Manufacturers batch number and production datec. Maximum fabric storage life calculated from the fiber manufacturing dated.
26、Manufacturers identificatione. List of fabric defects traceable to each individual rollf. Fiber designation of fiber manufacturer, batch number(s), bobbin numbersg. Test resultsNote: The kit expiration date shall be adjusted as appropriate in the label documentation attached to each kit. Kits shall
27、be provided with a minimum shelf life of 9 months. However, kits with a shorter remaining life can be supplied with customer agreement (See AMS2980/1, paragraph 4.2.2.5).The purchaser reserves the right to perform any of the inspections and/or tests required by this specification and may reject any
28、material which fails to meet the requirements.5.3 Fabric Manufacturer Additional Inspection5.3.1 Conformance to Weight and Dimensional RequirementsThe fabric rolls shall be inspected for conformance to weight and dimensional requirements in the relevant Appendix of PRI QPL AMS2980 and the requiremen
29、ts of paragraph 6.1.3.5.3.2 Inspection of PackagingThe manufacturer shall perform inspections as necessary to assure that the packaging, packing, preservation, and shipment requirements of paragraphs 6.1 and 6.2 are met.5.4 Fabric RetestIf batch release test data fails to meet the requirements of th
30、is PS and/or the Appendix of PRI QPL AMS2980, 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 preceding or the next roll. The material may be
31、 retested one time.
