The microhardness method shall be conducted on a hardened, but untempered, specimen
24、 protected during heat treatment to prevent changes in surface carbon content. Depth of decarburization, when measured by the microhardness method, is defined as the perpendicular distance from the surface to the depth under that surface where there is no further increase in hardness. Such measureme
25、nts shall be far enough away from any adjacent surface to be uninfluenced by decarburization thereon. In case of dispute, the depth of decarburization determined via the microhardness traverse method shall govern.3.4.3.4.1 When determining the depth of decarburization, it is permissible to disregard
26、 local areas provided the decarburization of such areas does not exceed the above limits by more than 0.005 inch (0.13 mm) and the width is 0.065 inch (1.65 mm) or less.3.5 QualityTubing, as received by purchaser, shall be uniform in quality and condition and shall have a finish conforming to the be
27、st practice for high quality aircraft tubing. It shall be smooth and free from heavy scale or oxide, burrs, seams, tears, grooves, laminations, slivers, pits, and other imperfections detrimental to usage of the tubing. Surface imperfections such as handling marks, straightening marks, light mandrel
28、and die marks, shallow pits, and scale pattern will not be considered injurious if the imperfections are removable within the tolerances specified for wall thickness but removal of such imperfections is not required.3.5.1 Steel shall be aircraft quality conforming to AMS2301.3.5.2 When specified, th
29、e tubing, either with or without machining of the surface, shall be subjected to magnetic particle inspection in accordance with ASTM E 1444.

33、 and average grain size of each lot, and stating that the product conforms to the other technical requirements. This report shall include the purchase order number, heat and lot numbers, AMS6362G, size, and quantity. 4.4.2 When the product size is outside the range covered by Table 2 (See 1.1), the
34、report shall contain a statement to that effect.4.5 Resampling and RetestingShall be in accordance with AMS2370.5.
