This specification covers the requirements for seamless UNS C10200, C12000, or C12200 copper alloy tubes used for connection, repairs, or alternations of field air conditioning or refrigeration units. Materials in the form of billets, bars, or tubes should be used to produce a homogeneous uniform wrought structure by either hot or cold working. Each tube should be cold drawn to the finished size and wall thickness. Coiled lengths with soft annealed tempers should be bright annealed after coiling then dehydrated and either capped, plugged, crimped, or otherwise closed at both ends. Straight lengths with hard drawn tempers should be cleaned and either capped, plugged, or otherwise closed at both ends. The grain sizes, tensile properties, and eddy-current and cleanness test results should conform to the values listed herein.
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 .
Note 3: Solders for joining copper tubular systems are described in Specification . The requirements for acceptable fluxes for these systems are described in Specification .
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:
Oxygen free without
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 of this specification: 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
