ASTM F913-95

Standard Specification for Thermoplastic Elastomeric Seals (Gaskets) for Joining Plastic Pipe

SCOPE
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 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.
