26、:2009 (E) 5 4 Wording of order The order shall clearly indicate: quantities to be supplied; dates of delivery; material standard number; part number delivery condition and metallurgical code of products; dimensions and tolerances or reference to an appropriate dimensional standard; product designati
27、on, when required; forwarding address; nature and type of packing, if required; definition and frequency of any special tests and their retest procedures, if required. 5 Health and safety Products in the delivery condition shall fulfil the health and safety laws of the area of the country when and w
28、here 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 standard: see Table 1, line 5. The order, drawing or inspection schedule shall specify the
29、 tests to be performed upon (i) pre-forgings for qualification and/or requalification (ii) serial production forgings for process control testing (Procedure X: see 6.5) and (iii) batch release when cut-up testing or forgings is required. Unless otherwise specified on the order, drawing or inspection
30、 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 material standard and Table 3 relates to lines 30 onwards in w
31、hich the sub-line 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 requirements See line 100 in Table 3 of this technical speci
32、fication. Qualification shall normally comprise assessment of pre-production forgings. See Table 2, No 4.2.

33、uirements Re-qualification of serial production 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 d
34、ie; use of a new (replacement) die; 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-
35、qualification 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 requipements Release testing shall be the respons
36、ibility 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. Procedure A: Separate forged test samples shall be produced from the same batc
37、h 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). Procedure B: Separate forged heat treatment control t
38、est samples shall be prepared which conform to the same 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 co
39、njunction 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 on the drawing, order or inspection s
40、chedule 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. The purchaser reserves the right to perfo
41、rm any of the inspections and/or 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. Copyright AS

43、rial production forgings continues 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 release tests (see 6.4), forgings shall be selected from series production at the frequency
44、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 Th
45、e 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 Retests Retests shall be required if the specified acceptance criteria are not fully met during qualification testing of pre-production forgings,
46、 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 original cause of failure. At least one of the retests shall be from forgings from which the unsa
47、tisfactory 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 proceed. If all retest results fulfil the specified acceptance criteria, the pre-production fo
48、rging qualification/process control test (procedure X) shall be deemed satisfactory or the batch shall be accepted, as appropriate. If one or more retest results fail to fulfil the specified acceptance criteria, the following actions shall be taken: a) For qualification testing of pre-production forgings, advice shall be sought from the purchaser as to whether the retest results are acceptable for that part of the forging. If so, this shall be denoted by a note on the drawing, together with values which are acceptabl
