25、r the purposes of this document, the terms and definitions given in EN 4259 apply. 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 referenc
26、e to an appropriate dimensional standard; product designation, 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 The products in the delivery condition shall fulfil t
27、he 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 r
28、equirements 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 prejudicial to the subsequent manufacture or use of this product
29、. 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 those of the relevant material standar
30、d. 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
31、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 specification. prEN 4800-002:2009 (E) 6 6.2 Qualification requirements Qualification requirements whe
32、n 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, coming from 3 different ingots. 6.3 Release requirements 6.3.1 Release tests Release testing sha
33、ll 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 be representative of the product. When required the manufacturer shall inform the purchaser of the plan
34、ned 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 otherwise specifically requested by the purchaser, a particular inspection and/or test for release shall be c
35、arried out if corresponding acceptance criteria and/or values are stated in the applicable material standard, but see also in 6.3.5. 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 caus
36、e 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 the product, one of which shall be that on which the original results were obtained unless already withdrawn by the manufacturer a
37、fter 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 partially or fully re-heat treated if heat trea
38、tment 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 Any failure to meet the requirements of the m
39、aterial 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 shall be mutually agreed by the manufactur
40、er 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 obligations of the manufacturer to fulfil the require
41、ments. If subsequent testing indicates that the product does not comply with the requirements, the batch shall be rejected. prEN 4800-002:2009 (E) 7 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.
42、6 Statistical process control Reduction 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, wit
43、h 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; quantity and dimensions; manuf
44、acturing 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 batch at all stages of manufacture, tes
45、ting and delivery. prEN 4800-002:2009 (E) 8 Table 1 Technical requirements for lines 1 to 29, where appropriate Frequency of testing Material standard line reference No Title Requirements Qualification Release 1 Material designation See EN 2032-1. The test samples used for chemical analysis shall be
46、 representative of the product and shall be taken from location corresponding to top and bottom of each ingot produced after the final melting stage. 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
47、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 2 Chemical composition Specific requirements f
48、or hydrogen content: The hydrogen content shall be determined on each batch in the delivery condition in accordance with EN 3976. 1 per batch 1 per batch 3 Method of melting Method of melting consists of multiple melt using combination of non-consumable electrode, consumable electrode and cold heart
49、h (electron beam or plasma arc) melting practices. Some of the following requirements are dependent on the actual melting route non-consumable electrode melting should be used for consolidation purpose only. 1 Raw material: Raw materials shall be purchased only from suppliers approved by the manufacturer and registered in his list of approved suppliers. Approval of suppliers shall be made
