3、2.1. Scope*1.1 This specification covers aluminum-alloy extrudedstructural pipe and tube in those selected alloys shown in Table1 and tempers shown in Table 2, and in those standard sizesshown in Tables 3-5, as well as in other nonstandard sizes asagreed upon between the purchaser and supplier. Such
4、 pipe andtube is intended for use in structural applications such ashighway and bridge rails, chain-link fence posts, handrails,sign structures, awning supports, lighting brackets, etc. Struc-tural pipe and tube is not intended for fluid-carrying applica-tions involving pressure.NOTE 1For drawn seam
5、less tube used in pressure applications seeSpecifications B210 and B210M, for seamless pipe and seamless extrudedtube used in pressure applications see Specifications B241/B241M, andfor drawn tube and pipe for general purpose applications see SpecificationB483/B483M.1.2 Alloy and temper designations
6、 are in accordance withANSI H35.1/H35.1(M). The equivalent Unified NumberingSystem alloy designations are those of Table 1 preceded byA9,for example, A96061 for alloy 6061 in accordance withPractice E527.1.3 For acceptance criteria for inclusion of new aluminumand aluminum alloys in this specificati
7、on, see Annex A2.1.4 UnitsThe values stated in either inch-pound 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
8、from the two systemsmay result in non-conformance with the specification.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 con
9、vertedSI units are shown in brackets while non-rationalized (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. It is theresponsibility of the user of this standard to establish appro-priate safet
10、y and health practices and determine the applica-bility of regulatory limitations prior to use.2.
