ifm's scope of calibration

ifm’s calibration laboratory offers ISO and A2LA calibrations. With the exception of free factory certificates, all calibration certificates must be ordered at the time the sensors are ordered. One certificate per sensors is required.


ISO calibration

An ISO calibration may only be performed by laboratories with a certified quality assurance system according to DIN EN ISO 9001:2015.

This is the only way we can offer you high quality calibrations.

The measuring equipment used for calibration are regularly recalibrated and traceable to the national standard of the German Physikalisch-Technische Bundesanstalt (PTB) or other national standards.

What is documented in our ISO calibration certificates?

  • Identification (object, manufacturer, type and serial number, customer, calibration certificate no., date, signature)
  • Clear description of the calibration standard used
  • Description of the ambient conditions
  • Description of the measuring equipment and the calibration procedure
  • All measuring results, by specifying the measuring points, unit and uncertainty
  • Remarks on the calibration results

ifm offers ISO calibration documents for pressure, flow and temperature sensors.

A2LA calibration

Like the DAkkS in Germany, the American Association for Laboratory Accreditation (A2LA) is the national institute for the accreditation of calibration laboratories in the United States.

Calibrations from A2LA-accredited laboratories are traceable to the NIST, the National Institute of Standards and Technology in the UnitedStates. Consequently, an A2LA calibration leads to internationally accepted measuring results.

ifm offers A2LA calibration documents for temperature sensors.
