The or
32、der, 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 section 6.4) and (iii) batch release when cut-up testing or forgings is required. U
33、nless otherwise specified on the order, drawing or inspection schedule, acceptance criteria for the tests are stated in the material standard, the requirements for each line of which are detailed in Tables 2 and 3 of this technical specification. Table 2 related to lines 1 to 29 (inclusive) of the m
34、aterial standard and Table 3 relates to lines 30 onwards in which the subline format is also used. If a particular test is needed but 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
35、requirements See line 100 in Table 3 of this technical specification. Qualification shall normally comprise assessment of pre-production 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: modif
36、ication of the drawing; use of forging stock from a different source; modifications to the forging stock form and/or manufacturer route; modifications to an existing die; use of a new (replacement) die; modifications to the forging manufacturing route; when a significant time interval (usually sever
37、al years) had elapsed between forging campaigns for a specific part number; when required by the purchaser for any other reason. Re-qualification testing requirements, especially location of test pieces, shall be identical to those used for the initial qualification of the pre-production forgings un
38、less otherwise specified on the order, drawing or inspection schedule. 6.4 Release requirements Release testing shall be the responsibility 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
39、no procedure is specified, procedure A shall be used: prEN 4700-006:2009 (E) 7 Procedure A: Separate forged test samples 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 drawin
40、g, order or inspection schedule in which case it shall be applied only in conjunction with procedure X (See 6.5). Procedure 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 f
41、orging stock. Procedure B shall only be used when full heat treatment of the serial production forgings is carried out 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 sche
42、dule shall specify how many test samples shall be tested per batch. Procedure C may be used alone unless denoted CX 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(
43、s) selected from each production batch and at locations specified on the order, drawing or inspection schedule. When 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 c
44、ontrol testing (Procedure X) Procedure X is process control procedure consisting of periodic “cut-up” testing to ensure that the serial production forgings continued to conform to the specified requirements. If procedure X is invoked by the order, drawing or inspection/manufacturing schedule and/or
45、if procedures B, AX or CX are used for release tests (see section 6.4), forgings shall be selected from series production at the frequency stated therein. It is recommended that the maximum number of forgings manufactured between repeat “cut-up” testing conforming to procedure X shall be as stated i
46、n the following Table 1: Table 1 Mass of forging (kg) Number of forgings 1 2 000 1 25 As stated on the order, drawing, inspection schedule The testing requirements, including the location, type and size of test pieces shall be identical to those used for qualification of the pre-production. 6.6 Rete
47、sts Retests shall be required if the specified acceptance criteria are not fully met during qualification testing on pre-production forgings, process control testing (procedure X) or batch release testing. If the test product or test piece preparation is faulty, testing shall be re-applied at the or
48、iginal frequency after rectification of the original cause of failure. At least one of the retests shall be from forgings from which the unsatisfactory result was obtained (unless already rejected by the manufacturer after suitable identification of the cause of failure). It insufficient material re
49、mains, the purchaser shall advise as to how to proceed. prEN 4700-006:2009 (E) 8 If all retest results fulfil the specified acceptance criteria, the pre-production forging qualification/process control test (procedure X) shall be deemed satisfactory or the batch shall be accepted, a appropriate. If one or more retest results fail to fulfil the specified acceptance crit
