We calibrate basic inspection tools (Micrometers, Calipers, Height Gages) in house using lab grade Gage blocks traceable to NIST as our calibration standard.
We just had a Customer audit that resulted in a finding that we were not verifying if our gages meet 95% reliability to extend/reduce calibration intervals.
Can someone help by explaining how to determine 95% reliability for the small number of calibrations that we perform.
Please use a 0 - 1" mic calibration as an example.
They say I should have a procedure or instruction.
