| 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 B 828.
Note 3—Solders for joining copper tubular systems by described in Specification B 32. The requirements for acceptable fluxes for these systems are described in Specification B 813.
