43、 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 document. An (R) symbol to the left of the document title indicates a complete revision of the document, including technical

44、 revisions. Change bars and (R) are not used in original publications, nor in documents that contain editorial changes only. 8.2 Terms used in AMS are clarified in ARP1917 and as follows: 8.2.1 A double flare is similar to a standard single flare except that the flare is folded back on itself such t

45、hat the cut edge is inside the flare near the ID of the tube. Definitions and illustrations of single flaring are shown in MS 33584; double flaring is defined and illustrated in MS 33883. 8.3 Dimensions and properties in inch/pound units and the Fahrenheit temperatures are primary; dimensions and pr

46、operties in SI units and the Celsius temperatures are shown as the approximate equivalents of the primary units and are presented only for information.
