CONTAINED IN VOL. 02.01, 2017 Specifies the requirements for welded copper tube for air conditioning and refrigeration service for use in connections, repairs, and alterations.

1.1This 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

C10100

OFE

Oxygen-free electronic

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.
Note 3—Solders for joining copper tubular systems by descirbed in Specification B32. The requirements for acceptable fluxes for these systems are described in Specification B813.

1.2Copper UNS No. C12200 shall be furnished, unless otherwise specified. The copper tube shall be supplied in annealed coils or drawn temper straight lengths.

1.3Units—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.

1.4This 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.
