scope:

This Standard establishes requirements for cast copper alloy solder joint pressure fittings designed for use by soldering or brazing with seamless copper water tube conforming to ASTM B88. Fittings made in accordance with this Standard are intended to be assembled with soldering materials conforming to ASTM B32, brazing materials conforming to AWS A5.8, or tapered pipe thread conforming to ASME B1.20.1.

This Standard is allied to ASME B16.22 for wrought copper alloy pressure fittings and ASME B16.50, which covers wrought pressure fittings for brazing only.

This Standard provides requirements for fitting ends of suitable depth to achieve required pressure ratings when joined by either soldering or brazing. It establishes requirements for the following:

(a) pressure-temperature ratings

(b) abbreviations for end connections

(c) sizes and method of designating openings of fittings

(d) marking

(e) material

(f) dimensions and tolerances

(g) tests
