22、 furnaces mixed in the same furnace or ladle before pouring 3.2 cast solid metal resulting from the pouring of a single melt 3.3 parent cast a cast of remelting stock to be used for the production of casting 3.4 approved scrap scrap used for the production of remelting stock. It arise from the manuf
23、acturers own production or from that of the purchaser. Scrap used for the production of castings shall be restricted to runners and risers, rejected castings and heavy fettling scrap but shall exclude machining chips, turnings or small particles, except those from the manufacturers own production NO
24、TE Scrap shall be subject of preparation and evaluation by approved procedures and facilities which shall include verification of chemical composition, freedom from contamination and the absence of foreign material. 2) Published by: American Society for Testing and Materials (ASTM), 100 Barr Harbor

26、 a batch of remelting stock consist of material of the same nominal dimensions and from the same melt 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 tol
27、erances 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 safet
28、y 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 in accordance with the requirements of
29、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 prejudicial t
30、o the subsequent manufacture or use of this product. prEN 4700-007:2009 (E) 6 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 an
31、d 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 subline format is also used. Lines 2 to 98 may also be opened in line 100 if the material standard d
32、etails 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 order and/or material standard shall over-ride the requirements of the technical specification. 6.2 Qualifica
33、tion 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 requir
34、ements 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 on the or
35、der, 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
36、, 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 6.3.5. 6.3.2 Retests If any requirement is not met, retests shall be carried out under the following conditions unles
37、s 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. When failure cannot be attributed
38、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 were obtained unless already withdrawn by the manufacturer after suitable identification of the cause of fai
39、lure. 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 accepted, or partially or fully re-heat treated if heat treatment can rectify the cause of the failure and t
40、ested as a completely new batch except for chemical 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. prEN 4700-007:2009 (E) 7 6.3.3
41、 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 such cases, the nature of the test, method, frequency and technical requirements shall be specified on the order or inspection
42、 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 purchaser). However, this in no way reduce
43、s the obligations of the manufacturer to fulfil the requirements. If subsequent testing indicates that the product 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,
44、 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 furnish, with each delivery, a report conforming to the requirements of EN 2078 stating the following: manufacturers name and
45、 address and, if appropriate, identification of the plant; order number; material standard number; delivery condition 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 condi
46、tions; 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 manufacture, testing and delivery. prEN 4700-007:2009 (E) 8 Table 1 Technical requirements for lines 1 to 29, where appropriate
47、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 composition The chemical composition of the alloy shall comply with requirements of the material standard. The samples taken for
48、 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 the relevant EN or ISO standard shall be used. If no EN or ISO standard exists, a fundamental and agreed method of chemical analy
49、sis calibrated against accepted reference standards shall be used. In the case of remelted material (VAR or ESR), 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 purcha
