EXPRESSION OF UNCERTAINTIES IN MEASUREMENT

Július Bajcsy

   The purpose of this paper is to demonstrate the basic principles of measurement evaluation of input quantities with uncertainties valid within EAL (European cooperation for Accreditation of Laboratories). The article sets down the principles and the requirements on the evaluation of the uncertainty of measurement in calibration the statement of this uncertainty in calibration certificates.

Keywords: measurand, standard deviation, uncertainty of measurement, standard uncertainty type-A, standard uncertainty type-B, combined standard uncertainty, expanded uncertainty
