ASTM D3311-94

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

SCOPE
1.1 This specification provides standard fitting geometries and laying lengths for plastic fittings intended for use in drain, waste, and vent applications.
1.2 Fittings meeting the requirements of this standard specification are designed for use with outside diameter controlled pipe. The 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 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.
