Standard Specification for Compression Joints for Vitrified Clay Pipe and Fittings
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
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.
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 1Install pipe in accordance with Practice C 12.
