This document provides methods for<\/p>\n
calibrating an instrument with one or two calibration gas mixtures,<\/p>\n<\/li>\n
determining the composition of a gas sample, and<\/p>\n<\/li>\n
evaluating the uncertainty of the composition of the gas sample in relation to the uncertainty of the composition of the calibration gases used and the contribution of the measurement process.<\/p>\n<\/li>\n<\/ul>\n
This document sets requirements to, and acceptance criteria for, the utilization of different measurement calibration designs with a limited (i.e. minimum) number of calibration gas mixtures used in calibration.<\/p>\n
The methods in this document are described for amount-of-substance fractions, but are also applicable for other composition quantities (such as mass fractions, volume fractions or concentrations).<\/p>\n
