A blank electronic version of this table is available from the Committee Secretary or it can be downloaded from the BSI web site at: http:iiwww. bsi-global .corn/Stai76ar+ - dates of delivery; -

15、 material standard number; - delivery condition and metallurgical code of products; - dimensions and tolerances or reference to an appropriate dimensional standard; - product designation, when required; - forwarding address; - nature and type of packing, if required; - definition and frequency of an

16、y 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 and where it is to be delivered. A product safety data sheet shall be available. 6 Technical requirements 6.1 Genera

17、l The product shall be manufactured in accordance with the requirements of the relevant material 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 materia

18、l standard and/or order and shall be free from irregularities prejudiciable to the subsequent 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. Unles

19、s otherwise specified, the requirements in tables 1 and 2 shall apply in conjunction with those 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 ma

20、y also be opened in line 100 if the material standard details specific qualification requirements. 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 req

21、uirements of the technical specification. 6.2 Qual fi cation req u i remen ts Qualification requirements 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

22、 3 batches. Page 6 prEN 4800-4: 2001 6.3 Release req u irements 6.3.1 Release tests Release testing shall be the responsibility of the manufacturer. 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

23、be representative of the product. 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. Tables 1 and 2 detail the requirements for each line of the material standard. Unless otherw

24、ise specifically requested by the purchaser, a particular inspection and/or test for release shall be carried out if 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

25、test piece preparation is faulty, testing shall be re-applied at the original frequency after rectification of the original cause of failure. When failure cannot be attributed to faulty testing, or test piece preparation, further test samples shall be selected at twice the original frequency from th

26、e product, one of which shall be that on which the original results were obtained unless already 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 batc

27、h shall be: - rejected, or - 1 O0 % retested and the conforming products accepted, or - partially 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 req

28、uired . 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 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, f

29、requency and technical requirements shall be specified on the order or inspection schedule and 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 (u

30、nless specifically requested by the purchaser). However, this in no way reduces the obligations 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

31、 not exist, the test shall be carried out at a frequency agreed between the manufacturer and the 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 statistic

32、al process control and/or statistical data. Page 7 prEN 4800-4: 2001 6.3.7 Inspection and test report The manufacturer 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

33、the plant; - order number; - material standard number; - delivery condition and metallurgical code of the product; - quantity and dimensions; - manufacturing and inspection schedule reference; - cast and batch number; - batch and/or test samples heat treatment condition; - results of the tests and r

34、etests if any. 6.4 Traceability Each product shall be traceable to the cast, production batch and/or heat treatment batch at all stages of manufacture, testing and delivery.
