Length measurement possibility in metrology system of SR Yugoslavia based on the results of the seventh standards intercomparison measurement

Abstract

This article describes principles and methods of intercomparison measurement (Round-Robin), as well as the results and analysis of the seventh intercomparison measurement of standard length gauge blocks and standard cylinder in Yugoslavia. The analysis emphasizes the problem of correct application of used measurement methods, elaboration and presentation of results, and especially of their uncertainty. In the article the function dependence of reproducibility (uncertainty) and measured length of gauge blocks is given; and therefore the length measurement possibility in range of 100 mm in Metrology System of Yugoslavia based on the seventh intercomparison measurement.
