Interlaboratory comparisons (ILC) or proficiency testing (PT) are common means of determining the testing performance of a laboratory. Proficiency testing is used by accreditation bodies to assess the technical competence of a laboratory and also by companies to ascertain the quality of measurement equipment and performance.

Area of measurements

CFI covers a wide range of measurement quantities, such as:

Electrical - Flow - Force - Length - Mass - Optical - Pressure - Temperature - Torque - Vacuum - Volume

Force

 F3 - Calibration of force transducers

 F4 - Calibration of force transducers

Mass

 M2 - Calibration of non automatic weighing instruments

 M3 - Calibration/subsequent verification of a truck scale

Torque

 TO3 - Reference for torque wrenches

 TO4 - Calibration of torque wrenches, screwdrivers

This is the website of CFI, the Nordic and Baltic centre for intercomparisons (proficiency testing) which has been developed for the purpose to assist calibration- and testing laboratories to secure their measurement claims according to ISO/IEC 17025.

CFI works over a wide area of different measurement quantities, instruments and accuracy levels, and our goal is to assist both measurement laboratories and industrial users.

Since there are many un-accredited laboratories that also need to secure their measurement capability, the services of this web site are also open to them.

The services offered are developed in cooperation between the NMI (National Metrology institutes) in the Nordic and Baltic countries.
