3、007: Vormaterial This “Aerospace Series“ Prestandard has been drawn up under the responsibility of ASD-STAN (The AeroSpace and Defence Industries Association of Europe - Standardization). It is published for the needs of the European Aerospace Industry. It has been technically approved by the expert
4、s of the concerned Domain following member comments. Subsequent to the publication of this Prestandard, the technical content shall not be changed to an extent that interchangeability is affected, physically or functionally, without re-identification of the standard. After examination and review by
5、users and formal agreement of ASD-STAN, it will be submitted as a draft European Standard (prEN) to CEN (European Committee for Standardization) 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 E
6、N the status of a national standard and by withdrawing any national standards conflicting with the EN.

21、:2009 (E) 5 5 Health and safety 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 accord
22、ance with the requirements of 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 fro
23、m irregularities 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 a later stage, to contain such defects shall be rejected. Unless otherwise specified, the requirements in Tabl
24、es 1 and 2 shall 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 st
25、andard details 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 the technical specification. 6.2 Q
26、ualification requirements 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 on the first 3 batches. 6.3 Release requirements 6.3.1 Release t
27、ests 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 the material standard and/or order. The test samples shall be representative of the product. When required the manufacturer shall inform t
28、he 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 requirements for each line of the material standard. Unless otherwise specifically requested by the purchaser, a particular inspection and/or tes
29、t for release shall be carried out if corresponding acceptance criteria and/or values are stated in the applicable material standard, but see also in 6.3.5. prEN 4800-007:2009 (E) 6 6.3.2 Retests If the test procedure or test piece preparation is faulty, testing shall be re-applied at the original f
30、requency 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 twice the original frequency from the product, one of which shall be that on which the original results were obtain
31、ed 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 more tests are unsatisfactory, the batch shall be: rejected, or 100 % retested and the conforming products accepted, o
32、r 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 redetermination of hydrogen content is required. No product or test sample shall be re-heat treated more than twice. 6.3.3 Rejec
33、tion 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 nature of the test, method, frequency and technical requirements shall be specified on the order or inspection sched
34、ule 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 need not be carried out (unless specifically requested by the purchaser). However, this in no way reduces the obli
35、gations 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 sufficient statistical evidence does not exist, the test shall be carried out at a frequency agreed between the manufacturer
36、 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 basis of appropriate statistical process control and/or statistical data. 6.3.7 Inspection and test report The manufac
37、turer 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 the plant; order number; material standard number; delivery condition and metallurgical code of the product; quanti
38、ty and dimensions; prEN 4800-007:2009 (E) 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
39、 treatment batch at all stages of manufacture, testing and delivery. prEN 4800-007:2009 (E) 8 Table 1 Technical requirements for lines 1 to 29, where appropriate Frequency of testing Material standard line reference No Title Requirements Qualification Release 1 Material designation See EN 2032-1. Th
40、e 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 manufacturer unless otherwise stated in the material standard or order. In cases of dispute, the method of che
41、mical 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 certificate. 2 per cast 2 per cast 2 Chemical composition Specific requirements for hydrogen content: The h
42、ydrogen content shall be determined on each batch in the delivery condition in accordance with EN 3976. 1 per cast 1 per cast 3 Method of meltingMethod of melting shall consist of Cold Hearth (Electron Beam or Plasma Arc) and/or Consumable Electrode Vacuum Arc Melting. An initial non-consumable elec
43、trode 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 shall be purchased only from suppliers approved by the manufacturer and registered in his list of approv
44、ed 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 requirements shall be specified by the manufacturer who shall also establish the following procedures
45、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 prE
