Standard Specification for Compression Joints for Vitrified Clay Pipe and Fittings
|Publication Date:||1 April 2004|
|ICS Code (Flanges, couplings and joints):||23.040.60|
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 1Install pipe in accordance with Practice C 12.
The following precautionary caveat pertains only to the Test Requirements portion, Section , 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.

This specification covers vitrified clay pipe and fitting materials and pipe joint assemblies test requirements for compression joints. Sealing elements shall be compressed and bounded between bearing surfaces to assure watertight integrity. Materials and manufacture, such as rubber ring-sealing elements, plastic components, and metallic components, shall conform to the chemical resistance, tensile strength, hardness, compression set, water absorption, ozone resistance, and accelerated oven aging requirements of the specification. Minimum of two assembled joints shall be tested for each diameter of pipe furnished. Joints shall be subjected to water pressure testing and shall not leak even when deflected, displaced or subjected to shear under the limits indicated in the specification.View Less
