1.1 This specification 2 covers aluminum and aluminum-alloy drawn seamless tubes in straight lengths and coils for general purpose and pressure applications in alloys ( Note 2 ), tempers, and thicknesses shown in Table 2 [ Table 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. Wall Thickness, in. [Wall Thickness, mm] Location up through 0.100 surface of tensile sample [up through 2.50] 0.101 and over sub-surface after removal of approximately 10 % of thickness [over 2.50] 1.2 Alloy and temper designations are in accordance with ANSI H35.1/H35.1M. The equivalent Unified Numbering System alloy designations are those of Table 1 preceded by A9, for example, A91100 for aluminum designation 1100 in accordance with Practice E527 . Note 1: See Specification B483/B483M for aluminum-alloy drawn tubes for general purpose applications; Specification B234 for aluminum-alloy drawn seamless tubes for condensers and heat exchangers; and Specification B241/B241M for aluminum-alloy seamless pipe and seamless extruded tube. Note 2: Throughout this specification, use of 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 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.
