It

    29、applies to products with a thickness over 0,20 mm up to and including 50 mm. It does not apply to semi-finished rolled products in coiled form to be subjected to further rolling (rerollstock) or to special products such as corrugated, embossed, etc. sheet and strip or to special applications such as

    30、 aerospace, can stock, etc. which are dealt with in separate European Standards. Technical conditions for inspection and delivery of products covered by this standard are specified inEN485-1. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from ot

    31、her 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 any of these publications apply to this European Standard only when incorporated in it by amendment o

Tighter thickness tolerances apply to Group I alloys (soft al

    34、loys). The grouping is carried out according to the specified chemical composition limits of the alloys (see EN 573-3) as follows: Group I alloys: 1000 series alloys; non heat-treatable7000 and8000 series alloys; 4000 series alloys with less than2% maximum specified silicon content; 3000 and 5000 se

    35、ries alloys for which the maximum specified magnesium and manganese contents are each no greater than1,8% and their sum no greater than2,3%. Group II alloys: all alloys which do not belong to Group I. The split into Group I and Group II of the most commonly used general engineering alloys is given i
