24、9428-2959 USA. prEN 4800-006:2009 (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
25、 standard; product designation, 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 ar
26、ea 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 schedule or material standard: see Table 1, line 5. The order, drawing or inspectio
27、n 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 6.5) and (iii) batch release when cut-up testing or forgings is required. Unless otherwise specified on the
28、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 material standard and Table 3 rela
29、tes 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 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 Tab
30、le 3 of this technical specification. Qualification shall normally comprise assessment of pre-production forgings. See Table 2, No 4.2. prEN 4800-006:2009 (E) 6 6.3 Re-qualification requirements Re-qualification of serial production forgings may be required, at the purchasers discretion, in the foll
31、owing 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; modifications to the forging manufacturing route; use of a new forging manufact
32、urer; 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 location of test pieces, shall be identical to those used for the in
33、itial 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 responsibility of the manufacturer. The sampling procedure for release testing shall be one of the following, as specified
34、 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 forgings. Procedure A may be used alone unless denote
35、d 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 test samples shall be prepared which conform to the same material standard as the production forgings, but may origi
36、nate 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 6.5). Procedure C: Integral test samples shall be removed from each forgings. The o
37、rder, 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 only in conjunction with procedure X (See 6.5). Procedure D: Test samples
38、 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 tests required by the material standard, drawing, order or inspection schedule. Wh
39、en 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. prEN 4800-006:2009 (E) 7 6.5 Process control testing (Procedure X) Procedure X is process control procedure consisting of perio
40、dic “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/manufacturing schedule and/or if procedures B, AX or CX are used for release tests (see 6.4), forgings shall be selecte
41、d 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
42、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 Retests Retests shall be required if the specified acceptance criteria are not fully met during qualifi
43、cation 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 original cause of failure. At least one of the retests
44、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 proceed. If all retest results fulfil the specified
45、acceptance criteria, the pre-production forging 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 q
46、ualification 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 acceptable for that location. Alternatively,
47、if it is essential that the specified acceptance criteria are achieved at all locations, the purchaser may request modifications to be made to the manufacturer route. b) For process control testing (procedure X), the tests shall be repeated on a second forging taken as close as possible to the above
48、 in the production sequence and/or and extensive review shall be made of the manufacturing records of forgings made since the previous control tests. Serial production of the forging in question (and others if appropriate/deemed necessary) shall not continue until the cause of the unsatisfactory val
49、ues has been ascertained and rectified. c) For batch release testing, the batch shall be either: rejected, or partially of fully re-heat treated if it is believed that re-heat treatment can rectify the cause of the failure and then test as a completely new batch from which the conforming products shall be accepted. The re-heat treatment shall be stated on the test and inspection report. No
