ASTM C425-01

Standard Specification for Compression Joints for Vitrified Clay Pipe and Fittings

SCOPE
1.1 This specification covers materials and test requirements for compression joints for vitrified clay pipe and fittings. See Specification C 700 for pipe specifications. The test requirements are applicable to pipe joint assemblies prior to field installation of pipe.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
Note 1—Install pipe in accordance with Practice C 12.
1.3 The following precautionary caveat pertains only to the Test Requirements portion, Section 7, of this standard. 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.
