| Predmet normy: | 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. Highly-stressed means for example: — High material utilization (close to Rp0,2) — High static and cyclic load — For fail-safe assessment, requiring a fracture-mechanic assessment An example for a highly-stressed cast component is a turbine housing, subjected to combined high static, cyclic and thermal load. Purchasers determine if components are highly stressed based on the need for performance or safety. For lower-stressed cast components for general purposes, EN 12680-1 applies. 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. For greater wall thicknesses, special agreements are applicable with respect to test procedure and recording ... |
