(Specification)Standard Specification for Heavy Duty Shielded Couplings Joining Hubless Cast Iron Soil Pipe and Fittings
Standard Specification for Heavy Duty Shielded Couplings Joining Hubless Cast Iron Soil Pipe and Fittings
ABSTRACT
This specification covers the performance evaluation of heavy duty shielded couplings to join hubless cast iron soil pipe and fittings. Physical properties of all stainless steel and gaskets shall comply with the specified values. Requirements for the elastomeric gasket, clamp assembly, and couplings such as coupling width are detailed. The test apparatus for deflection test, shear test, and unrestrained hydrostatic joint test are illustrated.
SCOPE
1.1 This specification covers the evaluating of the performance of heavy duty shielded couplings to join hubless cast iron soil pipe and fittings.
1.2 Couplings covered by this standard shall have nominal dimensions as found in Table 1 and Fig. 1 of this standard.
1.3 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.
1.4 The following precautionary caveat pertains only to the test method portion, Section 7, of this specification. 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.
