This European Standard
17、shall be given the 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of an identical text or by endorsement, at the latest by January 1999, and conflicting national standards shall be withdrawn at the latest by January 1999. According to the CEN/CENELEC Internal Regulations, the national standard
18、s organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. This standard
19、is part of a series of two standards.

21、ot or cold rolled strip in aluminium and aluminium alloy is to be rolled to thinner gauges in order to obtain cold rolled products such as sheets, strips, finstock and foil, this intermediate product is then called reroll stock. As the properties of the final products depend on the properties of the
22、 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 to be established carefully between producer and purchaser prior to orde
23、ring. 1 Scope This part of EN 12482 specifies the particular requirements for wrought aluminium and aluminium alloys in the form of cold rolled strip. The thickness range covered is over 0,20 mm to 4 mm. It does not apply to cold rolled strip which is not rerolled, such as strip for general engineer
24、ing 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 and the publications are listed hereafter. For dated references, subse
25、quent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.
