27、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 safetyThe product in the delive

28、ry condition shall fulfil the current health and safety laws of the area of the countrywhere it is to be delivered.A product safety data sheet shall be available.6 Technical requirements6.1 GeneralThe product shall be manufactured in accordance with the requirements of the relevant material standard

29、and 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 fromirregularities prejudicial to the subsequent manufacture or us

30、e of this product.Notwithstanding 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 apply in conjunction with those of therelevant mater

31、ial 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 specific qualification requirements. If a specific line n

32、umber is notshown in tables 1 and 2, the requirement is stated in the material standard and/or order.6.2 Qualification requirementsQualification requirements when invoked by the material standard and/or order are detailed in tables 1 and 2.Unless otherwise agreed between the manufacturer and purchas

33、er the qualification phase shall be run onthe first 3 batches, coming from at least 2 casts.Copyright Association Europeene des Constructeurs de Materiel Aerospatial Provided by IHS under license with AECMANot for ResaleNo reproduction or networking permitted without license from IHS-,-,-Page 6prEN

34、4700-4: 20026.3 Release requirements6.3.1 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

35、.When required by the order the manufacturer shall inform the purchaser of the planned dates for extractionof 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 specificallyreques

36、ted by the purchaser, a particular inspection and/or test for release shall be carried out ifcorresponding acceptance criteria and/or values are stated in the applicable material standard, but see alsosection 6.3.5 “Capability clause“.6.3.2 RetestsIf any requirement is not met, retests shall be carr

37、ied out under the following conditions unless otherwisestated in the material standard or order.If the test procedure or test piece preparation is faulty, testing shall be re-applied at the original frequencyafter rectification of the original cause of failure, on a test sample located near the firs

38、t one.For wire with hardness results below the minimum or above the maximum value, the softest or hardest wire,as appropriate, shall be submitted to a tensile test. If the results comply with the specified tensilerequirements, all wire shall be accepted.When failure cannot be attributed to faulty te

39、sting, 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 already withdrawn by the manufacturer after suitable identification of the causeof failure. If all re

40、test 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 fully re-heat treated if heat treatment can rectify the cause of the failure and tested as acomple

41、tely new batch except for chemical composition and cleanness inspection. The reheat treatmentshall be stated on the release test certificate.For cleanness inspection, if the material fails the requirement the product may be cut back before retesting.6.3.3 RejectionAny failure to meet the requirement

42、s of the material standard shall be cause for rejection.6.3.4 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 manu

43、facturer and the purchaser.6.3.5 Capability clauseWhere the capability clause is invoked and where sufficient statistical evidence exists, the test need not becarried out (unless specifically requested by the purchaser). However, this in no way reduces the obligationsof the manufacturer to fulfil th

44、e requirements. If subsequent testing indicates that the product does 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 purchaser.Copyright Association Europe

46、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: manufacturers name

47、 and address and, if appropriate, identification of the plant; order number; material standard number; method of melting; delivery condition and metallurgical code of the product; quantity and dimensions; manufacturing and inspection schedule reference; cast and batch number; all heat treatment, inc
