ASTM B483/B483M-20

1.1This specification covers aluminum and aluminum-alloy drawn tube and drawnpipe in straight lengths and tube in coils for general purpose applications and climate control (HVAC) in the alloys (Note 2) and tempers shown in Tables 1-3. Coiled tubes are generally available only as round tubes with a wall thickness not exceeding 0.083 in. [2.00 mm] and only in non-heat-treatable alloys.

1.2Alloy and temper designations are in accordance with ANSI H35.1/H35.1M. The equivalent Unified Number System alloy designations are those of Table 4 preceded by A9, for example A91060 for aluminum 1060 in accordance with Practice E527.

1.3For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.

1.4The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.

1.5This 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.

1.6This 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.
