34、s given in EN 4259 apply. For definitions specific to steel, see EN 10079. 4 Wording of order The order shall clearly indicate: quantities to be supplied; dates of delivery; material standard number; delivery condition and metallurgical code of products; dimensions and tolerances or reference to an
35、appropriate dimensional standard; product designation, when required; forwarding address; nature and type of packing, if required; surface protection, if appropriate; definition and frequency of any special tests and their retest procedures, if required. 5 Health and safety Products in the delivery
36、condition shall fulfil the health and safety laws of the area of the country when and where it is to be delivered. A product safety data sheet shall be available. 6 Technical requirements 6.1 General The product shall satisfy the requirements of the order, drawing inspection schedule or material sta
37、ndard: see Table 2, line 5. The order, drawing or inspection schedule shall specify the tests to be performed upon (i) pre-forgings for qualification and/or requalification (ii) serial production forgings for process control testing (Procedure X: see 6.4) and (iii) batch release when cut-up testing
38、or forgings is required. Unless otherwise specified on the order, drawing or inspection schedule, acceptance criteria for the tests are stated in the material standard, 4) Published by: ASTM National (US) American Society for Testing and Materials http:/www.astm.org/ BS EN 4700-006:2010EN 4700-006:2

Table 2 related to lines 1 to 29 (inclusive) of the material standard and Table 3 relates to lines 30 onwards in which the subline format is also used. If a particular test is needed but
40、 not shown in a specific line in Tables 2 and 3, the requirement shall be specified on the order, drawing, inspection schedule or material standard. 6.2 Qualification requirements See line 100 in Table 3 of this technical specification. Qualification shall normally comprise assessment of pre-product
41、ion forgings. See Table 2, section 4.2. 6.3 Re-qualification requirements Re-qualification of serial production forgings may be required, in the following cases: modification of the drawing; use of forging stock from a different source; modifications to the forging stock form and/or manufacturer rou
42、te; modifications to an existing die; use of a new (replacement) die; modifications to the forging manufacturing route; when a significant time interval (usually several years) had elapsed between forging campaigns for a specific part number; when required by the purchaser for any other reason. Re-q
43、ualification testing requirements, especially location of test pieces, shall be identical to those used for the initial qualification of the pre-production forgings unless otherwise specified on the order, drawing or inspection schedule. 6.4 Release requirements Release testing shall be the responsi
44、bility of the manufacturer. The sampling procedure for release testing shall be one of the following, as specified on the order, drawing or inspection schedule. Where no procedure is specified, procedure A shall be used: BS EN 4700-006:2010EN 4700-006:2010 (E) 8 Procedure A: Separate forged test sam
45、ples shall be procedure produced from the same batch of forging stock as that used to make the serial production forgings. Procedure A may be used alone unless denoted AX on the drawing, order or inspection schedule in which case it shall be applied only in conjunction with procedure X (See 6.5). Pr
46、ocedure B: Separate forged heat treatment control test samples shall be prepared which conform to the same material standard as the production forgings, but from a different batch of forging stock. Procedure B shall only be used when full heat treatment of the serial production forgings is carried o
47、ut by the manufacturer and only in conjunction with procedure X (See 6.5). Procedure C: Integral test samples shall be removed from each forgings. The order, drawing of inspection schedule shall specify how many test samples shall be tested per batch. Procedure C may be used alone unless denoted CX
48、on the drawing, order or inspection schedule in which case it shall be applied only in conjunction with procedure X (See 6.5). Procedure D: Test samples shall be machined from forging(s) selected from each production batch and at locations specified on the order, drawing or inspection schedule. When
49、 required, the manufactured shall inform the purchaser of the planned dates for extraction of samples and release testing in order that these operations may be witnessed. 6.5 Process control testing (Procedure X) Procedure X is process control procedure consisting of periodic “cut-up” testing to ensure that the serial produc
