36、haser at the time of ordering 4 Ordering information The order document shall contain the following: a) form and type of product: form of the product (cold drawn rod/bar or tube). If tube, whether seamless or porthole/bridge, reference to EN 573-3 for chemical composition limits, reference to EN 515
37、 for temper designation, purchaser application, in particular whether subsequent 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)
38、round tube: length, and only two of the following dimensions: outside diameter, inside diameter, wall thickness; 2) round bar: diameter, length; BS EN 754-1:2008Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 16/07/2008 08:28, Uncontrolled Copy, (c) BSIEN 754-1:2008 (E) 7 3) square and hexago
39、nal bar: width across flats, length; 4) rectangular bar: width, thickness, length; 5) all other cases: drawing of cross section, length; e) tolerances on dimensions and form, with reference to the appropriate European Standard and/or a drawing; f) quantity: mass, number of pieces, total length, tole
40、rance on quantity; g) any requirements for inspection documents; h) any special requirements agreed between supplier and purchaser: marking of products, reference to drawings, part numbers, etc, additional or special testing, e.g. stress corrosion testing, surface finish requirements, surface protec
41、tion, packaging, inspection prior to delivery, use of A50mmvalue instead of 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
42、Standard. BS EN 754-1:2008Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 16/07/2008 08:28, Uncontrolled Copy, (c) BSIEN 754-1:2008 (E) 8 5 Requirements 5.1 Production and manufacturing processes Unless otherwise specified in the order document, the production and manufacturing processes shal
43、l 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 orders. 5.2 Quality control The supplier shall be responsible for the performance of all inspec
44、tion 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 shall notify the supplier at the time of placing the order. 5.3 Chemical composition limits Th
45、e 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 shall be according to an agreement between supplier and purchaser and stated in the order do
46、cument. 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 Brinell hardness values are given in EN 754-2, but they are not binding for acceptance purposes
47、. 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. The product shall have a smooth and clean surface. However, small surface defects such as light scratches
48、, indentations, laminations, discolouration 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
49、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 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
