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 this specification. An (R) symbol to the left of the document title indicates a complete revisi
26、on of the specification, including technical revisions. Change bars and (R) are not used in original publications, nor in specifications that contain editorial changes only.8.2 Hardness should be not lower than 60HB/10/500 or 66HB/10/1000, determined in accordance with ASTM E 10. Hardness has been u
27、sed to verify that product is properly processed, but an out-of-range hardness number is not always indicative of product with out-of-specification tensile properties. Further analysis, including material composition verification, heat treat process parameter review, and/or tensile property measurem
28、ent on product with out-of-range hardness, may be necessary.8.3 Terms used in AMS are clarified in ARP1917.8.4 Dimensions and properties in inch/pound units are primary; dimensions and properties in SI units are shown as the approximate equivalents of the primary units and are presented only for inf
