For definitions specific to steel, see EN 10079. 3.1 batch for heat treatment using a continuous furn
24、ace, a continuous run of less than or equal to 8 hours may be considered as the same heat treatment charge 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 an
25、d 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 Health and
26、safety The product 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 requireme
27、nts 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 irregularities prejud
28、icial 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. prEN 4700-003:2009 (E) 6 Unless otherwise specified, the requirements in Tabl
29、es 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 sub-line 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. 6.2 Qualification requirements Qualification requirements when invoked by the material standard and/or order are detailed in
31、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 purchaser reserv
32、es 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 release test
33、ing 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 criteria and/
34、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 is faul
35、ty, 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 tube with hardness results below the minimum or above the maximum value, the softest or hardest tube, as appropriate, shall be submitted to
36、 a tensile test. If the results comply with the specified tensile requirements, all tube 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 shall be t
37、hat 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 100 % ret
38、ested 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 certificate
39、. For cleanness inspection, if the material fails the requirement the product may be cut back before retesting. For deformation under pressure, test samples from 25 % of the tubes in the batch shall be tested. All samples shall meet the requirements. prEN 4700-003:2009 (E) 7 6.3.3 Rejection Any fail
40、ure 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 on the order or inspection schedule and shall
41、 be mutually agreed by the manufacturer and purchaser. 6.3.5 Capability clause Where the capability 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 o
42、f 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 carried out at a frequency agreed between the manufacturer and purc
43、haser. 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 statistical data. 6.3.7 Inspection and test report The manufacturer shall f
44、urnish, 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; method of melting; delivery condition and metallurgical code of the product;
45、quantity and dimensions; manufacturing and inspection schedule reference; cast and batch number; all heat treatment, including re-heat treatment and, where appropriate, straightening and stress relieving parameters, applied to the batch; test samples heat treatment; results of the tests and retests
46、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, testing and delivery. prEN 4700-003:2009 (E) 8 Table 1 Technical requirements for lines 1 to 29, where appropriate Frequency of testing Material standard l
47、ine reference No. Title Requirements Qualification Release 1 Material designation 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
48、 melt. The method of analysis shall be at the option of the manufacturer, 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 referenc
49、e 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 electroslag remelted (ESR) ingots: the top and bottom ends of each ingot or ingot product. An analysis shall be made of each sample and certificates of analysis shall be supplied to the purchaser
