1.1 This specification describes seamless copper and copper alloy tubing on which the external or internal surface, or both, has been modified by a cold-forming process to produce an integral enhanced surface for improved heat transfer. The tubes are used in surface condensers, evaporators, and heat exchangers and are normally made from the following copper or copper alloys:
Copper or Copper Alloy UNS No. Type of Metal C10100 Oxygen-free electronic C10200 Oxygen-free without residual deoxidants C10300 Oxygen-free, extra low phosphorus C10800 Oxygen-free, low phosphorus C12000 DLP Phosphorized, low residual phosphorus C12200 DHP, Phosphorized, high residual phosphorus C14200 DPA Phosphorized arsenical C19200 Phosphorized, 1 % iron C23000 Red Brass C44300 Admiralty Metal Types B, C44400 C, and C44550 D C60800 Aluminum Bronze C68700 Aluminum Brass Type B C70400 95-5 Copper-Nickel C70600 90-10 Copper-Nickel C71000 80-20 Copper-Nickel Type A C71500 70-30 Copper-Nickel C72200 Copper-Nickel1.2 The following safety hazard caveat pertains only to the test methods described in this specification.
1.2.1 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.
Note 2-A complete metric companion, B359M, has been developed; therefore, no metric equivalents are presented.
