ACKNOWLEDGMENT Supplier shall mention this specification

    37、number and its revision letter in all quotations and when acknowledging purchase orders. SAE AMS3275C Page 6 of 6 7. REJECTIONS Sheet not conforming to this specification, or to modifications authorized by purchaser, will be subject to rejection. 8. NOTES 8.1 A change bar (|) located in the left mar

    38、gin 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 title indicates a complete revision of the document, including technical revision. Change bars and

    39、(R) are not used in original publications, nor in documents that contain editorial changes only. 8.2 Dimensions and properties in inch/pound units and the Fahrenheit temperatures are primary; dimensions and properties in SI units and the Celsius temperatures are shown as the approximate equivalents of the primary units and are presented only for information. 8.3 IRM 903 is available from Calumet Lubricant Company, Indianapolis, IN, telephone (317) 328-5660.
