34、atisfy the requirements of the order, drawing inspection schedule or material standard: 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 co

35、ntrol testing (Procedure X: see section 6.4) and (iii) batch release when cut-up testing 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, the requirements for each line of which ar

36、e detailed in Tables 2 and 3 of this technical specification. 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 not shown in a specific line in Tables 2 and 3, the

37、 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-production forgings. See Table 2, section 4.2. 6.3 Re-quali

38、fication 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 route; modifications to an existing die; use of a new (

39、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-qualification testing requirements, especially locati

40、on 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 responsibility of the manufacturer. The sampling procedure f

41、or 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: Copyright ASD-STAN Provided by IHS under license with AECMA Not for ResaleNo reproduction or networking permitted without license f

42、rom IHS-,-,-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 drawing, order or inspection schedule in which c

43、ase 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 forging stock. Procedure B shall only be us

44、ed 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 schedule shall specify how many test samples s

45、hall 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(s) selected from each production batch and

46、 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 control testing (Procedure X) Procedure X i

47、s 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 if procedures B, AX or CX are used for rel

48、ease 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 in 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
