(Specification)Standard Specification for Shielded Transition Couplings Using Flexible Poly Vinyl Chloride (PVC) Gaskets to Connect Dissimilar DWV Pipe and Fittings
Standard Specification for Shielded Transition Couplings Using Flexible Poly Vinyl Chloride (PVC) Gaskets to Connect Dissimilar DWV Pipe and Fittings
ABSTRACT
This specification covers the performance of shielded transition couplings using flexible PVC gaskets to join dissimilar DWV pipe and fittings above and below ground. The gaskets shall be permitted to be spliced or molded and all the steel parts shall be 300 series stainless steel excluding copper bearing alloys. Requirements for the coupling support and installation, elastomeric gasket, and clamp assembly are given. The testing apparatus and requirements for deflection test, shear test, and unrestrained hydrostatic joint test are detailed.
SCOPE
1.1 This specification covers the performance of shielded transition couplings using flexible PVC gaskets to join dissimilar DWV pipe and fittings above and below 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 committee with jurisdiction over this standard is not aware of any comparable standards of any other organization.
1.4 The following precaution pertains only to the test method portion, Sections 7 and 8 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 requirements prior to use.
