32、006:2010 (E) 7 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 desig
33、nation, 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 a
34、nd 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 inspection schedule shall specify
35、 the tests to be performed upon: a) pre-forgings for qualification and/or requalification; b) serial production forgings for process control testing (Procedure X: see 6.5); and c) batch release when cut-up testing or forgings is required. Unless otherwise specified on the order, drawing or inspectio
36、n 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
37、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. BS EN 4800-006:2010EN 4800-006:2010 (E) 8 6.2 Qualification requirements See
38、line 100 in Table 3 of this technical specification. Qualification shall normally comprise assessment of pre-production forgings. See Table 2, No. 4.2. 6.3 Re-qualification requirements Re-qualification of serial production forgings may be required, at the purchasers discretion, in the following cas
39、es: 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 manufacturer; whe
40、n 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 initial qua
41、lification 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 for release testing shall be one of the following, as specified on the o
42、rder, 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 denoted AX on t
43、he 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 originate from
44、 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 order, dra
45、wing 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 shall be
46、 machined from forging(s) selected from each production batch and at locations specified on the order, drawing or inspection schedule. BS EN 4800-006:2010EN 4800-006:2010 (E) 9 The purchaser reserves the right to perform any of the inspections and/or tests required by the material standard, drawing,
47、 order or inspection schedule. When required, the manufacturer 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 is a process control procedure consistin
48、g 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 (see 6.4), forgings shall
49、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 te
