30、he purposes of this document, the terms and definitions given in EN 12258-1:2012 and the following apply. 3.1 order document document or set of documents agreed between supplier and purchaser at the time of ordering SOURCE: EN 13957:2008, 3.1 4 Ordering information The order document shall contain t
31、he following: a) form and type of product: 1) form of the product (cold drawn rod/bar or tube). If tube, whether seamless or porthole/bridge; 2) reference to EN 573-3 for chemical composition limits; 3) reference to EN 515 for temper designation; 4) purchaser application, in particular whether subse
32、quent anodising is intended. This shall be clearly stated on the order document; b) reference to EN 754-2 for mechanical property limits; c) a reference to this document (EN 754-1); d) dimensions and shape of the product: 1) round tube: i) length; and only two of the following dimensions: BS EN 754-
33、1:2016EN 754-1:2016 (E) 6 ii) outside diameter; iii) inside diameter; iv) the tolerances for outside or inside diameter shall state as to whether the proposed tolerances are mean or inclusive of ovality (i.e. the maximum allowable deviation at any point from the specified diameter. If this is not ma
34、de clear on the order, then the supplier shall assume that the specified tolerances for either or both outside and inside diameters are inclusive of ovality. However, if the purchaser specifically requires that the outside and/or inside diameter tolerances must be both mean and inclusive of ovality
35、then this shall be clearly stated on the order; v) wall thickness; 2) round bar: i) diameter; ii) length; 3) square and hexagonal bar: i) width across flats; ii) length; 4) rectangular bar: i) width; ii) thickness; iii) length; 5) all other cases: i) drawing of cross section; ii) length; e) toleranc

38、 A value for elongation; i) for products intended to be anodised by the purchaser, the order document shall also contain the information about the intended particular surface treatment with reference to the relevant European Standard. 5 Requirements 5.1 Production and manufacturing processes Unless
39、otherwise specified in the order document, the production and manufacturing processes shall be left to the discretion of the manufacturer. Unless it is explicitly stated in the order document, no obligation shall be placed on the manufacturer to use the same processes for subsequent or similar order
40、s. 5.2 Quality control The supplier shall be responsible for the performance of all inspection and tests required by the relevant European Standard and/or the particular specification prior to shipment of the product. If the purchaser wishes to inspect the product at the manufacturers works, he shal
41、l notify the supplier at the time of placing the order. 5.3 Chemical composition limits The chemical composition limits shall be in conformity with the requirements specified in EN 573-3. If the purchaser requires closer limits for elements than those specified in the above standard, these limits sh
42、all be according to an agreement between supplier and purchaser and stated in the order document. 5.4 Mechanical properties The mechanical properties shall be in conformity with those specified in EN 754-2 or those agreed between supplier and purchaser and stated in the order document. Typical Brine
43、ll hardness values are given in EN 754-2, but they are not binding for acceptance purposes. However, a Brinell hardness value may be agreed upon for acceptance testing. 5.5 Freedom from surface defects The surface shall be free from defects prejudicial to its suitable and proper use. BS EN 754-1:201
44、6EN 754-1:2016 (E) 8 The product shall have a smooth and clean surface. However, small surface defects such as light scratches, indentations, laminations, discolouration and non-uniform surface appearance resulting from heat-treatment, etc., which cannot always be totally avoided, are generally perm
45、itted on the product surface. Whilst an operation designed to mask a fault is not permitted, the elimination of a superficial fault is permissible provided that the dimensional tolerances and material properties continue to meet the specification. For products intended for surface treatment, the sup
46、erficial defects (discolouration, mechanical or structural) shall not be so extensive as to impair the decorative appearance of the surface after the agreed surface treatment. Limiting samples may be agreed between supplier and purchaser. 5.6 Tolerances on dimensions and form For the different forms
47、 of products, if not otherwise agreed between supplier and purchaser, the tolerances on dimensions and form shall be in conformity with the relevant European Standards EN 754-3, EN 754-4, EN 754-5, EN 754-6, EN 754-7 and EN 754-8. Unless otherwise agreed, the purchaser may reject only those products
48、 having dimensions not complying with the specified tolerances. 5.7 Stress corrosion cracking resistance The products of alloy EN AW-7075, in tempers T73, T7351, T73510 and T73511, for thicknesses equal to or greater than 20 mm, shall exhibit no evidence of stress corrosion cracking when tested in a
49、ccordance with ASTM G47 or ISO 9591 in the transverse direction at a stress level of 75 % of the specified Rp0,2. If such testing is required this has to be specified in the order document. 5.8 Additional requirements Any additional requirements shall be agreed between supplier and purchaser and stated in the order document. 6 Test procedures 6.1 Sampling 6.1.1 Samples for chemical analysis Sampling shall be carried out at the time of casting according to EN 14361.
