EN 12680-2 - NDT Ultrasonic examination. Founding

[Garlik]

Hello.

The scope of this standard is for "highly stressed components". Where is the limit? When can I know if one material is higly stressed or not? When do I need to apply the standard 12680-1 (for general purposes) or 12680-2 (highly stressed components)?

thanks and regards.

Some information is available as follows:

Abstract for BS EN 12680-2
This European Standard specifies the requirements for the ultrasonic examination of steel castings (with ferritic structure) for highly stressed components and the methods for determining internal discontinuities by the pulse echo technique.

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.
