NOTE: The manufacturing schedule is the response
13、 of the manufacturer to orders placed by any purchaser. 3.3 Inspection schedule Document specifying additional inspection and/or testing requirements to those of the applicable EN aerospace standard for that semi-finished product. 3.4 Inspection and test report Document giving the results of all ins
14、pection and testing carried out on the semi-finished product in accordance with the applicable EN aerospace semi-finished product standard and any additional requirements specified on the drawing, order or inspection schedule. 4 Manufacturing schedule 4.1 General principles The preparation of a manu
15、facturing schedule is a mandatory requirement for semi-finished products qualification in accordance with EN 3042. Its preparation is under the responsibility of the manufacturer who has its property. On written request, the purchaser is entitled to collaborate to the drafting. It is used as the ref
16、erence document for semi-finished product qualification, under the conditions of accessibility and commercial secrecy defined in EN 3042. 4.2 Preparation The manufacturing schedule shall describe the manufacturing stages (including inspection and testing procedures) for the semi-finished product to
17、be manufactured, from the acquisition of raw materials through to the storage/delivery of the manufactured semi-finished product. 4.3 Approval 4.3.1 Initiai approval The manufacturing schedule shall be approved by the manufacturer in accordance with the internal procedures defined in his quality ass
18、urance system, as required by EN 2000. Where the manufacturing schedule has been defined in collaboration with the purchaser and/or has been verified by means of pre-production parts, it shall, additionally, be approved by the Design Authority of the purchaser. NOTE: In special cases, the manufactur
19、ing schedule can be frozen on purchasers written instructions. STD-AECMA PREN 2078-ENGL 1777 LOL23Ll 0034278 2b7 Page 5 prEN 2078: 1997 4.3.2 Monitoring of subsequent changes Changes which may significantly affect the quality of the semi-finished product shall be submitted for the written approval o
20、f the purchaser. After this approval, the manufacturer shall inform the Qualification Authority of the agreed changes. The Qualification Authority may record these changes (as an addition to the semi-finished product qualification file) or call for supplementary tests or for a new qualification. Whe
21、re the manufacturing schedule is frozen, any change shall be submitted for the purchasers written approval prior to implementation. 5 Inspection schedule 5.1 General principles The inspection schedule is used in the case of semi-finished products the requirements of which cannot be completely define
22、d by EN aerospace standards, typically forgings and castings. Its preparation is under the responsibility of the purchaser; it is implemented by the manufacturer, but remains the purchasers property. 5.2 Preparation The inspection schedule shall specify additional requirements for inspection and tes
23、ting not defined in the standards appearing on the order. It shall be linked to the drawing references of the semi-finished product. 5.3 Approval The inspection schedule shall be approved in accordance with the internal procedures defined in the purchasers quality assurance system, as required by EN
24、 2000. 6 Inspection and test report 6.1 General principles An inspection and test report shall be provided with each semi-finished product delivery. Its preparation is under the responsibility of the manufacturer, to support the inspection docum nt (see EN 10204) required on the order. 6.2 Preparati
25、on The inspection and test report shall give the results of the release inspection and/or testing in accordance with the relevant standards and, where relevant, purchasers additional instructions as stated in the order, drawing and inspection schedule. 6.3 Approval The inspection and test report shall be approved in accordance with internal procedures defined in the manufacturers quality assurance system as required by EN 2000.
