17、 3 EN 603-3 : 2000 1 Scope This part of EN 603 specifies the tolerances on dimensions and form of wrought aluminium and aluminium alloy forging stock. It applies to extruded and rolled products. 2 Normative references This standard incorporates, by dated or undated reference, provisions from other p
18、ublications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this standard only when incorporated in it by amendment or revision. Fo

24、 The chemical composition limits of the alloys shall be as specified in EN 573-3. 5.2 Alloy groups For the purposes of this part of this European Standard the alloys are divided into two groups which correspond to varying difficulty when manufacturing the extruded forging stock. The division into Gr
25、oup I and Group II of these alloys is specified in Table 1. The division into Class A and Class B alloys shall be as specified in EN 573-4. Class A covers aluminium and aluminium alloys produced in large volume as wrought forging stock for which mechanical properties are specified in EN 603-2. Class
26、 B covers aluminium and aluminium alloys produced in limited volume as wrought forging stock for which mechanical properties are not specified.

30、ified in EN 603-1. NOTE These products are normally supplied in the F temper as defined in EN 515. 6.2 Extruded round bar 6.2.1 Diameter Tolerances on diameter shall be as specified in Table 2. Tolerances on diameter can vary dependent on the method of extrusion (direct or indirect) and the type of
31、extrusion die used (single hole or multi hole). With Group II alloys closer tolerances are possible when the indirect method of extrusion is employed using either a single hole or multi hole die at the discretion of the supplier. In diameters up to and including 120 mm, however, the forging requirem
32、ent can demand restricted tolerances combined with a more uniform material structure obtainable only with the use of a single hole die. In such cases the purchaser shall specify this special requirement on the order. Table 2 - Tolerances on diameter Dimensions in millimetres Page 6 EN 603-3 : 2000 D

34、permissible ovality shall be 50% of the tolerance range specified in Table 2; e.g. for a diameter tolerance of i 0,22 mm, the maximum permissible ovality shall be 0,22 mm. 6.2.3 Length The tolerances on fixed length shall be as specified in Table 3. If fixed lengths are to be supplied, this shall be
35、 stated on the order. O If no fixed or minimum length is specified in the order, round extruded bars may be delivered in random lengths. The actual lengths and tolerances on random lengths shall be agreed between supplier and purchaser. 6.2.4 Perpendicularity of cut ends The maximum deviation from p
36、erpendicularity of cut ends shall be within half of the fixed length tolerance range (see Table 3) for both fixed and random lengths, e.g. for a tolerance on fixed length of +IO mm, the perpendicularity of cut ends shall be within 5 mm.

37、h, and h, shall be as specified in Table 4. They shall be measured as shown in Figure 1 with the bar placed on a horizontal baseplate so that its mass decreases the deviation.
