Hi everyone,
I work in an internal calibration lab, where we perform about 85% of the calibrations in house on instruments (calipers, mics, etc.) and equipment (ovens, water baths, etc.). We currently do not deal with MU on our calibrations that we perform in house. So this lead me to think about an approach for when it may be required.
Going back 50 years when the 4:1 rule was king, this is what we still go by at our company. I was thinking why would you want to waste time and money on a MU evaluation for a calibration that is at 20:1 ratio? So this started me thinking that maybe a possible solution would be to target those calibrations that are 5:1 or less for a MU evaluation?
