Annotation: Inter-laboratory comparisons for calibration laboratories (CL) are carried out by competent providers. For assessment the results of CL participation in such tests used the criteria set by the test coordinators for the quality of calibration for a particular type of measurement shall be used. The main task of the provider is to establish the reference value of the measured value and its uncertainty. Inter-laboratory comparisons by the CL are based on three main types of test organization, where the coordinators – providers (reference laboratories) can be: National Metrology Institutes (NMI); accredited CL; accredited providers that are not NMI or accredited CL. To check the consistency of the results of inter-laboratory comparisons using the χ2 criterion is proposed.


Keywords: inter-laboratory comparison, calibration laboratory, uncertainty of measurements, transmission sample, National Metrology Institute
