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)! This reduced their risk (of "Out-of-Tolerance" instruments being used to inspect product), reduced their administrative costs (associated with performing "Out-of-Tolerance" impact analysis), and reduced their total annual cost for calibration services (fewer calibrations were performed)! |
