REQUIREMENTS The film adhesive to be delivered shall meet the general requirements in accordance with AMS3970/1 and the requirements of this PS and Appendix of PRI QPL AMS3970 the ma

23、terial to be purchased. 4.1 Defects Defects are defined in AMS3970/1. Each defect shall be identified and flagged with colored mark positioned on the roll. A continuous defect shall be identified with a colored mark at the start and with a different colored mark at the end of the defect. Each roll s

24、hall have a defect record attached, recording the type, location and length of each defect (if any) in that roll. SAE INTERNATIONAL AMS3970/4A 4 of 10_4.2 Defect Credit Defective areas as defined in AMS3970/1 shall not be considered as part of the total length of the roll or its weight. The purchase

25、r shall not be charged for any defective area. In addition, credit shall be given to the purchaser by the film adhesive manufacturer for any manufacturing defect of the delivered material discovered during use that had not been previously identified and credited. 5. RELEASE TESTING 5.1 General Produ

26、cts shall be manufactured in accordance with the manufacturing schedule of qualification and revisions agreed to by the PRI. 5.2 Release Testing Release testing shall consist of tests given in Table 1 and Table 2. The test results shall demonstrate compliance with the technical requirements of this

27、PS and the relevant MS and Appendix of PRI QPL AMS3970. Release testing shall be the responsibility of the manufacturer. The test samples extracted should be representative of the entire film adhesive batch delivered in accordance with this specification. Refer to 5.8 for the number of samples requi

28、red based on the size of the batch. The purchaser reserves the right to perform any of the inspections and/or tests required by this specification and may reject any material which fails to meet the requirements. When required, the manufacturer shall inform the purchaser or his chosen agent of the p

29、lanned dates for the extraction of samples and release testing, in order that these operations may be witnessed.

32、MS3970. SAE INTERNATIONAL AMS3970/4A 5 of 10_5.3 Release Test Certificate The manufacturer shall provide the purchaser with a test report certifying that the film adhesive batch meets the general requirements in accordance with AMS3970/1 and the requirements of this PS and Appendix of PRI QPL AMS397

33、0 of the material to be purchased. The film adhesive release test report shall contain at least the following: SpecificationManufacturers batch number and production date Manufacturers identification Material and delivery condition Quantity in batch Test results 5.4 Retest If batch release test data

34、 fails to meet the requirements of this PS and/or Appendix of PRI QPL AMS3970, a review of all test results, test procedures, specimen manufacturing and test specimen(s) shall be performed. If a cause for discrepancy is found, retests shall be performed on the same roll and either the preceeding or

35、the next roll. The material may be retested one time. The results of the original test, together with those of the retest and the reasons for the first failure shall be included in the test report. When failure cannot be attributed to faulty testing, or test piece preparation, additional test sample

36、s shall be selected at twice the original frequency from products on which the incorrect results were obtained unless already withdrawn by the manufacturer after suitable identification of the cause of failure. If all retest results are satisfactory, the batch shall beaccepted. If one or more retest

37、 results are unsatisfactory, the batch shall be: a. rejected, or b. 100% retested and the conforming products accepted 5.5 Rejection Any failure of the film adhesive to meet the batch release requirements of this specification shall be cause for rejection of the material. Any defect not detected dur

38、ing acceptance inspection, but which becomes apparent during the subsequent use of the material, shall be cause for rejection of the unused portion of the batch, provided such a defect is cause for rejection under the requirements of the specification. 5.6 Warranty Each production batch or shipment,

39、 whichever is smaller, of the qualified material submitted to this PS shall be warranted through a release test certificate by the manufacturer and/or supplier to meet the requirements of this PS and the relevant MS and Appendix of PRI QPL AMS3970. The manufacturer and/or supplier shall also warrant

40、 that the raw materials and processes used in manufacture of the subsequent production batches or shipment are the same in type, form and quality as those used for the qualification. 5.7 Audit PRI retains the right to audit the manufacturing process of a qualified product at certain intervals. Audit

41、s will be performed in accordance with the Appendix of PRI QPL AMS3970. The manufacturer shall make available all necessary documents, records and supporting information with regard to the material manufacture for inspection by representatives of PRI. A non-disclosure agreement can be established be

42、tween the PRI and the manufacturer if required. SAE INTERNATIONAL AMS3970/4A 6 of 10_5.8 Sampling 5.8.1 Sampling for Physical Tests For inspection and test purposes each batch of film adhesive shall be divided into units of one roll (as delivered). 5.8.2 Sampling for Physico/Chemical Tests Physico/c

43、hemical tests shall be performed on the first and last unit of each batch of film adhesive. 6. PREPARATION FOR DELIVERY 6.1 Packing 6.1.1 General Film adhesive shall be packaged in clean, dry, shipping containers so constructed as to ensure acceptance by common or other carrier for safe transportati

44、on to the place of delivery specified by purchase order or contract and to retain the requirements of the TS and this PS. 6.1.2 Film Adhesive Rolls Each roll shall be individually packaged in a sealed moisture-proof bag of non-contaminating material (polyethylene or equivalent) with minimum thicknes
