2、 year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers a
3、luminum and aluminum-alloy(Note 1) formed and arc-welded round tube in diameters 9 to60 in. 230 to 1520 mm, made from formed sheet or plate, buttwelded by gas-tungsten or gas-metal arc-welding methods withor without the use of filler metal.NOTE 1Throughout this specification use of the term alloy in
4、 thegeneral sense includes aluminum as well as aluminum alloy.NOTE 2The requirements for the sheet and plate used are the same asin Specifications B 209 or B 209M.1.2 Alloy and temper designations are in accordance withANSI H35.1 H35.1M. The equivalent Unified NumberingSystem alloy designations are
5、those of Table 1 preceded by A9,for example, A91100 for aluminum 1100 in accordance withPractice E 527.1.3 For acceptance criteria for inclusion of new aluminumand aluminum alloys in this specification, see Annex A2.1.4 The values stated in either inch-pound or SI units are tobe regarded separately
6、as standards. The SI units are showneither in brackets or in separate tables. The values stated ineach system are not exact equivalents; therefore, each systemmust be used independently of the other. Combining valuesfrom the two systems will result in nonconformance with thespecification.2. Referenc

If tubing is produced by welding individuallyfabricated sections together, longitudinal butt welds shall bepositioned so as to be at least 45 apart.6. Quality Assurance6.1 Responsibility for InspectionUnless otherwise speci-
42、fied in the contract or purchase order, the producer or supplieris responsible for the performance of all inspection and testrequirements specified herein. Except as otherwise specified inthe contract or order, the producer or supplier may use his ownor any other suitable facilities for the performa
43、nce of theinspection and test requirements specified herein, unless dis-approved by the purchaser. The purchaser shall have the rightto perform any of the inspections and tests set forth in thisspecification where such inspections are deemed necessary toassure that the material conforms to prescribe
44、d requirements.6.2 Lot DefinitionAn inspection lot shall be defined asfollows:6.2.1 For heat-treated tempers, an inspection lot shall con-sist of all material of the same mill form, alloy, temper, andnominal dimensions traceable to a heat-treat lot or lots, andsubjected to inspection at one time.6.2
45、.2 For nonheat-treated tempers, an inspection lot shallconsist of all material of the same mill form, alloy, temper, andnominal dimensions subjected to inspection at one time.TABLE 2 Mechanical Property Limits (Inch-Pound Units)A,B,CTemperSpecified Thick-ness, in.Tensile Strength, ksi Yield Strength
