25、equal to 8 hours may be considered as the same heat treatment charge. Continuous heat treatment can be an option. 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; dimens

26、ions 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 procedures, if required. 5 Heal

27、th and safety The products in the delivery condition shall fulfil the current health and safety laws of the area of the country 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 r

28、equirements 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 from irregularitie

29、s prejudicial to the subsequent manufacture or use of this product. Notwithstanding 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

30、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 may also be opened in line 100 if the material standard details sp

31、ecific 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. prEN 4700-004:2009 (E) 6 6.2 Qualification requirements Qualification requirements when invoked by the material standard and/or order are deta

32、iled 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 at least 2 casts. 6.3 Release requirements 6.3.1 Release tests Release testing shall be the responsibility of the manufacturer. The purchase

33、r 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 by the order, the manufacturer shall inform the purchaser of the planned dates for extraction of samples and rele

34、ase 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 carried out if corresponding acceptance crite

35、ria and/or values 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

36、 is faulty, testing 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. For wire with hardness results below the minimum or above the maximum value, the softest or hardest wire, as appropriate, shall be subm

37、itted to a tensile test. If the results comply with the specified tensile requirements, all wire shall be accepted. 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 sh

38、all 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 batch shall be: rejected, or 1

39、00 % 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 and cleanness inspection. The reheat treatment shall be stated on the release test cer

40、tificate. 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. prEN 4700-004:2009 (E) 7 6.3.4 Special tests Special tests may be requir

41、ed 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 capability clause is invoked and where suf

42、ficient 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 does not comply with the requiremen

43、ts, 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 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

44、 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, with each delivery, a report conforming to the requirements of EN 2078 stating the following: manufacturers name and addres

45、s 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; cast and batch number; all heat treatment, including re-h

46、eat treatment and, where appropriate, straightening and stress relieving parameters, applied to the batch; test sample heat treatment; 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

47、manufacture, testing and delivery. prEN 4700-004:2009 (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 EN 2032-1 and EN 10027-1 if applicable 2 Chemical

48、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, but in cases of dispute, the reference method set out in t

49、he 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, samples shall be taken from positions as follows: a) Vacuum arc remelted (VAR) ingots: the bottom of each ingot or ingot product. b) Electroflux or electr
