1.1 This specification establishes the requirements for seamless copper tube intended for use in the connection, repairs, or alternations of air conditioning or refrigeration units in the field.
Note 1—Fittings used for soldered or brazed connections in air conditioning and refrigeration systems are described in ASME Standard B16.22.
Note 2—The assembly of copper tubular systems by soldering is described in Practice B 828
Note 3—Solders for joining copper tubular systems are described in Specification B 32
1.2 The tube shall be produced from the following coppers, and the manufacturer has the option to supply any one of them, unless otherwise specified:
|C10200||OF||Oxygen free without|
low residual phosphorus
high residual phosphorus
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 The following hazard statement pertains only to the test method described in Section 18.2.4 of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use.
