4、on of Aerospace Industries - Standardization). It is published for the needs of the European Aerospace Industry. It has been technically approved by the experts of the concerned Domain following member comments. Subsequent to the publication of this pre-standard, the technical content shall not be c

5、hanged to an extent that interchangeability is affected, physically or functionally, without re-identification of the standard. After examination and review by users and formal agreement of AECMA-STAN, it will be submitted as a draft European Standard (prEN) to CEN (European Committee for Standardiz

6、ation) for formal vote and transformation to full European Standard (EN). The CEN national members have then to implement the EN at national level by giving the EN the status of a national standard and by withdrawing any national standards conflicting with the EN.

9、material standards for aerospace applications. The general organization of this series is described in EN 4258. 1 Scope This standard defines the requirements for the ordering, manufacture, testing, inspection and delivery of aluminium alloy wrought forging stock ( produced by extrusion or hot rolli

10、ng) and cast forging stock. It shall be applied when referred to and in conjunction with the EN material standard, normally when the forging stock manufacturer is Nt the producer of the corresponding forgings. 2 Normative references This European Standard incorporates by dated or undated reference p

For definitions specific to aluminium alloys, see EN 12258-1. 4 Wording of order The order shall clearly indicate: - quantities to be supplied; - dates of delivery; - material standard number; - del

19、ivery condition; - dimensions and tolerances or reference to an appropriate dimensional standard; - forwarding address; - nature and type of packing, if required; - definition and frequency of any special tests and their retest procedures, if required. 5 Health and safety The product in the delivery

20、 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 of the relevant material stan

21、dard and the applicable requirements of this technical specification. A manufacturing schedule shall be established and applied in accordance with EN 2078. The product shall satisfy the requirements of the material standard and/or order and shall be free from irregularities prejudicial to the subseq

22、uent manufacture or use of this product. Notwithstanding previous acceptance complying with the material standard and this technical specification, 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 s

23、hall apply in conjunction 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 detai

24、ls specific qualification 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 this technical specification. Page 5 prEN 4400

25、-6:2003 6.2 Qualification requirements See line 100 in Table 2 of this technical specification. 6.3 Release requirements 6.3.1 Release tests Release testing shall be the responsibility of the manufacturer. The purchaser reserves the right to perform any of the inspections and/or tests required by th

26、e 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 dates for extraction of samples and release testing in order that these operations may be witnessed. Tables 1 and 2 detail the requirem

27、ents for each line of the material standard. Unless otherwise 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 section 6.3.5 “C

28、apability clause“. 6.3.2 Retests If any requirement is not met and 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 on a test sample located near the original. When failure cannot be

29、 attributed to faulty testing or test piece preparation, further test samples shall be selected at 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 c

30、ause of fa i I u re. If all retest results are satisfactory, the batch shall be accepted. If one or more tests are unsatisfactory, the batch shall be rejected. 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 test

31、s may be required by the purchaser. In such cases, the nature of the test, method, frequency and technical requirements shall be specified on the order or inspection schedule or forging drawing and shall be mutually agreed by the manufacturer and the purchaser. 6.3.5 Capability clause Where sufficie

32、nt statistical evidence exists that the required acceptance criteria can be routinely achieved (usually tensile testing of forging stock) and with the agreement of the purchaser, the “capability clause“ may be invoked when and where stated in the material standard and/or this technical specification

33、. In such cases, the test need not be carried out for release purposes 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 requirement

34、s, the batch shall be rejected. If the “capability clause“ is invoked but sufficient statistical evidence does not exist, the test shall be carried out for release purposes at a frequency agreed between the manufacturer and purchaser. Page 6 prEN 4400-6:2003 6.3.6 Statistical process control Reducti

35、on 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 statistical data. 6.3.7 Inspection and test report The manufacturer shall furnish, with each delivery, a report conforming t

36、o the requirements 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 sc

37、hedule reference, if appropriate; - cast and batch number; - batch and/or test sample heat treatment, if required by the purchaser; - results of all tests and chemical analysis and re-tests, if any. 6.4 Traceability Each product shall be traceable to the cast, production batch and/or heat treatment

38、batch at all stages of manufacture, testing and delivery. Page 7 prEN 4400-6:2003 c. v) o o 3 W g Q) O c O v) 5 u- .- o L Page 11 prEN 4400-6:2003 m C = u) a O i o C a S v L * ic e!
