Apstrakt

This document specifies methods for:
—    determining the composition of a calibration gas mixture by comparison with appropriate reference gas mixtures;
—    calculating the uncertainty of the composition of a calibration gas mixture in relation to the known uncertainty of the composition of the reference gas mixtures with which it was compared;
—    checking the composition attributed to a calibration gas mixture by comparison with appropriate reference gas mixtures;
—    consistency testing and outlier search in suites of calibration gas mixtures of closely related composition.
NOTE 1    In principle, the method described in this document is also applicable to the analysis of (largely) unknown samples instead of prospective calibration gas mixtures (i.e. gas mixtures which are intended for use as calibration gas mixtures). Such applications, however, need appropriate care and consideration of additional uncertainty components, for example, concerning the effect of matrix differences between the reference gases used for calibration and the analysed sample.
NOTE 2    Comparison methods based on one- and two-point calibration are described in ISO 12963.
