BS EN 12680-1:2025

This standard BS EN 12680-1:2025 Founding — Ultrasonic testing is classified in these ICS categories:

• 77.140.80 Iron and steel castings
• 77.040.20 Non-destructive testing of metals

This document specifies the requirements for the ultrasonic testing of steel castings (with ferritic structure) for general purposes and the methods for determining internal discontinuities by the pulse-echo technique. 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 levels. This document does not apply to austenitic steels and joint welds. For highly stressed components EN 12680-2 is applicable.
