(Specification)Standard Specification for Shielded Transition Couplings for Use With Dissimilar DWV Pipe and Fittings Above Ground
Standard Specification for Shielded Transition Couplings for Use With Dissimilar DWV Pipe and Fittings Above Ground
ABSTRACT
This specification deals with the performance of shielded transition couplings to join dissimilar DWV pipe and fittings above ground. All steel parts made from round stock shall be 300 series stainless steel. The elastomeric gasket shall consist of one piece and shall have an inside center stop-ring spaced equal distance from the ends. The clamp assembly shall be tested to withstand the stated installation torque. The following shall also be done: deflection test, shear test, and unrestrained hydrostatic joint test.
SCOPE
1.1 This specification covers the performance of shielded transition couplings to join dissimilar DWV pipe and fittings above ground up to and including 10 in. pipe and fittings.
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 precaution comment 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.
1.4 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.
