19、 European Standard specifies the particular requirements for wrought aluminium and aluminium alloys in the form of circle or circle stock for general applications. It applies to: Circles made out of hot or cold rolled circles stock by: Blanking: thickness 0,2 mm up to including 12 mm and with a diam

20、eter up to 1 000 mm; Sawing or shearing: thickness 0,2 mm up to and including 200 mm with a diameter up to 3 500 mm; Hot or cold rolled circle stock with a thickness from 0,2 mm up to and including 200 mm and with a width up to 3 500 mm. It does not apply to slugs for impact extrusions or to circle

21、and circle stock for culinary utensils applications which are dealt with in other European Standards. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cit

22、ed applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

33、conform to Table 1. These tolerances include the tolerances on roundness. NOTE For circle obtained by blanking the recommended standard diameters are: From 100 mm up to 500 mm nominal diameter: every multiple of 5; Over 500 mm up to 1 000 mm nominal diameter: every multiple of 10. 6.3 Thickness Tole

34、rances on thickness for hot rolled circle and circle stock shall conform to Table 2. They are identical to those specified in Table 1 of EN 485-3:2003 and are reproduced here for convenience. The tolerances on thickness for cold rolled circle and circle stock shall conform to Table 3. They are ident

35、ical to those specified in Table 1 of EN 485-4:1993 and are reproduced here for convenience. The partition into group I and group II of most common materials which may be used for the present application shall be as shown in Table 4. 6.4 Tolerances on flatness for circles Tolerances on flatness for

36、circles, expressed as a percentage of the diameter D and/or the measured chord length L, shall conform to Table 5. Deviation from flatness d, resulting from arching or buckling, shall be measured as shown in Figures 1 and 2, using a lightweight straightedge and a feeler gauge, dial gauge or scale, w

37、hile the circle is resting on a horizontal base plate, concave side upwards. Two measurements shall be carried out with the straight edge respectively parallel and perpendicular to the rolling direction.
