30、 The purchaser should state when ordering the intended use and any further processing envisaged. The order shall describe the slug in the condition of delivery. If preformed slugs are required, the type of preforming shall be given when ordering, together with a drawing speci-fying the details. 4.2

31、Designation 4.2.1 Standard designation The standard designation shall be given in the following order: the designation of product (slug); the number of this European Standard (EN 570); the designation of the aluminium or aluminium alloy, see 5.2; the slug shape, e.g. flat, round with or without hole

The tolerances

38、specified in Tables 1 to 5 shall apply for slugs after punching or cutting in the bright condition. The tolerances on dimensions for slugs with a roughened surface shall be agreed between supplier and purchaser, as an increase of the outside diameters is to be expected. This increase in dimensions h

39、as to be taken into account by the supplier in his manufacturing process. The increase in dimensions depends on the material used, the mass of the slug and the method of roughing.

40、its in the manufacture of punched slugs: a) In the case of round slugs, the thickness should not exceed the diameter. b) In the case of rectangular slugs, the thickness should not exceed the width. c) In the case of slugs with a centre hole, the slug thickness should not exceed the hole diameter. If

41、 these limits are exceeded, slugs should be manufactured by cutting. 5.1.2 Slug diameter The tolerances specified in Table 1 for punched round slugs shall apply. For sawn round slugs the tolerances on diameter as specified in EN 755-3 shall apply. If tighter tolerances are needed, this shall be spec

42、ified in the order. In this case tolerances as specified in EN 754-3 shall apply.

43、circularity tolerance. 5.1.3 Hole diameter of punched slugs The tolerances specified in Table 2 shall apply only for flat slugs with a hole, with the hole diameter not exceeding 40 % of the slug diameter and the slug thickness not exceeding two thirds of the hole diameter. In all other cases, the to

44、lerances of the hole diameter shall be agreed between supplier and purchaser.
