This specification covers requirements and test methods for materials, dimensions, workmanship, flattening resistance, impact resistance, pipe stiffness, extrusion quality, joining systems and a form of marking for type PSM poly(vinyl chloride) (PVC) SDR 51 and SDR 64 sewer pipe and fittings. In the solvent cement joint, the pipe spigot wedges into the tapered socket and the surfaces fuse together. Joints made with pipe and fittings shall show no signs of leakage when tested. The pipe dimensions, fitting dimensions, pipe flattening, impact resistance, pipe stiffness, joint tightness, and extrusion quality shall be tested to meet the requirements prescribed.1.1 This specification covers requirements and test methods for materials, dimensions, workmanship, flattening resistance, impact resistance, pipe stiffness, extrusion quality, joining systems and a form of marking for type PSM poly(vinyl chloride) (PVC) SDR 51 and SDR 64 sewer pipe and fittings.1.2 Pipe and fittings produced to this specification should be installed in accordance with Practice D2321.1.3 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 precautionary 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.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.

4.1 These procedures can be used to evaluate chemicals or materials expected to come in contact with plastic piping relative to causing environmental stress-cracking in thermoplastic materials. This testing results in determining time-to-failure versus engineering stress. This procedure can also be used in stress-rupture regression analysis, where a variety of stress levels are needed. The methodology can be readily adapted to conducting immersion tests in liquids or testing temperatures other than 73 °F (23 °C).1.1 This test method is used for determining chemical compatibility of substances in contact with thermoplastic pipe and fittings materials.1.2 This test method is not intended to evaluate the suitability of solvent cements or adhesives used to join plastic piping.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers plastic insert fittings for polyethylene (PE) plastic pipe. The fittings shall be made from one of the following plastics: nylon plastics, propylene plastics, and poly(vinyl chloride) plastics. Dimensions and burst pressure for the fittings should meet the requirements specified. The fittings shall be homogeneous throughout and free of cracks, holes, foreign inclusions, or other defects. The fittings shall be as uniform as commercially practicable in color, opacity, density, and other physical properties.1.1 This specification covers plastic insert fittings for polyethylene (PE) plastic pipe, and also PVC insert fittings for PE to PVC pipe transitions. Included are requirements for materials, workmanship, dimensions, and burst pressure.1.2 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.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4  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.
