Within its programme of work, Techn
21、ical Committee CEN/TC 132 entrusted CEN/TC 132/WG 7 “Sheet, strip and plate” to work out the following standard: EN 485-4, “Aluminium and aluminium alloys Sheet, strip and plate Part 4: Tolerances on dimensions and form for cold-rolled products”. This standard is part of a set of four standards. The
22、 other standards deal with: EN 485-1, “Aluminium and aluminium alloys Sheet, strip and plate Part 1: Technical conditions for inspection and delivery”. EN 485-2, “Aluminium and aluminium alloys Sheet, strip and plate Part2:Mechanical properties”. EN 485-3, “Aluminium and aluminium alloys Sheet, stri

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 1994, and conflicting national standards shall be withdrawn at
24、the latest by April 1994. The Standard was approved and in accordance with the CEN/CENELEC Internal Regulations, the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norwa

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

33、oducts Part 3: Chemical composition. 3 Dimensional tolerances 3.1 Thickness 3.1.1 For the purpose of this European Standard the alloys are distributed into two groups which correspond to varying difficulty when manufacturing the products. 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
