In medical gas systems this prevents contamination of the gases used in healing and maintaining life.
Copper fitting standards.
Copper copper alloy tube and pipe.
A few of these specifications are b 68 b75 b135 b466 and b743.
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 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.
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.
Wrought wrot copper alloy fittings used for drainage waste and vent applications with solder joints are manufactured to the requirements of ansi asme b16 29 wrought copper and wrought copper alloy solder joint drainage fittings dwv.
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.
