21、2003 0 Introduction This standard is part of the series of EN metallic material standards for aerospace applications. The general organization of this series is described in EN 4258. This standard has been prepared in accordance with EN 4500-2. 1 Scope This standard specifies the requirements relati
22、ng to : Aluminium alloy AL-P7075- T73511 Extruded bar and section a or D 150 mm with peripheral coarse grain control for aerospace applications. This standard 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.
23、 2 Normative references This Standard incorporates by dated or undated reference provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of an
24、y of these publications apply to this Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.
