25、ion, see EN 4259. 4 Wording of order The order shall clearly indicate: quantities to be supplied; dates of delivery; material standard number; delivery condition and metallurgical code of products; dimensions and tolerances or reference to an appropriate dimensional standard; product designation, wh
26、en 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 and where i
27、t is to be delivered. A product safety data sheet shall be available. 6 Tech n i cal req u i remen ts 6.1 General 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 sh
28、all be established and applied in accordance with EN 2078. Product shall satisfy the requirements of the material standard andlor order and shall be free from irregularities prejudicial to the subsequent manufacture or use of this product. Not with standing previous acceptance complying with this ma
29、terial 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. Table 1 relates to lines 1 to 29 (inclusive) of the materia
30、l 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 not shown in tables 1 and 2, the requirement is stated in the
31、material standard and/or order. The requirements of the order andlor material standard shall over-ride the requirements of the technical specification. 6.2 Qualification requirements Qualification requirements when invoked by the material standard and/or order are detailed in tables 1 and 2. Unless
32、otherwise agreed between the manufacturer and purchaser the qualification phase shall be run on the first 3 batches coming from 3 ingots. Page 6 prEN 4800-1 : 2002 6.3 Release requirements 6.3.1 Release tests Release testing shall be the responsibility of the manufacturer. The purchaser reserves the
33、 right to perform any of the inspections andlor tests required by the material standard andlor 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 testing in order that th
34、ese 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 andlor values are stated
35、 in the applicable material standard, but see also section 6.3.5 “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 original cause of failure. When failure cannot be attributed
36、 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 suitable identification of the cause of fa
37、ilure. If all retest results are satisfactory, the batch shall be accepted. If one or more tests are unsatisfactory, the batch 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 failu
38、re 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 standard shall be cause for rej
39、ection. 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 purchaser. 6.3.5 Capability clau
40、se Where this is invoked and where sufficient evidence exists, the test shall 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 subsequent testing indicates that the product does not
41、 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 Reduction in the extent of release testing, other than that
42、 defined in 6.3.5 above, may be negotiated with the purchaser on the basis of appropriate statistical process control andlor statistical data. Page 7 prEN 4800-1 : 2002 6.3.7 Inspection and test report The manufacturer shall furnish, with each delivery, a report conforming to the requirements of EN
43、2078 stating the following: manufacturers name and address and, if appropriate, identification of the plant; order number; material standard number; method of melting; delivery condition and metallurgical code of the product; quantity and dimensions; manufacturing and inspection schedule reference;
44、cast and batch number; batch and/or test samples heat treatment condition; results of the tests and retests if any. Traceability Each product shall be traceable to the cast, production batch and/or heat treatment batch at ali stages of manufacture, testing and delivery. Page 8 prEN 4800-1: 2002 I CI
