Specifies weighing methods for gas mixtures for which the accuracy of the concentration of each component is better than 1 %, whatever the values of the selected concentrations. Applies only to gaseous components which do not react between themselves or with the cylinder walls, and to condensable components which are totally vaporized under the test conditions.
