35、e 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 subseq

36、uent 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: EN 754-1:20

37、16 (E) DIN EN 754-1:2016-10 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 no

38、t made 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 oval

39、ity 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) tole

If the purchaser wishes to inspect the product at the manufacturers works

45、, 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 specified in EN 573-3. If the purchaser requires closer limits for elements than those specified in the above standard, these

46、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 with those specified in EN 754-2 or those agreed between supplier and purchaser and stated in the order document. Typi

47、cal Brinell hardness values are given in EN 754-2, but they are not binding for acceptance purposes.

EN 754

48、-1:2016 (E) DIN EN 754-1:2016-10 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

49、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. For products intended for surface treatment, the superficial defects (discolouration, mechanical or structural) shall not be so exten
