proven suitable for MOSH mass concentrations above 3 mg/kg and MOAH mass concentrations above 2 mg/kg.
In case of suspected interferences, the fossil origin of the MOSH and MOAH fraction can be verified by examination by GC⨯GC-MS.
An alternative method for the epoxidation of the MOAH fraction (performic acid epoxidation) is proposed in Annex C. This alternative method provides comparable results to the ethanolic epoxidation of the MOAH fraction described in 8.6. This alternative method for epoxidation has proven to be efficient for samples with a high amount of interferences in the MOAH fraction (e.g. tropical oils).

ABSTRACT
This specification describes the required properties and test methods for high-solids content, cold liquid-applied elastomeric membrane with integral wearing surface for waterproofing building decks not subject to hydrostatic pressure. This specification does not include specific requirements for skid resistance or fire retardance, although both may be important in specific uses. The properties to which the materials will be tested upon for conformance are as follows: weight loss of base coat; low temperature crack bridging; adhesion-in-peel to cement mortar and plywood substrates after water immersion; chemical resistance after water, ethylene glycol, and mineral spirits exposure; weathering resistance, recovery from elongation, tensile retention, and elongation retention; abrasion resistance; and stability.
SCOPE
1.1 This specification describes the required properties and test methods for a cold liquid-applied elastomeric membrane for waterproofing building decks not subject to hydrostatic pressure. The specification applies only to a membrane system that has an integral wearing surface. This specification does not include specific requirements for skid resistance or fire retardance, although both may be important in specific uses.  
1.2 The type of membrane system described in this specification is used for pedestrian and vehicular traffic and in high-abrasion applications. The membrane may be single or multi-component, and may consist of one or more coats (for example base coat, top coat, etc.). The coat(s) may be built to the desired thickness in one or more applications. One coat (base coat) provides the primary waterproofing function and normally comprises the major amount of organic material in the membrane. The function of the top coat(s) is to resist wear and weather. Aggregate may be used as a component of the membrane system, as all or part of a course, to increase wear and skid resistance.  
1.3 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.  
1.4 Test methods in this specification require a minimum 0.5 mm [0.020 in.] base coat dry film thickness. Actual thickness required for a particular application and the use of aggregate in top coats shall be established by the membrane manufacturer.  
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.6 The following safety hazards caveat pertains only to the test method portion, Section 5, of this specification: This standard does not purport to address all of the safety problems, 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.

ABSTRACT
This specification covers permanent metal railing systems (such as guard, stair, and ramp-rail systems) and rails (such as hand, wall, grab, and transfer rails) for use in agricultural, assembly, commercial, educational, industrial, institutional, recreational, and residential buildings. Also covered in this specification are basic design requirements and considerations, and minimum criteria for load and deflections; however, it does not cover design criteria for specific field conditions. Railing systems and rails shall be manufactured with major structural components made of metal and secondary components made of metal, wood, plastics, or glass, and shall withstand forces that may potentially be exerted by building users. Tests for static loading and deflection shall be performed and shall conform to the requirements specified.
SIGNIFICANCE AND USE
5.1 Metal railing systems and rails for buildings usually are designed, manufactured, and installed to withstand forces potentially exerted by the building users.  
5.2 The metal railing systems and rails shall not be considered a part of the structural system of the building unless this is expressly provided for in the design.
SCOPE
1.1 This specification2 covers permanent metal railing systems (guard, stair, and ramp-rail systems) and rails (hand, wall, grab, and transfer rails) installed in and for agricultural, assembly, commercial, educational, industrial, institutional, recreational, and residential buildings. However, this standard does not cover metal railing systems installed in and for industrial, commercial, and other non-residential workplace occupancies where normally only adults will be present or have access, and for which guardrail or handrail requirements are specified by occupational safety and health safety regulations and standards. This standard does not cover ballasted railing systems.  
1.2 This specification is intended to be applied to permanent metal railing systems for buildings and to such railing systems and rails having major structural components made of metal, with their secondary components made of metal or other materials such as wood, plastics, and glass.  
1.3 This specification considers that today's and tomorrow's overall outlook is based on the health and safety of all potential users of buildings. The criteria incorporated in this specification provide for normal and anticipated building uses, but not for abuses for which the building and its components are not designed.  
1.4 This specification establishes basic minimum requirements and criteria that lead to satisfactory products under normal use conditions and does not give consideration to design criteria for specific field conditions, the establishment of which is the prerogative and responsibility of the designer, specification writer, and code agencies.  
1.5 Sources of supportive information are listed in the Reference section (1-28).3  
1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
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.

