A product safety data sheet shall be available. 6

    26、 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 tests to be performed upon (i) pre-forgings for qualification and/or requali

    27、fication (i) serial production forgings for process control testing (Procedure X: see section 6.5) 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 materia

    28、l standard, the requirements for each line of which are detailed in tables 1 and 2 of this technical specification. 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

    29、but not shown in a specific line in tables 1 and 2, the requirement shall be specified on the order, drawing, inspection 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-pro

    30、duction forgings. See table 1, section 4.2. 6.3 Re-qualification requirements 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 fo

    31、rging 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 manufacturer; - when a significant time interval (usually several years) had elapsed between forging campaigns

    32、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 unless otherwise specified on the order, drawing

    33、 or inspection schedule. Page 6 prEN 4800-6: 2002 Mass of forging (kg) II I mass I 2 2 25 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 inspecti

    34、on 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 denoted AX on the drawing, order or in

    35、spection 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 same material standard as the production forgings, but may originate from a different

    36、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). - Procedure C: Integral test samples shall be removed from each forgings. The order, drawin

    37、g 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 section 6.5). - Procedure D: Test samples s

    38、hall 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. When

    39、 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. Number of forgings 5 2 O00 I1 O00 I400 I 200 As stated on the order, drawing, inspection schedule 6.5 Procedure X is process cont

    40、rol 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/manufacturing schedule and/or if procedures B, AX or CX are used for release tests (se

    41、e 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: Process control testing (Procedur

    42、e 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 acceptance criteria are not fully met during qualification testing of pre-production f

    43、orgings, 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

    44、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 acceptance criteria, the pre-produ

    45、ction forging qualification/process control test (procedure X) shall be deemed satisfactory or the batch shall be accepted, as appropriate. Page 7 prEN 4800-6: 2002 If one or more retest results fail to fulfil the specified acceptance criteria, the following actions shall be taken: a) For qualificat

    46、ion 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, if it is

    47、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 in the p

    48、roduction 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 values has b

    49、een 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 products or test sample shall be re-heat treated more than once. 6.7 Special tests Special tests and/or inspections may be required by the purchaser. In such cases, the nature of th
