26、trolled Copy, (c) BSI EN 2082-1:1989 BSI 11-19993 1 Scope This standard defines the general requirements for manufacture, inspection and testing of aluminium alloy forging stock and forgings. Particular requirements applicable to forging stock, pre-production forgings and production forgings are def
27、ined in EN 2082-2 and EN 2082-3 respectively. The three standards EN 2082-1, EN 2082-2 and EN 2082-3 define the inspection level and the sampling frequencies to be applied unless otherwise specified on the drawing, order or inspection schedule. 2 Field of application Unless otherwise specified on th
28、e drawing, order or inspection schedule this standard shall be applied when referenced in the relevant EN material standards. It is applicable to: Forging stock (EN 2082-2), Hand forgings including forged blocks and rings, die forgings and rolled rings (EN 2082-3), hereafter described as “forgings”.
29、 By agreement between the purchaser and the manufacturer, it may also be applied to other materials or delivery conditions not covered by EN standards. The agreements shall be formalized by reference to this standard on the drawing, order or inspection schedule. 3 References EN 2000, Aerospace serie

38、EN 2000. 6 Manufacture 6.1 Forgings shall be made from forging stock complying with the relevant EN material standard and EN 2082-2. 6.2 Unless otherwise specified, the method of manufacture to be employed shall be at the discretion of the manufacturer. 6.3 Conformance with the requirements of the p
39、urchaser shall be demonstrated by the manufacture and inspection and testing of pre-production forgings as required by EN 2082-3. 6.4 The products shall be supplied in the heat treatment condition specified in the material standard. If otherwise agreed, or if there are more than one heat treatment c
40、ondition in the material standard, the condition of supply shall be specified on the order or on the drawing. If a specific heat treatment temperature (value and tolerance) is stated, that temperature shall be mandatory. If a heat treatment temperature range is stated, a temperature within that rang
41、e reduced by the furnace tolerances shall be selected. Unless otherwise specified, the charge shall be maintained at the temperature subject to the tolerance of 5 C, for the period stated. 7 Traceability Each product shall be identifiable to its cast and batch at all stages of manufacture and delive

45、. The samples taken for analysis purposes shall be representative of the cast. The method of analysis shall be selected by the manufacturer, but in case of dispute, the method set out in the relevant ISO standard shall be used. If no ISO standard exists a fundamental method of chemical analysis shal

47、t samples cut from forgings, b) test samples forged integrally with the forgings, c) test samples forged separately from the same batch of forging stock as the forgings they represent. 9.2.2 The test samples and test pieces shall be marked in such a manner that their identity and orientation with re
48、spect to the product and the batch is maintained. 9.2.3 Test samples removed from finished forgings shall not be further worked. The preparation of test samples for the release of forging stock shall be carried out in accordance with EN 2082-2. 9.2.4 Should the test samples be taken as described in
49、clause 9.2.1 a), the purchaser shall specify the number of forgings to be cut up and shall define in the drawing or inspection schedule the location from which the test samples are to be taken. 9.2.5 Dimensions of test samples and test pieces representing forgings are to be agreed between manufacturer and purchaser and shall be stated on the drawing, order or inspection schedule. 9.3 Heat treatment of test samples 9.3.1 Test samples representing forgings to be supplied in any heat treated condition shall be he
