Abstract
Adjustment of ultrasonic detection sensitivity with the aid of standar d test blacks with noncircular reflecting surfaces is discussed. The s hapes of reflecting surfaces and their angular position in the block w ith respect to the plane of entry of ultrasonic oscillations make it p ossible to use them for adjusting straight and oblique transducers. Co mposite test blocks for inspecting plane and rod-shaped materials are described.
