40、 5 Information to be supplied by the purchaser 5.1 Mandatory information The purchaser shall select the steel type, the shape and dimensions of the forging taking the intended use into account. The purchaser shall provide in the purchase order all the information necessary for describing the forging
41、 and its characteristics and details concerning delivery including the following: a) the quantity of forgings required; b) the forging dimensions, or the drawing number(s) containing the dimensions, tolerances and surface finish, to which the forgings shall conform; c) the steel designation of the m
42、aterial of which the forgings are made (see Clause 4); d) whether the purchaser needs to be informed of the forging procedure (see 7.2); e) whether production and testing of the forgings is to be witnessed by the purchasers representative, and if so, the particular stages in production and testing a
43、t which the purchasers representative may require to be present (see Clause 15); f) any required options (see 5.2 and Annex A); g) whether additional sample material is required for welding tests, the dimensions and location of such test pieces being agreed with the manufacturer; h) the type of insp
44、ection document in accordance with EN 10204. 5.2 Options A number of options are available and these are detailed in Annex A. Where any of the options given are specified at the time of the order, the forgings shall conform to the requirements of any such option, in addition to the mandatory require
45、ments of this Part of this European Standard. If the purchaser does not specify any options at the time of enquiry and order, the manufacturer shall supply in accordance with the basic specification.

46、hall be produced by an electric process or one of the basic oxygen processes (see A.1). 6.2 Deoxidation The steel shall be fully killed. 7 Manufacture of the product 7.1 Hot working The choice of hot working process shall be at the discretion of the manufacturer (see A.2). 7.2 Forging reduction The
47、forging shall receive a sufficient forging reduction to completely consolidate the forging and remove the cast structure (see A.3). 7.3 Heat treatment The forgings shall be heat treated as specified in the relevant Part of EN 10222, unless otherwise agreed at the time of enquiry and order. 7.4 Welda
48、bility The steels in this European Standard are generally regarded as being weldable. Welding shall be carried out in accordance with EN 287 and EN 288. 8 Surface condition and soundness 8.1 General The forgings shall be sound and free from defects that preclude their intended use (see also A.4, A.5
49、, A.6 and A.7). 8.2 Removal of surface defects 8.2.1 Conformity to 8.1 Before the forgings are despatched or presented for acceptance, surface defects shall be removed in order to conform to 8.1. 8.2.2 Chipping and/or grinding Surface defects shall be removed by chipping and/or grinding providing the residual thickness meets the minimum tolerance and that the resulting depression does not undercut t
