scope:
Specifies the gravimetric method for the preparation of reference gas mixtures in cylinders and is intended for the preparation of calibration gas mixtures whose target accuracy is defined a priori. It is applicable only to mixtures of gaseous, or totally vaporized components which do not react with each other or with the cylinder walls. A procedure is given for the preparation strategy that is based upon preset uncertainty levels of the composition of the final mixture. Multi-component gas mixtures and multiple dilution mixtures are included in this standard and are considered to be special cases of single component weighings.
