Copper Fitting Standards

Copper copper alloy tube and pipe.

Copper fitting standards.

Cleanliness for copper tube and fittings that are used for specific applications like medical gas astm b819 and hvacr systems astm b280 additional cleanliness requirements are included in the standards to ensure that the interior tube surface does not introduce any contaminants that might interfere with the safety or operation of the system. The standard establishes specifications for wrought copper and wrought copper alloy solder joint seamless fittings designed for use with seamless copper tube conforming to astm b 88 water and general plumbing systems b 280 air conditioning and refrigeration service and b 819 medical gas systems as well as fittings intended to be assembled with soldering materials conforming to astm b 32 brazing materials conforming to aws a5 8 or with tapered pipe thread conforming to asme b1 20 1. Astm s copper standards are instrumental in classifying evaluating and specifying the material chemical mechanical and metallurgical properties of copper materials including bronze and their alloys with other metals. Astm b 251 standard specification for general requirements for wrought seamless copper and copper alloy tube covers a number of general requirements common to many wrought copper products.

In medical gas systems this prevents contamination of the gases used in healing and maintaining life. Fittings manufactured to this standard are to have a copper cu content of not less than 84. A few of these specifications are b 68 b75 b135 b466 and b743. Copper copper alloy tube pipe fittings standards this is a white paper developed by the cda to provide a comprehensive listing of various standards that are applicable to copper copper alloy tube pipe and fittings.
