This Standard establishes requirements for cast copper alloy, wrought copper, and wrought copper alloy pressconnect pressure fittings for use with hard-drawn seamless copper water tube conforming to ASTM B88 for piping systems conveying water. The press-connect system (tube, fitting, and joint) conforming to this Standard is for use at a maximum pressure of 1 380 kPa (200 psi) over the temperature range from 0°C to 93°C (32°F to 200°F).
This Standard provides requirements for fittings suitable for press-connect joining and covers the following:
(a) terminology
(b) size designations
(c) marking
(d) material
(e) dimensions and tolerances
(f) required installation instructions
(g) pressure–temperature ratings
(h) design qualification
