24、03:2009 (E) 5 dimensions and tolerances or reference to an appropriate dimensional standard; product designation, when required; forwarding address; nature and type of packing, if required. 5 Health and safety The products in the delivery condition shall fulfil the health and safety laws of the area

25、 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 relevant material standard and the applicable requirements of this specification. A

26、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 the subsequent manufacture or use of this product. Not with standing previous acceptan

27、ce 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 apply in conjunction with those of the relevant material standard. Table 1 relates to lines 1 to 29 (

28、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 specific qualification requirements. If a specific line number is not shown in Tables 1 and 2, the requ

29、irement 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 Qualification requirements Qualification requirements when invoked by the material standard and/or order are detailed i

30、n 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 3 different ingots. 6.3 Release requirements 6.3.1 Release tests Release testing shall be the responsibility of the manufacturer. The purchaser re

31、serves the right to perform any of the inspections and/or tests required by the material standard and/or order. Copyright ASD-STAN Provided by IHS under license with AECMA Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-prEN 4800-003:2009 (E) 6 The test samples sha

32、ll be representative of the product. When required 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 oth

33、erwise 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. 6.3.2 Retests If the test procedure or test piece preparation

34、 is faulty, testing shall be re-applied at the original frequency after rectification of the original cause of failure. 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 whic

35、h 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 batch shall be accepted. If one or more tests are unsatisfactory, the batch shall be: rejected,

36、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 composition, for which redetermination of hydrogen content is required. No product or test sam

37、ple shall be re-heat treated more than twice 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 such cases, the nature of the test, method, frequency and technical requirem

38、ents 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 capability clause is invoked and where sufficient statistical evidence exists, the test shall not be carried out (unless specifically requested by

39、 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 requirements, the batch shall be rejected. If sufficient statistical evidence does not exist, the test shall be c

40、arried out at a frequency agreed between the manufacturer and the 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 negotiated with the purchaser on the basis of appropriate statistical process control and/or stati

42、ments of EN 2078 stating the following: manufacturers name and 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 an

43、d batch number; batch and/or test samples heat treatment condition; 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.

45、e 1 Material designation See EN 2032-1. The test samples used for chemical analysis shall be representative of the product and shall be taken from location corresponding to top and bottom of each ingot produced after the final melting stage. The method of chemical analysis shall be at the discretion

46、 of the manufacturer unless otherwise stated in the material standard or order. In cases of dispute, the method of chemical analysis shall be agreed between the manufacturer and purchaser preferably using existing chemical analysis standards. The measured chemical composition shall be stated on the

48、iple melt using combination of non-consumable electrode, consumable electrode and cold hearth (electron beam or plasma arc) melting practices. Some of the following requirements are dependent on the actual melting route non-consumable electrode melting should be used for consolidation purpose only. 1 Raw material: Raw materials shall be purchased only from suppliers approved by the manufacturer and registered in his list of approved suppliers.
