Metallic Material Domain I I Copyright 2003 O by AECMA-STA1 Page 2 prEN 4202: 2003 Foreword This standard was reviewed by the Domain Technical Coordinator of AECMA-STANS Metallic Material Domain. After inquiries and votes carried out in accordance with the
6、rules of AECMA-STAN defined in AECMA- STANS General Process Manual, this standard has received approval for Publication. Page 3 prEN 4202: 2003 O Introduction This standard is part of the series of EN metallic material standards for aerospace applications. The general organization of this series is
7、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-P6082- T651 Plate 6 mm a 25 mm for aerospace application. 2 Normative references This European Standard incorporates by dated or undate
