I am not sure if this belongs here or in the ISO forum. Anyway after reviewing the system I am going to change our annual calibration of some 1100 gages we have in the system to every 2 years. I could do this as each one comes due and change the cal sticker then however, this would take a year to complete. I am wondering if I can just send out a directive to the departments stating that we will be adding 1 year to the due date currently on the calibration stickers of each gage. We would also note this in the software program ( Gagetrak) we use. Would the latter result in a non conformance in our next ISO audit?
