scope:
This International Standard specifies weighing methods for the preparation of calibraton gas mixtures for which the accuracy of the concentration of each component is better than 1%, whatever the values of the selected concentrations. It is applicable only to gaseous components which do not react between themselves or with cylinder walls, and to condensable components which are totally under the test conditions.
