Gas analysis - Comparison methods for determining and checking the composition of calibration gas mixtures (ISO/DIS 6143:2023)
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.

Analyse des gaz - Méthodes de comparaison pour la détermination et la vérification de la composition des mélanges de gaz d’étalonnage (ISO/DIS 6143:2023)
La présente Norme internationale décrit des méthodes pour
a) déterminer la composition d'un mélange de gaz pour étalonnage par comparaison avec des mélanges
appropriés de gaz de référence,
b) calculer l'incertitude de la composition d'un mélange de gaz pour étalonnage par rapport à l'incertitude connue
de la composition des mélanges de gaz de référence avec lesquels il a été comparé,
c) contrôler la composition attribuée à un mélange de gaz pour étalonnage par rapport aux mélanges appropriés
de gaz de référence,
d) comparer la composition de plusieurs mélanges de gaz pour étalonnage, par exemple afin de comparer
différentes méthodes de préparation de mélange de gaz, ou pour déterminer l'homogénéité parmi des
mélanges de gaz de composition proche.
NOTE En principe, la méthode décrite dans ce document est également applicable à l'analyse d'échantillons (largement)
inconnus plutôt que de mélanges de gaz pour étalonnage d'intérêt potentiel (c'est-à-dire mélanges de gaz destinés à être
employés commemélanges de gaz pour étalonnage). Toutefois, ces applications requièrent une attention particulière et la prise
en compte de composantes supplémentaires de l'incertitude, concernant, par exemple, l'effet des différences de matrice entre
les gaz de référence utilisés pour l'étalonnage et l'échantillon analysé.
