LV breaker testing

[neher]

I have LV breaker.
I have tested these breaker with both primary and secondary injection testing and all pass.
Now there are setting on the breaker that need to change. example INST need to change from 12x to 4x. Or STPU need to change from 6 to 8 etc.

my question is do i need to retest the breakers?
is there a standard that spells this out?

Typically changing the settings on a breaker or relay does not warrant a retest unless there are firmware or logic changes that need testing.

Thank you, is there published information that supports this? I have looked and can not seem to find what i'm looking for
