Anotace textu normy ASTM C425-22 :
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.
Keywords:
angular joint, bell, chemical resistance, clay pipe, compression joints, corrosion resistance, couplings, deflection, joints, sealing elements, shear, testing,, ICS Number Code 23.040.60 (Flanges, couplings and joints)

1.1?This specification covers materials and test requirements for compression joints for vitrified clay pipe and fittings. See Specification C700 for pipe specifications. The test requirements are applicable to pipe joint assemblies prior to field installation of pipe. Note 1:?Install pipe in accordance with Practice C12.
1.2?The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
