LENGTH: Square and rectangular wire in straight lengths shall not vary from the ordered length by more than - 0, + 0.375 inch when specific lengths are ordered or by more than - 0, + 1.0 inch when specific lengths with ends or stock leng
16、ths with or without ends are ordered. No length tolerances are established for round, hexagonal, and octagonal wire. 5. STRAIGHTNESS: Square and rectangular wire having cross-sectional area of 0.010 square inch and over and thickness of 0.010 inch and over, when supplied in straight lengths, in roll
17、s, or on bucks, shall be of such straightness that the maximum edgewise curvature (depth of arc) shall be not greater than 0.500 inch in any 6 feet of length, or 0.083 inch x length in feet for shorter lengths. No straightness tolerances are established for round, hexagonal, and octagonal wire, for
18、square and rectangular wire under 0.010 square inch in cross-sectional area or under 0.010 inch thick or when supplied on reels or on stagger-wound rolls. 6. FLATNESS: No requirement established. 7. SPECIAL TOLERANCES: 7.1 If tolerances specified herein are plus and minus and if all plus or all minu
19、s are desired, use the sum of the plus and minus values specified, neglecting the signs. 7.2 If tolerances specified herein are all plus and if all minus are desired, use the same values specified. 7.3 If tolerances specified herein are all plus and if plus and minus are desired, halve the values sp
20、ecified. 8. 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 r
21、evision 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 Terms used in AMS are clarified in ARP1917. 8.3 Dimensions and properties in inch/pound units and Fahrenheit temperatures are primary; dimensions and properties in SI units and Celsius temperatures are shown as the approximate equivalents of the primary units and are presented only for information.
