2、st 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. Scope*1.1 This specification covers aluminum-al
3、loy pipe and ex-truded tube in those selected alloys shown in Table 1 andtempers shown in Table 2, and in those standard sizes shown inTables 3 and 4, as well as in other nonstandard sizes as agreedupon between the purchaser and supplier. Such pipe and tube isintended for use in structural applicati
4、ons such as highway andbridge rails, chain-link fence posts, handrails, sign structures,awning supports, lighting brackets, etc. Structural pipe andtube is not intended for fluid-carrying applications involvingpressure.NOTE 1For drawn seamless tube used in pressure applications seeSpecifications B 2
5、10 and B 210M, for seamless pipe and seamlessextruded tube used in pressure applications see Specifications B 241/B 241M, and for drawn tube and pipe for general purpose applications seeSpecification B 483/B 483M.1.2 Alloy and temper designations are in accordance withANSI H35.1. The equivalent Unif
6、ied Numbering System alloydesignations are those of Table 1 preceded by A9, for example,A96061 for alloy 6061 in accordance with Practice E 527.1.3 For acceptance criteria for inclusion of new aluminumand aluminum alloys in this specification, see Annex A2.1.4 UnitsThe values stated in either inch-p
7、ound units orSI units are to be regarded separately as standard. SI units areshown in brackets. The values stated in each system may not beexact equivalents; therefore each system shall be used inde-pendently of the other. Combining values from the two systemsmay result in non-conformance with the s
8、pecification.1.4.1 While this standard is a combined SI and inch-poundstandard, standard pipe sizes are not applicable to SI units,therefore non-rationalized SI units (soft conversions) areshown for reader convenience. Rationalized hard convertedSI units are shown in brackets while non-rationalized
9、(softconverted) SI units are shown in parentheses.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use.

46、 alloy,temper, and nominal dimensions traceable to a heat-treat lot orlots, and subjected to inspection at one time.8. Chemical Composition8.1 Limits:8.1.1 The material shall conform to the chemical composi-tion limits prescribed in Table 1. The producer shall determineconformance by analyzing sampl
47、es taken when the ingots arepoured, or analyzing samples taken from the finished orsemi-finished product. If the producer has determined thechemical composition of the material during the course ofmanufacture, he shall not be required to sample and analyze thefinished product.NOTE 2It is standard pr
48、actice in the North American aluminumindustry to determine conformance to the chemical composition limitsprior to further processing of ingots into wrought products. Due to thecontinuous nature of the process, it is not practical to keep a specific ingotanalysis identified with a specific quantity o
49、f finished material.8.2 Number of SamplesThe number of samples taken fordetermination of chemical composition shall be as follows:8.2.1 When samples are taken at the time the ingots arepoured, at least one sample shall be taken for each group ofingots poured simultaneously from the same source of moltenmetal.8.2.2 When samples are taken from the finished or semi-finished product, a sample shall be taken to represent each4000 lb (1814 kg), or fraction thereof, of material in the lot,except
