This Part of GB/T 7223 specifies the requirements for the ultrasonic examination of steel castings (non-austenitic steel) for general purposes, and the methods for determining internal discontinuities by the pulse-echo technique. This Part is applicable to the ultrasonic examination of steel castings (non-austenitic steel) which have usually received a grain-refining heat treatment and which have wall thicknesses up to and including 600 mm. For greater wall thicknesses, special agreements apply with respect to the test procedure and recording levels. This Part does not apply to austenitic steels and joint welds.
