15、ument (EN 570:2007) has been prepared by Technical Committee CEN/TC 132 “Aluminium and aluminium alloys”, the secretariat of which is held by AFNOR.

16、 July 2007, and conflicting national standards shall be withdrawn at the latest by July 2007. This document supersedes EN 570:1994. Within its programme of work, Technical Committee CEN/TC 132 entrusted CEN/TC 132/WG 11 “Slugs for impact extrusion“ to revise EN 570:1994. The following technical modi
17、fications have been introduced during the revision: Clause 2: References to EN 754-3, EN 754-7, EN 754-8, EN 755-3, EN 755-7 and EN 755-8 added; Clause 4: Text modified; Clause 5: Text in 5.1.1 modified, former Table 2 deleted and replaced by reference to EN 755-3, former Table 4 deleted and replace
18、d by references to EN 755-7 and EN 755-8; Table 6: Materials EN AW-1090, EN AW-1100, EN AW-3003, EN AW-5251, EN AW-6005A and EN AW-6063 added; materials EN AW-5305, EN AW-5505 and EN AW-5110 deleted. Attention is drawn to the possibility that some of the elements of this document may be the subject
19、of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. CEN/TC 132 affirms it is its policy that in the case when a patentee refuses to grant licences on standardised standard products under reasonable and not discriminatory conditions then this product sha
20、ll be removed from the corresponding standard. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following coun- tries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Den- mark, Estonia, Finland, France,

32、election of material and of the condition of supply is at the purchasers discretion. 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
33、 shall be given when ordering, together with a drawing speci- fying the details. 4.2 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 alumini
34、um or aluminium alloy, see 5.2; the slug shape, e.g. flat, round with or without hole, rectangular, preformed; dimensions in millimetres; the surface finish, see 5.4.2. 4.2.2 Examples of standard designation 4.2.2.1 Round slug without a centre hole (see Figure 1) Description of product, EN number, m

40、 4 sc 5 Requirements 5.1 Tolerances on dimensions and form 5.1.1 General The requirements for tolerances on dimensions and form for slugs manufactured in a flat or preformed shape are specified in 5.1.2 to 5.1.6. The tolerances specified in Tables 1 to 5 shall apply for slugs after punching or cutti
41、ng 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 has to be taken into account by the supplier in his manufacturing process
42、. The increase in dimensions depends on the material used, the mass of the slug and the method of roughing.

43、rking permitted without license from IHS -,-,- EN 570:2007 (E) 7 Limits 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 cen
44、tre hole, the slug thickness should not exceed the hole diameter. If 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
45、-3 shall apply. If tighter tolerances are needed, this shall be specified in the order. In this case tolerances as specified in EN 754-3 shall apply.

47、exceeding two thirds of the hole diameter. In all other cases, the tolerances of the hole diameter shall be agreed between supplier and purchaser.
