This Aerospace Standard (AS) provides a means for establishing a uniform method for specifying ultrasonic transducer performance, standardizing the measurement of transducer performance, and controlling allowable tolerances of transducer performance for the level specified on a purchase order or in a procurement specification. This standard identifies and defines transducer performance parameters and the method for measuring each parameter.
This specification covers the procedure for ultrasonic inspection of titanium-base alloy products 0.5 in. (13 mm) and over in cross sectional thickness.
This specification covers a stable, noncorrosive, water-soluble, highly-penetrating, fluorescent solution which may, but need not, be diluted with an appropriate amount of water for use.
