ASTM B280-99e1

Standard Specification for Seamless Copper Tube for Air Conditioning and Refrigeration Field Service

SCOPE
1.1 This specification establishes the requirements for seamless copper tube produced from Copper UNS No. C12200, and intended for use in the connection, repairs, or alterations 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 B828.
Note 3--Solders for joining copper tubular systems are described in Specification B32. The requirements for acceptable fluxes for these systems are described in Specification B813.
1.2 Values stated in inch-pound units are the standard except for grain size which is stated in SI units. SI values given in parentheses are for information only.  
1.3 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. 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.
