This European Standard shall be given the

16、 status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 1999, and conflicting national standards shall be withdrawn at the latest by January 1999. This European Standard has been prepared under a mandate given to CEN by the European Comm

17、ission and the European Free Trade Association, and supports essential requirements of EU Directive(s). According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic,

18、Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. This standard is part of a series of two standards. The other standard deals with: EN 12482-2, Aluminium and aluminium alloys Reroll stock

21、 As the properties of the final products depend on the properties of the reroll stock and the further process, it is therefore not practicable to specify in detail minimum requirements for all properties of reroll stock. This standard therefore gives only guidelines to the specifications which have

22、 to be established carefully between producer and purchaser prior to ordering. 1 Scope This part of EN 12482 specifies the particular requirements for wrought aluminium and aluminium alloys in the form of hot rolled strip. The thickness range covered is from 2,0 mm to 12 mm. It does not apply to hot

23、 rolled strip which is not rerolled, such as strip for general engineering or special applications. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text

24、 and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies
