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

 M4 - Non automatic weighing instruments

 T2 - Digital thermometer

 V1 - Measuring bottles

 E5 - Electrical energy meters

 Q1 - Cold water meters

 F5 - Force transducers

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.
