Founding - Ultrasonic examination - Part 1: Steel castings for general purposes
This European Standard specifies the requirements for the ultrasonic examination of steel castings (with ferritic structure) for general purposes and the methods for determining internal discontinuities by the pulse-echo tech-nique. This European Standard applies to the ultrasonic examination of steel castings 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 test procedure and recording levels. This European Standard does not apply to austenitic steels and joint welds.
