%RSD acceptance criterion between Karl Fischer measurements

Hello!

does anybody known how the acceptance criterion between 3 Karl Fischer measurements is defined. I guess that this depends on the level of water content, but until now I couldn't find a guideline.

Thank you

This should be covered by a product-specific method or SOP. Generally speaking, RSDs should be tighter when there's at least some moisture in a sample.
It is also a function of whether you're using Coulometric or other titration method.
