This International Standard provides 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,
comparing the composition of several calibration gas mixtures, e.g. for the purpose of comparing different methods of gas mixture preparation, or for testing consistency among gas mixtures of closely related composition.
NOTE 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, require 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.
