本标准规定了用于排水、废水和通风（DWV）系统的铸造铜合金焊接接头排水配件的规范。这些配件设计用于符合ASTM B306的无缝铜管、铜排水管（DWV）以及拟用符合ASTM B32的焊接材料或符合ASME B1.20.1的锥形管螺纹组装的配件。 本标准与ASME B16.29《锻铜和锻铜合金钎焊排水管件》相结合- DWV。它提供了适合焊接的装配端的要求。本标准包括:（a）说明（b）节距（斜率）（c）端部连接的缩写（d）缩径管件开口设计的尺寸和方法（e）标记（f）材料（g）尺寸和公差

This Standard establishes specifications for cast copper alloy solder joint drainage fittings, designed for use in drain, waste, and vent (DWV) systems. These fittings are designed for use with seamless copper tube conforming to ASTM B306, Copper Drainage Tube (DWV), as well as fittings intended to be assembled with soldering materials conforming to ASTM B32, or tapered pipe thread conforming to ASME B1.20.1. This Standard is allied with ASME B16.29, Wrought Copper and Wrought Copper Alloy Solder Joint Drainage Fittings - DWV. It provides requirements for fitting ends suitable for soldering. This Standard covers:(a) description(b) pitch (slope)(c) abbreviations for end connections(d) sizes and methods for designing openings for reducing fittings(e) marking(f) material(g) dimensions and tolerances
