1. 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 15-in. pipe and fittings. This standard is intended to cover reducing couplings used to join pipes and fittings of different sizes, materials, and different outside diameters. 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 published by other organizations. 1.4?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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5?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. |
