NOTES 8.1 Revision Indicator A change bar (l) located in the left margin is for the convenience of th

28、e user in locating areas where technical revisions, not editorial changes, have been made to the previous issue of this document. An (R) symbol to the left of the document title indicates a complete revision of the document, including technical revisions. Change bars and (R) are not used in original

29、 publications, nor in documents that contain editorial changes only. 8.2 Hardness of the T6 or T651 product should not be lower than 125 HBS/10/500 or 130 HBS/10/1000, determined in accordance with ASTM E10. Hardness has been used to verify that product is properly processed, but an “out-of-specific

30、ation 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 tensile property measurement on product with out-of-specification hardness may be necessa
