Calibration interval optimization

Control your measurements and your budget!
  • Calibrate? Yes, but why and when?
  • Did you know that over 97% of measuring instruments are declared conform after the calibration?
  • What if these instruments were calibrated too soon? Are you sure that you have set the best-fit interval for your instrument base?
  • Do you know the usage limit (Maximum Permissible Error) for each of your instruments? Are they capable of checking the required tolerances in accordance with applicable standards?
Calibration interval optimization

Deltamu offers pragmatic solutions that will help you meet these challenges.

  • Applying calibration interval optimization methods to your instrument base
  • Skills transfer and provision of tools

Deltamu developed the FD X07-014 documentation published by AFNOR (2006), which describes three methods for optimizing measuring instrument calibration intervals: drift method, periodicity ratio method, and the OPPERET method (all available in the Optimu metrology software)

  • These methods generally enable companies to save at least 20% on their calibration budgets, by improving control over their measurement risks
  • Deltamu has been implementing these calibration interval optimization methods at its customers on a day-to-day basis for nearly 20 years now, as part of its MIM service offer

Why optimize?
  • To reduce direct and indirect costs
  • To control measurement quality
  • To ensure that the metrology function complies with the company's applicable reference standards
  • Deltamu developed the FD X07-014 documentation, published by AFNOR, describing the methods for optimizing calibration intervals.
  • Calculation methods recognized by ISO 10012, ISO 9001, IATF 16949, ISO 13485 quality standards.
  • Deltamu played a key role in developing the OPPERET method, used to determine best-fit equipment calibration intervals, and available in Optimu.
  • Deltamu has been implementing these calibration interval optimization methods at its customers on a day-to-day basis for nearly 20 years now, as part of its MIM service offer.

Using Deltamu's optimization method, we were able to adjust our instrument calibration levels, taking account of recent developments in these instruments and the critical nature of these measurements in our manufacturing process. We adjusted the intervals to their best-fit configuration on a case-by-case basis, thus enabling us to reduce the number of annual calibrations by 40% in 2012. Brousseval and Montreuil Foundries
