Copper Fitting Standards
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.
Copper fitting standards. These materials when in the raw form are fabricated into basic shapes like sheets strips plates bars beams disks rods wires and ingots. The listing of standards is grouped under two sections. 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. Copper copper alloy tube and pipe.
A few of these specifications are b 68 b75 b135 b466 and b743. 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. Fittings manufactured to this standard are to have a copper cu content of not less than 84. 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.
