29、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 be manufactured in accordance with the requirements of the relevant material standard and the applicable requ
30、irements of this specification. A manufacturing schedule shall be established and applied in accordance with EN 2078. The product shall satisfy the requirements of the material standard and/or order and shall be free from irregularities prejudicial to the subsequent manufacture or use of this produc
31、t. Notwithstanding previous acceptance complying with this material standard, any product that is found, at a later stage, to contain such defects shall be rejected. Unless otherwise specified, the requirements in Tables 1 and 2 shall apply in conjunction with those of the relevant material standard
32、. Table 1 relates 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. Lines 2 to 98 may also be opened in line 100 if the material standard details specific qualification requirements. If a specific line number is n
33、ot shown in Tables 1 and 2, the requirement is stated in the material standard and/or order. The requirements of the order and/or material standard shall over-ride the requirements of the technical specification. 6.2 Qualification requirements Qualification requirements when invoked by the material
34、standard and/or order are detailed in Tables 1 and 2. Unless otherwise agreed between the manufacturer and purchaser the qualification phase shall be run on the first three batches. 6.3 Release requirements 6.3.1 Release tests Release testing shall be the responsibility of the manufacturer. The purc
35、haser reserves the right to perform any of the inspections and/or tests required by the material standard and/or order. The test samples shall be representative of the product. When required the manufacturer shall inform the purchaser of the planned dates for extraction of samples and release testin
36、g in order that these operations may be witnessed. Tables 1 and 2 detail the requirements for each line of the material standard. Unless otherwise specifically requested by the purchaser, a particular inspection and/or test for release shall be carried out if corresponding acceptance criteria and/or
37、 values are stated in the applicable material standard, but see also in 6.3.5. BS EN 4800-007:2010EN 4800-007:2010 (E) 8 6.3.2 Retests If the test procedure or test piece preparation is faulty, testing shall be re-applied at the original frequency after rectification of the original cause of failure
38、. When failure cannot be attributed to faulty testing, or test piece preparation, further test samples shall be selected at twice the original frequency from the product, one of which shall be that on which the original results were obtained unless already withdrawn by the manufacturer after suitabl
39、e identification of the cause of failure. If all retest results are satisfactory, the batch shall be accepted. If one or more tests are unsatisfactory, the batch shall be: rejected; or 100 % retested and the conforming products accepted; or partially or fully re-heat treated if heat treatment can re
40、ctify the cause of the failure and tested as a completely new batch except for chemical composition, for which redetermination of hydrogen content is required. No product or test sample shall be re-heat treated more than twice. 6.3.3 Rejection Any failure to meet the requirements of the material sta
41、ndard shall be cause for rejection. 6.3.4 Special tests Special tests may be required by the purchaser. In such cases, the nature of the test, method, frequency and technical requirements shall be specified on the order or inspection schedule and shall be mutually agreed by the manufacturer and purc
42、haser. 6.3.5 Capability clause Where capability clause is invoked and where sufficient statistical evidence exists, the test need not be carried out (unless specifically requested by the purchaser). However, this in no way reduces the obligations of the manufacturer to fulfil the requirements. If su
43、bsequent testing indicates that the product does not comply with the requirements, the batch shall be rejected. If sufficient statistical evidence does not exist, the test shall be carried out at a frequency agreed between the manufacturer and the purchaser. 6.3.6 Statistical process control Reducti
44、on in the extent of release testing, other than that defined in 6.3.5 above, may be negotiated with the purchaser on the basis of appropriate statistical process control and/or statistical data. 6.3.7 Inspection and test report The manufacturer shall furnish, with each delivery, a report conforming
45、to the requirements of EN 2078 stating the following: manufacturers name and address and, if appropriate, identification of the plant; order number; material standard number; delivery condition and metallurgical code of the product; BS EN 4800-007:2010EN 4800-007:2010 (E) 9 quantity and dimensions;
46、manufacturing and inspection schedule reference; cast and batch number; batch and/or test samples heat treatment conditions; results of the tests and retests if any. 6.4 Traceability Each product shall be traceable to the cast, production batch and/or heat treatment batch at all stages of manufactur
47、e, testing and delivery.

48、 2 Chemical composition The test samples used for chemical analysis shall be representative of the product and shall be taken from each melt or cast. The method of chemical analysis shall be at the discretion of the manufacturer unless otherwise stated in the material standard or order. In cases of
49、dispute, the method of chemical analysis shall be agreed between the manufacturer and purchaser preferably using existing chemical analysis standards. The measured chemical composition shall be stated on the inspection certificate. 2 per cast 2 per cast Specific requirements for hydrogen content: The hydrogen content shall be determined on each batch in the delivery condition in accordance with EN 3976. 1 per cast 1 per cast 3 M
