20、cesPage 3 EN 485-4 : 1993 1 Scope This Part of EN 485 specifies tolerances on shape and di- mensions for wrought aluminium and aluminium alloy sheet, strip and plate obtained by cold-rolling, for general engineering applications. It applies to products with a thickness over 0,20 mm up to and includi
21、ng 50 mm. It does not apply to semi-finished products in coiled form to be subjected to further rolling (reroll stock), or to special productssuch as corrugated, embossed sheet and strip, or to special applications such as aerospace, can stock etc. which are dealt with in separate European Standards
22、. Technical delivery conditions for products covered by this standard are specified in EN 485-1. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These nor- mative references are cited at the appropriate places in the text
23、 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 un- dated references, the latest edition of the publication re- ferred to ap
24、plies. EN 485-1 Aluminium and aluminium alloys; sheet, strip and plate. Part 1 : Technical conditions of in- spection and delivery EN 573-3 Aluminium and aluminium alloys; chemical composition and form of wrought products. Part 3: Chemical composition 3 Dimensional tolerances 3.1 Thickness 3.1.1 For
25、 the purposes of this European Standard, the alloys are divided into two groups which correspond to varying difficulty when manufacturing the products. Closer thickness tolerances apply to group I alloys (soft alloys). The grouping is carried out according to the specified chemical composition limit
26、s of the alloys (see EN 573-3) as follows: Group I alloys: - 1 O00 series alloys; - non heat-treatable 7000 and 8000 series alloys; - 4000 series alloys with less than 2% maximum specified silicon content; - 3000 and 5000 series alloys for which the maximum specified magnesium and manganese contents
27、 are each not greater than 1.8 % and their sum not greater than 2,3 %. Group II alloys: The split into group I and group II of the most commonly used general engineering alloys is given in Annex A (see table A.l). - all alloys which do not belong to group I. 3.1.2 Thickness tolerances for sheet, str
28、ip and plate are specified in table 1. 3.1.3 Other thickness tolerances may be agreed between supplier and purchaser. They are specified in Annex B. 3.2 Width 3.2.1 Width tolerances for strip are specified in table 2. 3.2.2 Width tolerances for sheet and plate are specified in table 3. 3.3 Length 3.
29、3.1 Length tolerances for strip are not specified. 3.3.2 Length tolerances for sheet and plate are specified in table 4. 4 Shape tolerances 4.1 Lateral curvature 4.1.1 Lateral curvature tolerances for strip with a width up to and including 3500 mm are specified in table 5. The deviation from straigh
30、tness, d, is measured as indi- cated in figure 1, for a length, L, of 2000 mrn, from one end of the strip, while the strip is resting on a horizontal base- plate. 4.1.2 Lateral curvature tolerances for sheet and plate are specified in table 6. The deviation from straightness, d, is measured as indi-
31、 cated in figure 1, while the sheet or plate is resting on a horizontal baseplate. 4.2 Flatness 4.2.1 Flatness tolerances for strip are not specified. 4.2.2 Flatness tolerances for sheet and plate are speci- fied in table 7 and are expressed as a percentage of the length, L, and/or the width, W, and
32、/or the measured chord length, 1. Deviation from flatness, d, resulting from arching, buckling or egde waves, is measured as shown in figures 2 to 5, using a lightweight straightedge and a feeler gauge, dial gauge or scale, while the sheet or plate is resting on a horizontal baseplate, with its conc
33、ave side facing up- wards. These tolerances do not apply to sheet and plate supplied in the O (annealed) or F (asfabricated) tempers, or to bright sheet. These tolerances do not include end or corner turn-up. 4.3 Squareness 4.3.1 Squareness tolerances for strip are not specified. 4.3.2 Squareness to
34、lerances for sheet and plate are specified in table8. The squareness tolerance is ex- pressed as the maximum allowable difference in length of diagonals AA and BB as shown in figure 6.
