33、s 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 metallurgical code of products; dimensions and tolerances or
34、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 Products
35、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 accordance with the requirements of the relevan
36、t material standard and the applicable requirements of this specification. A manufacturing schedule shall be established and applied in accordance with EN 2078. 3) Published by: ASTM National (US) American Society for Testing and Materials http:/www.astm.org/ BS EN 4700-005:2010EN 4700-005:2010 (E)
37、7 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 complying with this material standard, any product that is found, at a later stag
38、e, 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 in which
39、 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 is stated in the material standard and/or order. The requirements of the orde
40、r 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 Tables 1 and 2. Unless otherwise agreed between the manufacturer and purchaser the
41、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 the right to perform any of the inspections and/or tests required by the materia
42、l 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 in order that these operations may be witnessed. Tables 1 and 2 detail the requ
43、irements 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 values are stated in the applicable material standard, but see also in 6.3.5. 6.
44、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, testing shall be re-applied at the original frequency after rectification of th
45、e 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 frequency from the product, one of which shall be that on which the original results
46、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 % retested and the conforming products
47、accepted, or BS EN 4700-005:2010EN 4700-005:2010 (E) 8 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
48、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. 6.3.4 Special tests Special tests may be required by the purchaser. In s
49、uch 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 sufficient statistical evidence exists, the test need not be carried out (unless specifically requested by the purc
