MODEL APPROACH TO EVALUATION OF UNCERTAINTY IN MEASUREMENT: CASES NOT CONSIDERED IN GUM

S.V. Vodotyka, I.P. Zakharov, K.A. Klimova, N.S. Shevchenko
Annotations languages:

Measurement uncertainty evaluation for the quantity expressed in decibels is considered, results of calculation of the coverage factor fractional number of degrees of freedom are resulted, measurement uncertainty evaluation due to finite resolution of measuring instrument is considered, expanded uncertainty evaluation for correlation input quantities without use of effective number of degrees of freedom is carry out.
Keywords: standard uncertainty, expanded uncertainty, number of degrees of freedom
