NOTCH sizes importance

As per AMS 2632 different notch hv different sizes but width is max fix 0.25mm

What is if width is more than that? Role of width dimension is more what happens?

Thanks for Ur valuable info.

If I my notch width is 0.40mm, can I use it or not ?
As per Specification it's max .25mm
Width deviations notches matters or not during angle beam scanning.

Technically, notch is a corner reflector and the ultrasonic reflection from 0.4 mm and 0.25 mm will be no different.

But depends how strict your client is. You should be able to justify 0.4 mm width. Depth is important for UT.
Width is important for eddy current.
