35、s agreed between supplier and purchaser at the time of ordering 4 Ordering information The order document shall contain the following: a) form and type of product: 1) form of the product (extruded rod/bar, tube or profile). If tube, whether seamless or porthole/bridge extruded, 2) reference to EN 57
36、3-3 for chemical composition limits, 3) reference to EN 515 for temper designation, 4) purchaser application, in particular whether subsequent anodizing is intended. This shall be clearly stated on the order document; b) reference to EN 755-2 for mechanical property limits; c) reference to this docu
37、ment (EN 755-1); d) dimensions and shape of the product: 1) round tube: i) length, BS EN 755-1:2016EN 755-1:2016 (E) 7 and only two of the following dimensions: ii) outside diameter, iii) inside diameter, The tolerances for inside and outside diameter shall state as to whether the proposed tolerance
38、s are mean or inclusive of ovality (ie the maximum allowable deviation at any point from the specified diameter). If this is not made clear on the order, the supplier shall assume that the specified tolerances for either or both outside and inside diameters are inclusive of ovality. However, if the
39、purchaser specifically requires that the outside and/or inside diameter tolerances are to be both mean and inclusive of ovality, then this shall be clearly stated on the order, iv) wall thickness; 2) round bar: i) diameter, ii) length; 3) square and hexagonal bar: i) width across flats, ii) length;
40、4) rectangular bar: i) width, ii) thickness, iii) length; 5) all other cases: i) drawing of cross section, ii) length; e) tolerances on dimensions and form, with reference to the appropriate European Standard and/or a drawing; f) quantity: 1) mass, 2) number of pieces, 3) total length, 4) tolerance

42、 surface finish requirements, 5) surface protection, 6) packaging, 7) inspection prior to delivery, 8) use of A50mmvalue instead of A value for elongation; i) for products intended to be anodized by the purchaser, the order document shall also contain the information about the intended particular su
43、rface treatment with reference to the relevant European Standard. 5 Requirements 5.1 Production and manufacturing processes Unless 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
44、 in the order document, no obligation shall be placed on the manufacturer to use the same processes for subsequent similar orders. 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 sp
45、ecification prior to shipment of the product. If the purchaser wishes to inspect the product at the manufacturers works, he shall 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 specifi
46、ed in EN 573-3. If the purchaser requires closer limits for elements than those specified in the above standard, these limits shall 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
47、 with those specified in EN 755-2 or those agreed between supplier and purchaser and stated in the order document. Typical Brinell hardness values are given in EN 755-2, but they are not binding for acceptance purposes. However, a Brinell hardness value may be agreed upon for acceptance testing. BS

The product shall have a smooth and clean surface. However, small surface defects such as light scratches, indentations, laminations, discolou
49、ration and non-uniform surface appearance resulting from heat-treatment, etc., which cannot always be totally avoided, are generally permitted 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. Visible surfaces and surfaces which will be subject to a surface treatment shall be indic
