1、Designation: D 3311 09aAn American National StandardStandard Specification forDrain, Waste, and Vent (DWV) Plastic Fittings Patterns1This standard is issued under the fixed designation D 3311; the number immediately following the designation indicates the year oforiginal adoption or, in the case of
2、revision, 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
3、intended for use in drain,waste, and vent applications. (See Specifications D 2661 andD 2665.)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 d
4、iameter 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
