1、Designation: D3311 11An American National StandardStandard Specification forDrain, Waste, and Vent (DWV) Plastic Fittings Patterns1This standard is issued under the fixed designation D3311; the number immediately following the designation indicates the year oforiginal adoption or, in the case of rev
2、ision, 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. Scope1.1 This specification provides standard fitting geometriesand laying lengths for plastic fittings inte
3、nded 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 diamete
4、r varies and therefore is notsuitable for use as a fitting socket.1.3 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.2. Referenced Docum
