28、roducts in the delivery 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
29、schedule or material standard: see table 1, line 5. The order, drawing or inspection schedule shall specify the tests to be performed upon (i) pre-forgings for qualification and/or requalification (i) serial production forgings for process control testing (Procedure X: see section 6.5) and (iii) bat
30、ch 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 are detailed in tables 1 and 2 of this technical specificati
31、on. Table 1 related to lines 1 to 29 (inclusive) of the material standard and table 2 relates to lines 30 onwards in which the sub-line format is also used. If a particular test is needed but not shown in a specific line in tables 1 and 2, the requirement shall be specified on the order, drawing, in
32、spection schedule or material standard. 6.2 Qualification requirements See line 1 O0 in table 2 of this technical specification. Qualification shall normally comprise assessment of pre-production forgings. See table 1, section 4.2. 6.3 Re-qualification requirements Re-qualification of serial product
33、ion forgings may be required, at the purchasers discretion, 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 (replacement) die
34、; - modifications to the forging manufacturing route; - use of a new forging manufacturer; - 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 requ
35、irements, 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.

The sampling procedure for release
37、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. - Procedure A: Separate forged test samples shall be produced from the same batch of forging stock as that used to make the serial production
38、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 section 6.5). - Procedure B: Separate forged heat treatment control test samples shall be prepared which conform to the s
39、ame material standard as the production forgings, but may originate from a different batch of forging 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 section 6.5). - Proc
40、edure 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 on the drawing, order or inspection schedule in which case it shall be applied
41、only in conjunction with procedure X (See section 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. The purchaser reserves the right to perform any of the inspections and/or
42、 tests required by the material standard, drawing, order 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.

43、 As stated on the order, drawing, inspection schedule 6.5 Procedure X is process control procedure consisting of periodic “cut-up” testing to ensure that the serial production forgings continues to conform to the specified requirements. If procedure X is invoked by the order, drawing or inspection/m
44、anufacturing schedule and/or 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 pro
45、cedure X shall be as stated in the following table: Process control testing (Procedure X) 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 Re tests Retests shall be required if the specified a
46、cceptance criteria are not fully met during qualification testing of 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 original frequency after rectification of the orig
47、inal 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 remains, the purchaser shall advise as to how to p
48、roceed. 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, as appropriate.
