Anotace textu normy ASTM B221-21 :
This specification covers extruded bars, rods, wires, profiles, and tubes made from aluminum and aluminum alloys. All the products should be produced by hot extrusion or similar methods. The chemical composition of each material is determined in accordance with the specified suitable chemical and spectrochemical test methods. Samples for chemical analysis should be taken when the ingots are poured or from the finished or semi-finished products by drilling, sawing, milling, turning, or clipping. Tensile properties, elongation, and yield strengths of each product should conform to the requirements listed herein. Elongation requirements are not applicable for materials with sizes smaller than the specified limits.
Keywords:

1.1?This specificationNote 1:?Throughout this specification, the use of the term Note 2:?For rolled or cold-finished bar and rod refer to Specification B211/B211M, for drawn seamless tube used in pressure applications, Specification B210/B210M, for structural pipe and tube, Specification B429/B429M, and for seamless pipe and tube used in pressure applications, Specification B241/B241M. Note 3:?Pipe and tube products listed in this specification
are intended for general purpose applications. This specification
may not address the manufacturing processes, integrity testing, and
verification required for fluid-carrying applications involving
pressure. See Specifications B210/B210M or B241/B241M, or both as appropriate, for
seamless pipe and tube used in fluid-carrying applications
involving pressure. See Specification B234, as appropriate, for use in surface
condensers, evaporators, and heat exchangers.
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 1100 in accordance with Practice E527. 1.3?For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2. 1.4?A complete metric companion to Specification B221 has been developedSpecification B221M; therefore, no metric equivalents are presented in this specification. 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. |
