Line 9: Line 9:
 If M&TE calibration intervals were optimized based upon performance,​ optimal calibration intervals for some instruments might be 18 months, 24 months, or even longer. This results in immediate tangible cost savings. And while a few instruments may require shorter calibration intervals (e.g., 9 month intervals), immediate intangible savings are realized through the reduction of risks. If M&TE calibration intervals were optimized based upon performance,​ optimal calibration intervals for some instruments might be 18 months, 24 months, or even longer.

-One company I visited, had over 13,000 instruments in their calibration system. They'd contracted all of the calibrations with a metrology laboratory who "​optimized"​ their calibration intervals for them. The number of instruments found "​Out-of-Tolerance"​ dropped from 5% (650 instruments) per year to less than 0.5% (only 65 instruments)! +One company I visited, had over 13,000 instruments in their calibration system.
