ASTM B280-20

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: B280 − 19 B280 − 20
Standard Specification for
Seamless Copper Tube for Air Conditioning and

Refrigeration Field Service
This standard is issued under the fixed designation B280; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope*
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 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 The tube shall be produced from the following coppers, and the manufacturer has the option to supply any one of them,
unless otherwise specified:
Copper Previously Used
Description
UNS No. Designation
C10200 OF Oxygen free without
residual deoxidants
C12000 DLP Phosphorus deoxidized,
low residual phosphorus
C12200 DHP Phosphorus deoxidized,
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 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, 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.
