Finding ways to decrease the measurement uncertainty for participation in interlaboratory comparisons of measurement of mass

Abstract

As the title implies the article analyzes the factors that affect the result of evaluation of measurement uncertainty. It is specially noted need for participation of calibration laboratories in interlaboratory comparisons to obtain objective evidence of competence. The basic formulas for the estimation of measurement uncertainty in the calibration of measurement standards of mass are examined. The main activities undertaken of calibration laboratory for minimizing measurement uncertainty are described. These events have provided to the positive results in interlaboratory comparisons and provide traceability of calibration results to the national measurement standard of mass unit.
