25、ry 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 any special tests and their retest procedures,
26、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 General The product shall be manufactured in accor
27、dance 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 material standard and/or order and shall be free fr
28、om irregularities prejudicial 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. Unless otherwise specified, the requirements in Tab
29、les 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 subline format is also used. Lines 2 to 98 may also be opened in line 100 if the material st
30、andard 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 requirements of the technical specification. prEN
31、4800-005:2009 (E) 6 6.2 Qualification requirements 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 3 batches. 6.3 Release req
32、uirements 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 be representative of the product. When required the ma
33、nufacturer 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 otherwise specifically requested by the purchaser, a particu
34、lar 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 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 f
35、requency 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 the product, one of which shall be that on which the original results were obtain
36、ed 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 batch shall be: rejected, or 100 % retested and the conforming products accepted, o
37、r 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 required. No product or test sample shall be re-heat treated more than twice, or cut back
38、 and 100 % retested. 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, frequency and technical requirements shall be specified
39、on the order or inspection schedule and shall be mutually agreed by the manufacturer and purchaser. prEN 4800-005:2009 (E) 7 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
40、 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 not exist, the test shall be c
41、arried 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 6.3.5 above, may be negotiated with the purchaser on the basis of appropriate statistical process control and/or stati
42、stical data. 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 the plant; order number; material standard number; deliver
43、y 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 conditions; results of the tests and retests if any. 6.4 Traceability Each product shall be traceable to the ca
44、st, production batch and/or heat treatment batch at all stages of manufacture, testing and delivery. prEN 4800-005:2009 (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 Materi
45、al designation See EN 2032-1. The test samples used for chemical analysis shall be 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 ma
46、nufacturer unless otherwise stated in the material standard or order. In cases of 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
47、 certificate. 2 per cast 2 per cast 2 Chemical composition 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 batch 1 per batch 3 Method of melting Method of melting shall consist of Cold Hear
48、th (Electron Beam or Plasma Arc) and/or Consumable Electrode Vacuum Arc Melting. An initial non-consumable electrode melt is allowed provided a water cooled electrode is used. Some of the following requirements depend on whether the melting method includes Cold Hearth. 1 Raw material: Raw materials
