Standard Test Method for Assessment of Intra-operative Durability of Intervertebral Body Fusion Devices

Standard Test Method for Assessment of Intra-operative Durability of Intervertebral Body Fusion Devices

SIGNIFICANCE AND USE
5.1 IBFDs can be single-piece or multicomponent designs and can be porous or hollow in nature. Their function is to support the anterior column of the spine to facilitate arthrodesis of the motion segment.  
5.2 Intra-operative IBFD assembly failures can result in significant clinical consequences.4 This test method outlines materials and methods for the comparative characterization and evaluation of the intra-operative impact performance of IBFD assemblies.  
5.3 The impact forces applied during a surgical procedure may be highly variable and, therefore, the results from these tests may not directly predict in vivo performance. The results, however, can be used to compare mechanical performance of different IBFD assemblies. The tests may also identify the weakest, most likely to fail points in particular IBFD-inserter combinations, thus enabling design improvements.  
5.4 Intra-operative clinical failures may be due to several factors, some of which may not be simulated in the current method. For example, off-axis impact loads applied to the IBFD assembly are not simulated in the current method yet may contribute to intra-operative clinical failures in some designs. The user of this standard should consider incorporating such factors into their evaluations.
SCOPE
1.1 This test method covers the materials and methods for impact testing of lumbar intervertebral body fusion devices (IBFD).  
1.2 This test method is intended to provide a basis for the mechanical comparison among nonbiologic IBFD assemblies (the IBFD and associated inserter tool). This test method is intended to enable the user to compare these IBFD assemblies under impact loads to simulate the intra-operative surgical technique used to insert the IBFD.  
1.3 The test method describes the impact test by specifying impact energies and specific methods for applying these energies. The tests are designed to allow for the comparative evaluation of IBFD assemblies.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard, with the exception of angular measurements, which may be reported in terms of either degrees or radians.  
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.

Standard Specification for Permanent Metal Railing Systems and Rails for Buildings

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.

ASTM C957/C957M-17(2024)(Specification)
Standard Specification for High-Solids Content, Cold Liquid-Applied Elastomeric Waterproofing Membrane with Integral Wearing Surface

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.

ASTM D3552-24(Test Method)
Standard Test Method for Tensile Properties of Fiber Reinforced Metal Matrix Composites

SIGNIFICANCE AND USE
5.1 This test method is designed to produce tensile property data for material specifications, research and development, quality assurance, and structural design and analysis. 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.

Standard Guide for Determination of Airborne PFAS in the Indoor Air Environment

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.  
5.5 Thi...
SCOPE
1.1 This guide describes methods for determining Per- and Polyfluoroalkyl Substances (PFAS) concentrations in indoor air.  
1.2 This guide is focused on PFAS measurement technologies applicable to indoor air (including in vehicles and indoor workplaces) and other relevant air volumes such as, air in chambers, bags, or both. The described technologies were developed for indoor air; they may or may not be applicable to other types of air samples.  
1.3 This guide describes available technologies and methods that can be used to measure indoor air PFAS concentrations in the gaseous or particulate phases, or both, in indoor air.  
1.4 This guide describes each method and its advantages and limitations.  
1.5 This guide does not attempt to differentiate between the effectiveness of the methods nor determine equivalence of the methods.  
1.6 The sorbent-based sampling strategies addressed in this guide are for PFAS compounds with a molecular mass greater than 200 g mol-1 (1, 2, 3).2 Compounds less than 200 g mol-1, such as CF4, C2F6, or PFAS degradation products may require real-time analytical methods described in this guide or other methods that are not presented here.  
1.7 Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.  
1.8 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.

Standard Specification for Poly(Vinyl Chloride) (PVC) Pressure-Rated Pipe (SDR Series)

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.

Standard Test Methods for High-Temperature Characterization of Gypsum Boards and Panels

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:

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.

Standard Specification for Poly(Vinyl Chloride) (PVC) Profile Strip for Machine Spiral-Wound Liner Pipe Rehabilitation of Existing Sewers and Conduit

ABSTRACT
This specification covers the requirements and test methods for materials, dimensions, workmanship, stiffness factor, extrusion quality, and test procedures for extruded poly(vinyl chloride) (PVC) profile strips used for machine-made field fabrication of spirally wound pipe liners in the rehabilitation of a variety of existing pipelines and conduits including sanitary sewers, storm water sewers, process flow piping, and non-circular pipelines (such as arched or oval shapes and rectangular shapes) under gravity flow conditions. Certification, packaging, and product marking for quality assurance are also considered.
SIGNIFICANCE AND USE
9.1 The requirements of this specification are intended to provide extruded PVC profile strip suitable for the field fabrication of spirally wound liner pipe for the rehabilitation of existing pipelines and conduits conveying sewage, process flow, and storm water under gravity flowconditions.
Note 3: Industrial waste disposal lines should be installed only with the specific approval of the cognizant code authority since chemicals not commonly found in drains and sewers and temperatures in excess of 140 °F (60 °C) may be encountered.
SCOPE
1.1 This specification covers requirements and test methods for materials, dimensions, workmanship, stiffness factor, extrusion quality, and a form of marking for extruded poly(vinyl chloride) (PVC) profile strips used for machine made field fabrication of spirally wound pipe liners in the rehabilitation of a variety of gravity applications such as sanitary sewers, storm sewers, and process piping in diameters of 6 to 180 in. and for similar sizes of non-circular pipelines such as arched or oval shapes and rectangular shapes.  
1.2 Profile strip produced to this specification is for use in field fabrication of spirally wound liner pipes in nonpressure sewer and conduit rehabilitation, where the spirally wound liner pipe is expanded until it presses against the interior surface of the existing sewer or conduit, or, alternatively, where the spirally wound liner pipe is inserted as a fixed diameter into the existing sewer or conduit and the annular space between the liner pipe and the existing sewer or conduit is grouted.  
1.3 This specification includes extruded profile strips made only from materials specified in 5.1.  
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 precautionary caveat pertains only to the test method portion, Section 11, 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.  
1.6 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.
