This International Standard specifies a gravimetric method for the preparation of calibration gas mixtures in
cylinders of which the target accuracy of the composition has been pre-defined. 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 a method of preparation based on requirements for the final gas mixture composition to be within preset
levels of uncertainty. Multi-component gas mixtures (including natural gas) and multiple dilution mixtures are
included in this International Standard and are considered to be special cases of the single component gravimetric
preparation method.
This International Standard also describes the procedure for verifying the composition of gravimetrically prepared
calibration gases. Provided rigorous and comprehensive quality assurance and quality control procedures are
adopted during the preparation and validation of these gravimetric gas mixtures, calibration gases of the highest
accuracy can be obtained for a wide range of gas mixtures, in comparison with other methods of preparing such
gases.
