8、with the rules of AECMA-STAN defined in AECMA- STANS General Process Manual, this standard has received approval for Publication. Page 3 prEN 2632:2003 O Introduction This standard is part of the series of EN metallic material standards for aerospace applications. The general organization of this se
9、ries is described in EN 4258. This standard has been prepared in accordance with EN 4500-2. 1 Scope This standard specifies the requirements relating to: Aluminium alloy AL-P7075- T73511 Extruded bar and section a or D 5 150 mm with peripheral coarse grain control for aerospace application. This sta
10、ndard may also be used to supply material in the T73510 condition if specified by the purchaser on the order and the product is marked accordingly. 2 Normative references This European Standard incorporates by dated or undated reference provisions from other publications.
