1.1 This specification covers aluminum-alloy (Note 1) drawn seamless round tube in straight lengths designated as shown in Table 2, for use in surface condensers, evaporators, and heat exchangers.
Note 1-Throughout this specification use of the term alloy in the general sense includes aluminum as well as aluminum alloy. Note 2-For drawn seamless tubes used in general applications, see Specification B210; for extruded tubes see Specification B221; for seamless pipe see Specification B241/B241M; and for structural pipe and tube see Specification B429.1.2 Alloy and temper designations are in accordance with ANSI H35.1. 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 E527.
1.3 A complete metric companion to Specification B234 has been developed-B234M; therefore, no metric equivalents are presented in this specification.
1.4 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
