Historical (view previous versions of standard)
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.
