This specification covers thermoplastic elastomeric seals (gaskets) used to seal the push-on joints of plastic pipe and fittings used for gravity and low-pressure applications. The gasket shall be fabricated from a high-grade thermoplastic elastomer meeting the following physical property requirements: tensile strength, elongation, hardness, low-temperature hardness, ozone resistance, accelerated aging, water immersion, and force decay or stress relaxation. All gaskets shall be extruded or molded in such a manner that any cross section will be dense, homogeneous, and free of porosity, blisters, pitting, or other imperfections.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers thermoplastic elastomeric seals (gaskets) used to seal the joints of plastic pipe and fittings used for gravity and low-pressure applications. This specification refers to push-on joints that require no internal or external pressure to effect the initial seal.
1.2 Requirements are given for thermoplastic elastomers.
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 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 and health practices and determine the applicability of regulatory limitations prior to use.
