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 Designation: D3311 − 17 An American National Standard Standard Specification for Drain, Waste, and Vent (DWV) Plastic Fittings Patterns1 This standard is issued under the fixed designation D3311; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision A number in parentheses indicates the year of last reapproval A superscript epsilon (´) indicates an editorial change since the last revision or reapproval Scope* D2661 Specification for Acrylonitrile-Butadiene-Styrene (ABS) Schedule 40 Plastic Drain, Waste, and Vent Pipe and Fittings D2665 Specification for Poly(Vinyl Chloride) (PVC) Plastic Drain, Waste, and Vent Pipe and Fittings F1498 Specification for Taper Pipe Threads 60° for Thermoplastic Pipe and Fittings 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 can vary significantly as the wall thickness and outside diameter varies and therefore is not suitable for use as a fitting socket Requirements 3.1 Fittings shall conform to the geometries and laying lengths as shown in Tables 1-45 and Figs 1-5 Tolerances shall be 61⁄16 in unless otherwise specified 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 3.2 Spigot and hub dimensions shall conform to the requirements of the referencing standard 3.3 The exact outside shape of a fitting is not determined by the outline drawings shown in this specification but rather by the socket dimensions, wall thickness requirements, waterway, laying lengths, and any other critical dimensions that may be specified 3.4 The pitch of sockets for patterns with 90° angles (except vent fittings) shall be 1⁄4 in./ft or 1° 12 Referenced Documents 3.5 On double reducing sanitary tees, the G2 dimension on branches will be calculated on the larger size and centerlines shall remain the same for both branches
