25、nitions For the purposes of this document, the terms and definitions given in EN 4259 apply. For definitions specific to steel, see EN 10079. 4 Wording of order The order shall clearly indicate: quantities to be supplied; dates of delivery; material standard number; delivery condition and metallurgi
26、cal 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; surface protection, if appropriate; definition and frequency of any special tests and their retest pro
27、cedures, 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
28、 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. 2) Published by: American Society for Testing and Materials (ASTM), 100 Barr Harbor Driv
29、e, PO Box C700, West Conshohocken, PA, 19428-2959 USA. prEN 4700-005:2009 (E) 6 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. Notwithstanding previous acceptance com
30、plying 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 standard. Table 1 relates to lines 1 to 29 (inclus
31、ive) 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 standard details specific qualification requirements. If a specific line number is not shown in Tables 1 and 2, the requirement
32、 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. 6.2 Qualification requirements Qualification requirements when invoked by the material standard and/or order are detailed in Table
33、s 1 and 2. Unless otherwise agreed between the manufacturer and purchaser the qualification phase shall be run on the first 3 batches, coming from at least 2 casts. 6.3 Release requirements 6.3.1 Release tests Release testing shall be the responsibility of the manufacturer. The purchaser reserves th
34、e 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 on the order, the manufacturer shall inform the purchaser of the planned dates for extraction of samples and release testing i
35、n 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 carried out if corresponding acceptance criteria and/or va
36、lues are stated in the applicable material standard, but see also in 6.3.5. 6.3.2 Retests If any requirement is not met, retests shall be carried out under the following conditions unless otherwise stated in the material standard or order. If the test procedure or test piece preparation is faulty, t
37、esting shall be re-applied at the original frequency after rectification of the original cause of failure, on a test sample located near the first one. When failure cannot be attributed to faulty testing, or test piece preparation, further test samples shall be selected at twice the original frequen
38、cy 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 failure. If all retest results are satisfactory, the batch shall be accepted. If one or more tests are unsatisfactory
39、, the batch shall be: rejected, or 100 % retested and the conforming products accepted, or prEN 4700-005:2009 (E) 7 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 and cleanness inspection.
40、 The reheat treatment shall be stated on the release test certificate. For cleanness inspection, if the material fails the requirement the product may be cut back before retesting. 6.3.3 Rejection Any failure to meet the requirements of the material standard shall be cause for rejection. 6.3.4 Speci
41、al 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 clause Where the capabi
42、lity clause is invoked and where sufficient statistical evidence exists, the test need 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
43、 does not comply with the requirements, the batch shall be rejected. 6.3.6 Statistical process control Reduction in the extent of release testing, other than that defined in 6.3.4 above, may be negotiated with the purchaser on the basis of appropriate statistical process control and/or statistical d
44、ata. 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; delivery condit
45、ion 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 cast, prod
46、uction batch and/or heat treatment batch at all stages of manufacture, testing and delivery. prEN 4700-005:2009 (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 Material desi
47、gnation EN 2032-1 and EN 10027-1 if applicable 2 Chemical composition The chemical composition of the alloy shall comply with requirements of the material standard. The samples taken for analysis shall be representative of the melt. The method of analysis shall be at the option of the manufacturer,
48、but in cases of dispute, the reference method set out in the relevant EN or ISO standard shall be used. If no EN or ISO standard exists, a fundamental and agreed method of chemical analysis calibrated against accepted reference standards shall be used. In the case of remelted material (VAR or ESR),
49、samples shall be taken from the bottom or the top of one ingot or ingot product. An analysis shall be made of each sample and certificates of analysis shall be supplied to the purchaser. The elements to be determined shall be as required by the material standard or as agreed between the manufacturer and the purchaser. Elements not quoted in the material standard shall not be inte
