1.1 This specification establishes the requirements for welded copper tube for air conditioning and refrigeration service for use in connections, repairs, and alterations. The tube shall be made from one of the following coppers:
|Copper UNS No.||Previously Used Designation||Type of Copper|
|C10200||OF||Oxygen-free without-residual oxidants|
|C12000||DLP||Phosphorus-deoxidized, low-residual phosphorus|
|C12200||DHP||Phosphorus-deoxidized, high-residual phosphorus|
Note 1—Fittings used for soldered or brazed connections in air conditioning and refrigeration systems are described in ASME Standard B 16.22.
Note 2—The assembly of copper tubular systems by soldering is described in Practice B828.
1.2 Copper UNS No. C12200 shall be furnished, unless otherwise specified. The copper tube shall be supplied in annealed coils or drawn temper straight lengths.
1.3 Units—Values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units which are provided for information only and are not considered standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
