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
E2 - Calibration of inductance
E3 - Calibration of capacitance
F10 - Verification and calibration of a uniaxial testing machine
L3 - Calibration of gauge blocks
M6 - Calibration of non automatic weighing instruments
TO8 - Torque transducers
T5 - Calibration of dry well calibrators
This is the website of CFI, a 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 was originally developed in cooperation between the NMI
(National Metrology institutes) in the Nordic and Baltic countries.
