Founding - Ultrasonic testing - Part 2: Steel castings for highly stressed components; German version EN 12680-2:2025
This document specifies the requirements for the ultrasonic testing of steel castings (with ferritic structure) for highly stressed components and the methods for determining internal discontinuities by the pulse-echo technique. An example for a highly-stressed cast component is a turbine housing, subjected to combined high static, cyclic and thermal load. This document is applicable to the ultrasonic testing of steel castings which have usually received a grain-refining heat treatment and which have wall thicknesses up to and including 600 mm.
