Scope

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
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 B8201;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.

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