ASTM D3311-22

Standard Specification for Drain, Waste, and Vent (DWV) Plastic Fittings Patterns

ABSTRACT
This specification illustrates the standard fitting geometries and laying lengths of plastic fittings intended for use with outside diameter controlled pipes in drain, waste, and vent (DWV) applications.
SCOPE
1.1 This specification provides standard fitting geometries and laying lengths for plastic fittings intended for use in drain, waste, and vent applications. (See Specifications D2661 and D2665.)  
1.2 Fittings meeting the requirements of this standard specification are designed for use with outside diameter controlled pipe. The inside diameter of pipe can vary significantly as the wall thickness and outside diameter varies and therefore is not suitable for use as a fitting socket.  
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 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
