ACKNOWLEDGMENTA vendor shall mention this specification number and its revision letter in all quotations and when acknowledging purchase orders.7. REJECTIONSProduct not conforming to this specification, or to modifications authorized by
25、purchaser, will be subject to rejection.8. NOTES8.1 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 specification. An (R) symbol to the left of the document ti
26、tle indicates a complete revision of the specification, including technical revision. Change bars and (R) are not used in original publications, nor in specifications that contain editorial changes only.8.2 Hardness should not be lower than 125 HBS/10/500 or 130 HBS/10/1000, determined in accordance
27、 with ASTM E 10. Hardness 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 param
28、eter review, and/or tensile property measurement on product with out-of-specification hardness may be necessary.8.3 Terms used in AMS are clarified in ARP1917.8.4 Dimensions and properties in inch/pound units and the Fahrenheit temperatures are primary; dimensions and properties in SI units and the
29、Celsius temperatures are shown as the approximate equivalents of the primary units and are presented only for information.8.5 Purchase documents should specify not less than the following: AMS 4121HForm and size of product requiredQuantity of product required.8.6 Similar SpecificationsAMS QQ-A-225/4
