1.1 This specification covers externally helical, integrally finned aluminum and aluminum-alloy seamless tubes with finned or unfinned ends, with continuous fins, or with unfinned sections, in outside diameters (diameter over fins) up to 2 in. [50 mm] inclusive. See Table 1 and Table 2.
1.2 Alloy and temper designations are in accordance with ANSI H35.1 and H35.1M. The equivalent Unified Numbering System alloy designations are those of Table 1 preceded by A9, for example, A91060 for aluminum 1060 in accordance with Practice E 527. NOTE 1—Throughout this specification the term alloy in the general sense includes aluminum as well as aluminum alloy.
1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
1.4 The 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 are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
