ASME B16.51-2013

This Standard establishes requirements for cast copper alloy, wrought copper, and wrought copper alloy, press-connect 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 are for use at a maximum pressure of 1380 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 size designations, pressure-temperature ratings, terminology, dimensions and tolerances, materials, design qualification, required installation instructions, and markings.
