BS EN 755-2:2016 pdf free.Aluminium and aluminium alloys一Extruded rod/bar, tube and profiles Part 2: Mechanical properties.
This European Standard 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.

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 from 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 5,65jj (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 Aonir,i. Consequently, values for the A5Omm are included in the following tables.
The Aomm value is the elongation measured over a gauge length of 50 mm and expressed in percent.