SIGNIFICANCE AND USE

Factors that influence the tensile response and should be reported include the following: material, methods of material preparation and lay-up, specimen stacking sequence, specimen preparation, specimen conditioning, environment of testing, specimen alignment and gripping, speed of testing, time at temperature, and volume percent reinforcement. Properties, in the test direction, which may be obtained from this test method include the following:  
5.1.1 Ultimate tensile strength,  
5.1.2 Ultimate tensile strain,  
5.1.3 Tensile modulus of elasticity, and  
5.1.4 Poissons ratio.
SCOPE
1.1 This test method covers the determination of the tensile properties of metal matrix composites reinforced by continuous and discontinuous high-modulus fibers. Nontraditional metal matrix composites as stated in 1.1.6 also are covered in this test method. This test method applies to specimens loaded in a uniaxial manner tested in laboratory air at either room temperature or elevated temperatures. The types of metal matrix composites covered are:  
1.1.1 Unidirectional laminates (all fibers aligned in a single direction) containing either continuous or discontinuous reinforcing fibers. Both longitudinal and transverse properties may be obtained.  
1.1.2 0°/90° balanced crossply laminates containing either continuous or discontinuous reinforcing fibers.  
1.1.3 Angleply laminates containing continuous reinforcing fibers, with layups that do not include 0° reinforcing fibers (that is, (±45)ns, (±30)ns, and so forth).  
1.1.4 Multidirectional laminates containing continuous reinforcing fibers, with layups including 0° reinforcing fibers (that is, (0/±45/90)ns quasi-isotropic laminates, (0/±30)ns laminates, and so forth).  
1.1.5 Laminates containing unoriented and random discontinuous fibers.  
1.1.6 Directionally solidified eutectic composites.  
1.2 The technical content of this standard has been stable since 1996 without significant objection from its stakeholders. As there is limited technical support for the maintenance of this standard, changes since that date have been limited to items required to retain consistency with other ASTM D30 Committee standards. The standard therefore should not be considered to include any significant changes in approach and practice since 1996. Future maintenance of the standard will only be in response to specific requests and performed only as technical support allows.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.  
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.

ABSTRACT
This specification covers poly(vinyl chloride) (PVC) pipe made in standard thermoplastic pipe dimension ratios and pressure rated for water. Poly(vinyl chloride) plastics used to make pipe meeting the requirements of this specification are categorized in two criteria: short-term strength tests, and long-term strength tests. The products covered by this specification are intended for use with the distribution of pressurized liquids only, which are chemically compatible with the piping materials. The material shall conform to the required wall thickness, sustained pressure, burst pressure, flattening, extrusion quality, and impact resistance. It shall be subject to an accelerated regression test.
SCOPE
1.1 This specification covers poly(vinyl chloride) (PVC) pipe made in standard thermoplastic pipe dimension ratios and pressure rated for water (see appendix). Included are criteria for classifying PVC plastic pipe materials and PVC plastic pipe, a system of nomenclature for PVC plastic pipe, and requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, flattening, and extrusion quality. Methods of marking are also given.  
1.2 The products covered by this specification are intended for use with the distribution of pressurized liquids only, which are chemically compatible with the piping materials. Due to inherent hazards associated with testing components and systems with compressed air or other compressed gases, some manufacturers do not allow pneumatic testing of their products. Consult with specific product/component manufacturers for their specific testing procedures prior to pneumatic testing.
Note 1: Pressurized (compressed) air or other compressed gases contain large amounts of stored energy which present serious safety hazards should a system fail for any reason.
Note 2: This standard specifies dimensional, performance and test requirements for plumbing and fluid handling applications, but does not address venting of combustion gases.  
1.3 The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.  
1.4 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.  
1.5 The following safety hazards caveat pertains only to the test methods portion, Section 8, 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. A specific precautionary statement is given in Note 9.
Note 3: CPVC plastic pipe (SDR-PR), which was formerly included in this specification, is now covered by Specification F442/F442M.  
Note 4: The sustained and burst pressure test requirements, and the pressure ratings in the appendix, are calculated from stress values obtained from tests made on pipe 4 in. (100 mm) and smaller. However, tests conducted on pipe as large as 24 in. (600 mm) in diameter have shown these stress values to be valid for larger diameter PVC pipe.  
Note 5: PVC pipe made to this specification is often belled for use as line pipe. For details of the solvent cement bell, see Specification D2672 and for details of belled elastomeric joints, see Specifications D3139 and D3212.

