Standard used to determine if check fixture gauge is acceptable

[jakhill]

Hey Team,

Got a question about calibrating check fixtures for automotive process. I am thinking that the normal is that the gauge is supposed to use on 10% of the tolerance allowed from the print and if it uses more, that it has to be signed off by management correct? Is there a standard that is connected to or is that just what most internal procedures use as normal? My apologies, but it has been a while since I was dealing with calibration on my own and cannot remember off the top of my head.

Are you referring to MSA being done on check fixtures?

Verification to the math data (CAD). If I remember correctly, when I verified these years ago, we used a standard of 10% of the tolerance, but I was not sure if that was to a specific standard or internal procedure.
