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

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

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

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

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
