23、ety 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 o

24、f 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

25、 to the subsequent manufacture or use of this product. Not with standing 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 and 2 shall apply in co

26、njunction 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 standard details specific qual

27、ification 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 Qualification requirements Qu

28、alification 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. 6.3 Release requirements 6.3.1 Release tests Release testing shall b

29、e 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 the manufacturer shall inform the purchaser of the planned

30、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 particular inspection and/or test for release shall be carri

31、ed out if corresponding acceptance criteria and/or values are stated in the applicable material standard, but see also in 6.3.5.

32、.2 Retests 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. When failure cannot be attributed to faulty testing, or test piece preparation, further test samples shall be selected at

33、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 batch shall be accepted. If one or mor

34、e 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 composition, for which redeterminati

35、on of hydrogen content is required. No product or test sample 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 n

36、ature 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 capability clause is invoked and where sufficient statistical evidence exists, the test

37、 need not be carried out (unless specifically requested by 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 sufficien

38、t statistical evidence does not exist, the test shall be carried 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 bas

39、is 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 address and, if appropriate, identification of

40、the plant; order number; material standard number; delivery condition and metallurgical code of the product; quantity and dimensions; Copyright ASD-STAN Provided by IHS under license with AECMA Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-prEN 4800-007:2009 (E)

41、7 manufacturing and inspection schedule reference; cast and batch number; batch and/or test samples heat treatment conditions; 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 manufact

42、ure, testing and delivery.

43、d line reference No Title Requirements Qualification Release 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 each melt or cast. The method of chemical analysis shall be at the discretion of the manufactu

44、rer 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 inspection certif

46、on Beam or Plasma Arc) and/or Consumable Electrode Vacuum Arc Melting. An initial non-consumable electrode melt is allowed provided a water-cooled copper electrode is used. Some of the following requirements depend on whether the melting method includes Cold Hearth. 1 Raw material: Raw materials sha

47、ll be purchased only from suppliers approved by the manufacturer and registered in his list of approved suppliers. Approval of suppliers shall be made in accordance with written procedures contained within the quality assurance system of the manufacturer. Titanium sponge and alloying elements: The r

48、equirements shall be specified by the manufacturer who shall also establish the following procedures for the evaluation and acceptance testing of each batch. titanium sponge: manufacturing method, level of impurities, particle size, freedom from surface contamination ; alloying elements: chemical composition including level of impurities, particle size, freedom from foreign particles. continued Copyright ASD-STAN Provided by IHS under license with AECMA Not for ResaleNo reproduction or networking permitted without license from IHS-,-,