This test method is intended for use with other ASTM standards (see 2.1) that address the collection and preparation of samples (airborne particulate, dusts by wipe and micro-vacuuming, dried paint chips, and soils) that are obtained during the assessment or mitigation of lead hazards. This test method may be used to analyze samples collected from various environments, such as workplaces, buildings, indoor or outdoor settings, construction sites, housing, and so on.  
5.2 This test method may also be used to analyze similar samples from other environments such as toxic characteristic extracts of waste sampled using Guide E1908, and soil and sludge as prepared for analysis using U.S. EPA SW-846 Test Method 1311 (5).  
5.3 This test method can be relied upon by laboratories seeking accreditation for lead analysis by means of GFAAS.
SCOPE
1.1 This test method covers the determination of lead (Pb) in airborne particulate, dust by wipe and micro-vacuuming, paint, and soil collected in and around buildings and related structures using graphite furnace atomic absorption spectrometry (GFAAS).  
1.2 This test method contains directions for sample analysis, as well as quality assurance (QA) and quality control (QC), and may be used for purposes of laboratory accreditation and certification.  
1.3 No detailed operating instructions are provided because of differences among various makes and models of suitable GFAAS instruments. Instead, the analyst shall follow the instructions provided by the manufacturer of the particular instrument.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4.1 Exception—The SI and inch-pound units shown for wipe and micro-vacuuming sampling data are to be individually regarded as standard for wipe and micro-vacuuming sampling data.  
1.5 This test method contains notes which are explanatory and not part of the mandatory requirements of 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.

SCOPE
1.1 These test methods describe three bench top test methods for measuring the thermophysical responses of gypsum boards and panels when exposed to high temperatures. The test methods are:  
1.1.1 High-temperature Core Cohesion—This test method evaluates the ability of the test specimen to withstand a specified mechanical strain while exposed to elevated temperature.  
1.1.2 High-temperature Shrinkage—This test method evaluates dimensional changes in the test specimen when exposed to elevated temperatures.  
1.1.3 High-temperature Thermal Insulation—This test method evaluates the rate of heat transfer through the thickness of the test specimen by measuring the length of time required to heat the center of the test specimen over a specified temperature rise when exposed to prescribed furnace conditions.  
1.2 The test methods appear in the following order:    
Test Method  
Section  
High-temperature Core Cohesion  
4  
High-temperature Shrinkage  
5  
High-temperature Thermal Insulation  
6  
1.3 Units—The values stated in either inch-pound units or SI units (given in parenthesis) are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.4 While these tests are useful for evaluating fire properties of gypsum boards and panels, they are not suitable for predicting the Test Methods E119 fire resistance performance of a specific gypsum protected assembly that has not previously been tested in accordance with Test Methods E119 and correlated to these tests.2  
1.5 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.  
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.

SIGNIFICANCE AND USE
5.1 Some PFAS have been implicated in adverse human health impacts (4, 5, 6). Therefore, quantifying PFAS concentrations in indoor air is important for accurate and meaningful exposure analysis and risk assessments.  
5.2 PFAS found in air can have a wide range of chemical characteristics that will impact sampling practice selection. For example, estimated vapor pressure values can vary by ten orders of magnitude, while estimated Henry’s Law constants can vary by five orders of magnitude (Table 1). This means that sampling and analytical methods that are appropriate for one PFAS compound may not be appropriate for other PFAS compounds. Hence, prior to sampling and selecting analytic methods for PFAS measurement in indoor air, it is critical to establish that the chosen PFAS sampling method(s) is appropriate for the target compound(s), the sampling location, and the environmental conditions.  
5.3 The measurement of PFAS in indoor air is an active and growing research topic. Understanding of PFAS properties, sampling and analytic approaches and techniques is constantly evolving. This includes the determination of physical-chemical properties of many PFAS, which may not even have been measured experimentally or which have a wide range of experimentally determined properties (that is, 8:2 FTOH in Table 1). This guide describes methods that are in use at the time of publication.  
5.4 PFAS in indoor air may come from a wide range of sources, including consumer products, building materials, food packaging, outdoor air, and other miscellaneous sources. PFAS is also commonly quantified in indoor dust. There are several methods that quantify these chemicals in solid and liquid media including, but not limited to Guide E3302, Test Method D7968, Test Method D7979, Test Method D8421, Test Method D8535, US EPA 533, and US EPA 537.1. US EPA OTM-45 quantifies some PFAS in the combined gas and particle phases of stationary sources, such as incinerator stack sampling.
