A product safety data sheet shall be available. 6 Technical requirements 6.1 Ge ne ra I The product shall be manufactured in accordance with the requirements of the relevant mate

18、rial standard and the applicable requirements of this specification. A manufacturing schedule shall be established and applied in accordance with EN 2078. Product shall satisfy the requirements of the material standard and/or order and shall be free from irregularities prejudiciable to the subsequen

19、t manufacture or use of this product. Not with standing 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 th

20、ose of the relevant material standard. 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 require

21、ments. If a specific line number is not 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 specif ication. 6.2 Qualification requirements Qualification requ

22、irements when invoked by the material 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 3 batches. 6.3 6.3.1 Release tests Release testing shall be the responsibility of the manufactu

23、rer. The purchaser 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 r

24、elease testing in order that these operations may be witnessed. Re lease req u i re men ts 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

25、corresponding acceptance criteria and/or values are stated in the applicable material standard, but see also section 6.2.4 “Capability clause“. 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 or

26、iginal cause of failure. Page 6 prEN 4800-5: 2001 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 alr

27、eady withdrawn by the manufacturer after suitable 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 - parti

28、ally or fully re-heat treated if heat treatment can rectify 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 An

29、y failure to meet the requirements of the material standard 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

30、 shall be mutually agreed by the manufacturer and purchaser. 6.3.5 Capability clause Where capability clause is invoked and where sufficient statistical evidence exists, the test shall not be carried out (unless specifically requested by the purchaser). However, this in no way reduces the obligation

31、s of the manufacturer to fulfil the requirements. If subsequent 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 t

32、he purchaser. 6.3.6 Statistical process control Reduction in the extent of release testing, other than that defined in 6.2.4 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

33、shall furnish, with each delivery, a report conforming 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; - qu

34、antity and dimensions; - manufacturing and inspection schedule reference; - cast and batch number; - batch and/or test samples heat treatment condition; - 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 bat
