Abstract

This paper has the purpose to show how the instability of travelling standards can affect the results of an interlaboratory comparison program, and how to evaluate its influence in the determination of these results, in order to not compromise the assessing of a laboratory when En value is used for this purpose. In this work are presented and discussed five options of instability compensation of the travelling standard.
