Over deze norm
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.
