This part of this standard specifies the requirements for the ultrasonic testing of steel castings (with limited content of austenite) and the methods for determining internal discontinuities by the pulse echo technique. This part of this standard applies to the ultrasonic testing of steel castings which have usually received a grain refining heat treatment, and with wall thicknesses up to and including 600 mm.
