Gas analysis. Comparison methods for determining and checking the composition of calibration gas mixtures1 Scope 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
