REQUIREMENTS The prepreg to be delivered shall meet the general requirements in accordance with AMS3970/1 and the requirements of this PS and Appendix of PRI QPL AMS39
23、70 of the material to be purchased. 4.1 Defects Definition of defect description terms are per ASTM D 3990. Defects are defined in AMS3970/1. A defect area is defined as the length of the defect, if that defect exceeds specified limits, multiplied by the roll width. Thecumulative defective area in a
24、 roll shall not exceed 10% of the roll area. All defects within a length of one linear meter are counted as one defective area. _SAE INTERNATIONAL AMS3970/5 Page 4 of 11Each defect shall be identified and flagged with colored mark positioned on the roll. A continuous defect shall be identified with
25、a colored mark at the start and with a different colored mark at the end of the defect. Each roll shall have a defect record attached, recording the type, location and length of each defect (if any) in that roll. 4.2 Defect Credit Defective areas as defined in AMS3970/1 shall not be considered as pa
26、rt of the total length of the roll or its weight. The purchaser shall not be charged for any defective area. In addition, credit shall be given to the purchaser by the prepreg manufacturer for any manufacturing defect of the delivered material discovered during use that had not been previously ident
27、ified and credited. 5. RELEASE TESTING 5.1 General Products shall be manufactured in accordance with the manufacturing schedule of qualification and revisions agreed upon by the PRI. 5.2 Release Testing Release testing shall consist of tests given in Table 1. The test results shall demonstrate compl
28、iance with the technical requirements of this PS and the relevant Material Specification (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 prepreg batch delivered in accordance with
29、 this specification. Refer to 5.8 for the number of samples required based on the size of the batch. A minimum of one unit per batch of the physical properties tests (Table 1) shall be tested by an independent laboratory contracted by the manufacturer. The independent laboratory must be approved by
30、the PRI. 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 planned dates for the extrac
31、tion of samples and release testing, in order that these operations may be witnessed. _SAE INTERNATIONAL AMS3970/5 Page 5 of 11TABLE 1 - BATCH RELEASE FOR UNCURED NON-STRUCTURAL GLASS PREPREG - PHYSICAL AND PHYSIOCHEMICAL PROPERTIES id Property Number of Samples Per Unit1 Test Method 1.1 Mass per Un

NOTE: Test results shall meet the requirements specified in the relevant Appendix of PRI QPL AMS3970. 5.3 Release Test Certificate The manufacturer shall provid
34、e the purchaser with a test report certifying that the prepreg batch meets the general requirements in accordance with AMS3970/1 and the requirements of this PS and Appendix of PRI QPL AMS3970 of the material to be purchased. The prepreg release test report shall contain at least the following: Spec
35、ificationManufacturers batch number and production date Manufacturers identification List of defects traceable to each individual roll Fiber designation of fabric manufacturer, batch number(s), bobbin numbers Test results 5.4 Retest If batch release test data fails to meet the requirements of this P
36、S 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 the next roll. The material may be retest
37、ed 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 samples shall be selected at twice the original
38、 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 results are unsatisfactory, the batch sh
39、all be: a. Rejected, or b. 100% retested and the conforming products accepted _SAE INTERNATIONAL AMS3970/5 Page 6 of 115.5 Rejection Any failure of the prepreg to meet the batch release requirements of this specification shall be cause for rejection of the material. Any defect not detected during ac
40、ceptance 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 this specification. 5.6 Warranty Each production batch or shipment, whic
41、hever 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 that
42、 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. Audits wil
43、l 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 between
44、 the PRI and the manufacturer if required. 5.8 Sampling 5.8.1 Sampling - Physical Tests A sample unit is defined as a quantity of impregnated material with a surface area not exceeding 175 m2, independent of the width and the mass per unit area of that impregnated material. 5.8.2 Sampling - Physioch
45、emical Tests Physiochemical tests shall be executed on the first and last roll (unit) of each batch. 6. PREPARATION FOR DELIVERY 6.1 Packing 6.1.1 General Prepreg shall be packaged in clean, dry, shipping containers so constructed as to ensure acceptance by common or other carrier for safe transport
46、ation 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 Prepreg Rolls Each roll shall be individually packaged in a sealed moisture-proof bag of non-contaminating material (polyethylene or equivalent) with minimum thickness o
47、f 0.15 mm. The packaging shall be such that the material shall not deform under its own mass and shall meet the requirements of this specification after delivery.
