24、rought metal products having a cross section thickness equal to 0.250 inch or greater. Round bar and billet may use AMS2628 techniques and equipment for billet over 4.5 inches using the acceptance criteria of Table 6 of AMS-STD-2154. Wrought metals include forging stock, forgings, rolled billet or p

25、late, extruded or rolled bars, extruded or rolled shapes, and parts made from them. Application of the methods in this standard is not intended for non-metals, welds, castings, or sandwich structures. 1.2.1 Wrought Aluminum Alloy Products Requirements for ultrasonic inspection of aluminum alloy wrou

26、ght products, except as noted below, shall be in accordance with ASTM B594: a. Ultrasonic inspection of machined aluminum alloy parts shall be in accordance with this standard. 1.3 Classification The ultrasonic inspection methods in this standard shall be classified as follows: 1.3.1 Type a.
