26、he requirements of the relevant material standardand the applicable requirements of this specification. A manufacturing schedule shall be established andapplied in accordance with EN 2078.Product shall satisfy the requirements of the material standard and/or order and shall be free fromirregularitie
27、s prejudicial 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 alater stage, to contain such defects shall be rejected.Unless otherwise specified, the requirements in tables 1 and 2 shall a
28、pply in conjunction with those of therelevant material standard. Table 1 relates to lines 1 to 29 (inclusive) of the material standard and table 2relates to lines 30 onwards in which the sub-line format is also used. Lines 2 to 98 may also be opened inline 100 if the material standard details specif
29、ic qualification requirements. If a specific line number is notshown 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 technicalspecification.6.2 Qualification requirements
30、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 onthe first three batches, coming from three different ingots.6.3 Release requirements6.3.1
31、 Release testsRelease 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 materialstandard and/or order.The test samples shall be representative of the product.When required the manufacturer shall inf
32、orm the purchaser of the planned dates for extraction of samplesand 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 specificallyrequested by the purchaser, a particular inspection and/or t
33、est for release shall be carried out ifcorresponding acceptance criteria and/or values are stated in the applicable material standard, but see also6.3.5 “Capability clause“.6.3.2 RetestsIf the test procedure or test piece preparation is faulty, testing shall be re-applied at the original frequencyaf
34、ter rectification of the original cause of failure.When failure cannot be attributed to faulty testing, or test piece preparation, further test samples shall beselected at twice the original frequency from the product, one of which shall be that on which the originalresults were obtained unless alre
35、ady withdrawn by the manufacturer after suitable identification of the causeof failure. If all retest results are satisfactory, the batch shall be accepted. If one or more tests areunsatisfactory, the batch shall be: rejected, or 100 % retested and the conforming products accepted, or partially or f
36、ully re-heat treated if heat treatment can rectify the cause of the failure and tested as acompletely new batch except for chemical composition, for which redetermination of hydrogen contentis required . No product or test sample shall be re-heat treated more than twice.Copyright Association Europee

38、.4 Special testsSpecial tests may be required by the purchaser. In such cases, the nature of the test, method, frequency andtechnical requirements shall be specified on the order or inspection schedule and shall be mutually agreedby the manufacturer and purchaser.6.3.5 Capability clauseWhere capabil
39、ity clause is invoked and where sufficient statistical evidence exists, the test shall not becarried out (unless specifically requested by the purchaser). However, this in no way reduces the obligationsof the manufacturer to fulfil the requirements. If subsequent testing indicates that the product d
40、oes notcomply with the requirements, the batch shall be rejected.If sufficient statistical evidence does not exist, the test shall be carried out at a frequency agreed betweenthe manufacturer and the purchaser.6.3.6 Statistical process controlReduction in the extent of release testing, other than th
41、at defined in 6.3.5 above, may be negotiated with thepurchaser on the basis of appropriate statistical process control and/or statistical data.6.3.7 Inspection and test reportThe manufacturer shall furnish, with each delivery, a report conforming to the requirements of EN 2078stating the following:
42、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 and batch number; batch and/or test sample
43、s heat treatment condition; results of the tests and retests if any.6.4 TraceabilityEach product shall be traceable to the cast, production batch and/or heat treatment batch at all stages ofmanufacture, testing and delivery.Copyright Association Europeene des Constructeurs de Materiel Aerospatial Pr
