5、Superseding AMS2263D TolerancesNickel, Nickel Alloy, and Cobalt Alloy Tubing RATIONALEAMS2263E has been reaffirmed to comply with the SAE Five-Year Review policy.1. SCOPEThis specification covers established inch-pound manufacturing tolerances applicable to seamless and welded thin-wall aircraft tub

6、ing of nickel, nickel alloys, and cobalt alloys ordered to inch-pound dimensions. These tolerances apply to all conditions and are based on individual measurements, unless otherwise noted. The term “exclusive“ is used to apply only to the higher figure of a specified range. 2. DIAMETERMean diameter

7、is the average of two measurements taken at right angles to each other at the same section. Ovality is the difference between the maximum and minimum diameters of any one section of a tube. 2.1 Seamless, Cold Finished 2.1.1 Nickel-Copper Alloy, Annealed TABLE 1 - DIAMETER TOLERANCES, ANNEALED NICKEL
