QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for Inspection The vendor of the product shall supply all samples for vendors tests and shall be responsible for the performance of all required tests. Purchaser reserves the ri

22、ght to sample and to perform any confirmatory testing deemed necessary to ensure that the product conforms to specified requirements. 4.2 Classification of Tests All tests are acceptance tests and except for composition, shall be performed on each inspection lot. 4.3 Sampling and Testing Shall be in

23、 accordance with AMS2355. 4.4 Reports The vendor of the product shall furnish with each shipment a report stating that the product conforms to the composition and tolerances, and showing the numerical results of tests on each lot to determine conformance to the tensile property requirements.

NOTES 8.1 A change bar (|) located in the left margin is for the convenience of the user in locating areas where technical revisions, not editorial changes, have been made to the previous issue of a document. An (R) symbol to the left of the document ti

28、tle indicates a complete revision of the document, including technical revision. Change bars and (R) are not used in original publications, nor in documents that contain editorial changes only. 8.2 Hardness should be not lower than 90 HB/10/500 or 95 HB/10/1000 in accordance with ASTM E 10. Hardness

29、 has been used to verify that product is properly processed, but an “out-of-specification hardness number” is not always indicative of product with “out-of-specification tensile strength”. Further analysis, including material composition verification, heat treat process parameter review, and/or tens

30、ile property measurement on product with out-of-specification hardness, may be necessary. 8.3 Terms used in AMS are clarified in ARP1917. 8.4 Purchase documents should specify not less than the following: AMS4118L Form and size of product required Quantity of product required . 8.5 Similar Specifications AMS-QQ-A-225/5 or AMS-QQ-A-225/5, Tempers -T4 and -T451, are listed for information only and shall not be construed as an acceptable alternates unless all requirements of this AMS are met.
