This European Standard shall be given the status
12、of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2008, and conflicting national standards shall be withdrawn at the latest by September 2008. This document supersedes EN 485-1:1993. Within its programme of work, Technical committee CEN/
13、TC 132 entrusted CEN/TC 132/WG 7 “Sheets, strips and plates“ to revise EN 485-1:1993. EN 485 comprises the following parts under the general title “Aluminium and aluminium alloys Sheet, strip and plate“: Part 1: Technical conditions for inspection and delivery Part 2: Mechanical properties Part 3: T
14、olerances on dimensions and form for hot-rolled products Part 4: Tolerances on shape and dimensions for cold-rolled products Besides very slight additional adjustments in the text and update of normative references, the following technical changes have been made: Clause 1: thickness increased to 400
15、 mm; addition of Clause 6 (previously in EN 485-2); Clause 7 amended; addition of Claude 10; addition of Bibliography. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifyin

19、lloy sheet, strip and plate for general engineering applications. It also includes provision for ordering and testing. It applies to products with a thickness over 0,20 mm up to and including 400 mm. It does not directly apply to semi-finished rolled products in coiled form to be subjected to furthe
20、r rolling (reroll stock) or to special applications such as aerospace, can stock, finstock, etc. which are dealt with in separate European Standards. NOTE Most of these specific standards refer for some provisions to the present standard. 2 Normative references The following referenced documents are

29、urposes of this document, the terms and definitions given in EN 12258-1:1998 and the following apply. 3.1 sheet/plate flat rolled product of rectangular cross-section with uniform thickness between 0,20 mm and 6 mm for sheet or above 6 mm for plate, supplied in straight lengths (i.e. flat) usually w
30、ith trimmed or sawn edges NOTE 1 For sheet, the thickness does not exceed one-tenth of the width. NOTE 2 Corrugated, embossed (with patterns, for example grooves, ribs, checkers, tears, buttons, lozenges), coated, edge conditioned and perforated products in this general form when derived from sheet
31、as defined above are classified as sheet. NOTE 3 Flat sheets and plates material between 3 mm and 15 mm are sometimes called “shate“. 3.2 strip flat rolled product of rectangular cross-section with uniform thickness over 0,20 mm, supplied in coils usually with trimmed edges NOTE 1 The thickness does
32、 not exceed one-tenth of the width. NOTE 2 Corrugated, embossed (with patterns, for example grooves, ribs, checkers, tears, buttons, lozenges), coated, edge conditioned and perforated products in this general form when derived from sheet as defined above are classified as sheet.

It shall have a
48、 smooth and clean surface. However small surface imperfections such as light scratches, indentations, laminations, stripes, roll marks, discolorations and non-uniform surface appearance resulting from heat-treatment, etc., which cannot always be totally avoided, are generally permitted on both sides
49、 of the product. Whilst an operation designed to mask a defect is not permitted, superficial defects may be eliminated, provided that the dimensional tolerances and material properties continue to meet the specifications.
