2、tiques mcaniques Aluminium und Aluminiumlegierungen - Bnder, Bleche und Platten - Teil 2: Mechanische Eigenschaften This European Standard was approved by CEN on 29 August 2008. CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this E
3、uropean Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN Management Centre or to any CEN member. This European Standard exists in three official versions (En
4、glish, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN Management Centre has the same status as the official versions. CEN members are the national standards bodies of Austria, Belgium, Bulgar

This European Standard shall be given the status of a n
9、ational standard, either by publication of an identical text or by endorsement, at the latest by April 2009, and conflicting national standards shall be withdrawn at the latest by April 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of paten
10、t rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. CEN/TC 132 affirms it is its policy that in the case when a patentee refuses to grant licences on standardised standard products under reasonable and not discriminatory conditions, then this pro
11、duct shall be removed from the corresponding standard. This document supersedes EN 485-2:2007. Within its programme of work, Technical Committee CEN/TC 132 entrusted CEN/TC 132/WG 7 “Sheets, strips and plates“ to revise EN 485-2:2007. EN 485 comprises the following parts under the general tittle, “A
12、luminium and aluminium alloys Sheet, strip and plate“: Part 1: Technical conditions for inspection and delivery Part 2: Mechanical properties Part 3: Tolerances on dimensions and form for hot-rolled products Part 4: Tolerances on shape and dimensions for cold-rolled products The following changes ha
13、ve been made: In all tables, the tempers have been separated in rows. Table 25: Values for temper H112 have been modified. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgiu

15、1 Scope This European Standard specifies the mechanical properties of wrought aluminium and wrought aluminium alloy sheet, strip and plate for general engineering applications. It does not apply to semi-finished rolled products in coiled form to be subjected to further rolling (reroll stock) or to s
16、pecial products such as corrugated, embossed, painted, sheets and strips or to special applications such as aerospace, can stock, finstock, for which mechanical properties are specified in separate European Standards. The chemical composition limits of the alloys are specified in EN 573-3. Temper de
17、signations are defined in Annex B, in compliance with the provisions of EN 515. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the re
18、ferenced document (including any amendments) applies.

20、s The mechanical properties shall be in conformity with those specified in Clause 4 or those agreed upon between purchaser and manufacturer and stated on the order document. 4 List of alloys with mechanical property limits 4.1 General Tables 1 to 46 contain mechanical property limits values obtained
21、 by tensile testing according to EN 10002-1 after sampling and after sample preparation according to EN 485-1. They also contain values of bend radius and hardness following sampling and test methods as described in EN 485-1. These values are for information only. For some alloys they contain provis
