BS EN 755-2:2008 -,-,- EN 755-2:2008 (E) 5 1 Scope This document specifies the mechanical property limits resulting from tensile testing applicable to aluminium and aluminium alloy extruded rod/bar, tube and profile. Technical conditions for inspec
22、tion and delivery, including product and testing requirements, are specified in EN 755-1. Temper designations are defined in EN 515. The chemical composition limits for these materials are given in EN 573-3. 2 Normative references The following referenced documents are indispensable for the applicat
23、ion of this document. For dated references only the edition cited applies. For undated references the latest edition of the referenced document (including any amendments) applies. EN 755-1, Aluminium and aluminium alloys Extruded rod/bar, tube and profiles Part 1: Technical conditions for inspection
24、 and delivery EN 10002-1, Metallic materials Tensile testing Part 1: Method of test at ambient temperature 3 Mechanical property limits 3.1 General The mechanical properties shall be in conformity with those specified in Tables 1 to 57 or those agreed upon between supplier and purchaser and stated i
25、n the order document. Tables 1 to 57 contain limits of mechanical property values obtained by tensile testing according to EN 10002- 1 after sampling and test piece preparation according to EN 755-1. NOTE The mechanical properties refer to test pieces taken in the longitudinal direction. Mechanical
26、properties of test pieces taken in other directions can differ from those for the longitudinal direction quoted in this standard. Brinell hardness values given in Tables 1 to 57 expressed as HBW values are for information only. 3.2 Elongation If not otherwise agreed, the A value shall be used. The A
27、 value for elongation is the % elongation measured over a gauge length of 0 65, 5S (where S0 is the initial cross-sectional area of the test-piece), and expressed in percent. For certain products the supplier may choose (if not otherwise specified in the order documents) to use the elongation based
28、on A50mm. Consequently values for the A50mm are included in the following tables. The A50mm value is the elongation measured over a gauge length of 50 mm and expressed in percent. Test pieces and their location in the specimen are given in EN 755-1. BS EN 755-2:2008 -,-,- EN 755-2:2008 (E) 6 3.3 Ref
