Hi I am the quality engineer and calibration supervisor of our QS9000 registerd company. Up until now we had performed only Gage R&R and calibrations on our gages and equipment. Our auditor has since asked us to do some form of repeatability test before calibration. I have looked in the MSA book for QS9000 at the examples of Bias, Stability and Repeatability. I believe what he is looking for is actually more along the lines of Stability or Bias. My problem is what is concidered an acceptable percentage. I can not find anything in the MSA manual.
