34、tinuous 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 and toleranc
35、es 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 safety The
36、 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 requirements of the
37、 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 prejudicial to t
38、he subsequent manufacture or use of this product. 4) Published by: ASTM National (US) American Society for Testing and Materials http:/www.astm.org/ BS EN 4700-003:2010 EN 4700-003:2010 (E) 7 Notwithstanding previous acceptance complying with this material standard, any product that is found, at a l
39、ater 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 (inclusive) of the material standard and Table 2 relates to lines 30 onwards
40、 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 not shown in Tables 1 and 2, the requirement is stated in the material standard and/or order. 6.2 Qualification
41、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, coming from at least 2 casts. 6.3 Release requirement
42、s 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 by the order,
43、the manufacturer 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 p
44、articular 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 any requirement is not met, retests shall be carried out under the following conditions unless
45、otherwise stated in the material standard or order. If the test procedure or test piece preparation 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 tube with hardness results below
46、 the minimum or above the maximum value, the softest or hardest tube, as appropriate, shall be submitted to 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, furth
47、er 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 after suitable identification of the cause of failure. If all retest results are satisfactory, the b
48、atch 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 treatment can rectify the cause of the failure and tested as a completely new batch except for chemical
49、 composition and cleanness inspection. 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. BS EN 4700-003:2010 EN 4700-003:2010 (E) 8 For deformation under pressure, test samples from 25 % of the tubes in the batch shall be tested. All samples shall me
