(Specification)Standard Specification for Molded Drain, Waste, and Vent (DWV) Short-Pattern Plastic Fittings
Standard Specification for Molded Drain, Waste, and Vent (DWV) Short-Pattern Plastic Fittings
ABSTRACT
This specification covers standard fitting geometries for molded short-pattern plastic fittings intended for use in drain, waste, and vent applications. Fittings meeting the requirements of this specification are designed for use with outside-diameter controlled pipe. The body inside diameter can vary significantly as the wall thickness and outside diameter varies, and therefore, is not suitable for use as a fitting socket. Compliance to the specified centerline radius of curvature of short-pattern ¼ bends and the side branch of short-pattern sanitary tees shall be tested.
SCOPE
1.1 This specification covers standard fitting geometries for molded short-pattern plastic fittings intended for use in drain, waste, and vent applications.
1.2 Fittings meeting the requirements of this specification are designed for use with outside-diameter controlled pipe. The body inside diameter can vary significantly as the wall thickness and outside diameter varies, and therefore, is not suitable for use as a fitting socket.
1.3 Fittings meeting the requirements of this specification shall be tested in accordance with the applicable requirements of Specifications D2661 or D2665.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units which are provided for information only and are not considered standard.
1.5 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.
1.6 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.
