2、vision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification provides standard fitting geometriesand laying lengths for plastic fittings in
3、tended for use in drain,waste, and vent applications. (See Specifications D2661 andD2665.)1.2 Fittings meeting the requirements of this standard speci-fication are designed for use with outside diameter controlledpipe. The inside diameter can vary significantly as the wallthickness and outside diame
