Part 2: Mechanical properties.
This BS/EN 755-2 specifies the mechanical property limits resulting from tensile testing applicable to aluminium and aluminium alloy extruded rod/bar, tube and profIle.
Technical conditions for inspection 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 documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. 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 and delivery

3 Mechanical property limits
3.1 General
The mechanical properties shall be in conformity with those specified in Table 1 to Table 61 or those agreed upon between supplier and purchaser and stated in the order document.
Table Ito Table 61 contain limits of mechanical property values obtained by tensile testing according to EN ISO 6892-1 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 properties of test pieces taken in other directions can differ froni those for the longitudinal direction quoted in this standard.
Brinell hardness values given in Table 1 to Table 61 expressed as HBW values are for information only.
3.2 Elongation
If not otherwise agreed, theA value shall be used.
The A value for elongation is the % elongation measured over a gauge length of 5,65J (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 on A 50mm. Consequently, values for the Amm are included in the following tables.
The Aomm 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 755-2-2016 pdf download.
