Abstract

ISO 6145-11:2005 specifies a method for the preparation of calibration gas mixtures by using electrochemical generation of a calibration component and introduction into a complementary gas flow. By alteration of the gas flow or the charge passed through the cell electrolyte, it is possible to change the composition of the gas mixture. The relative expanded uncertainty of the calibration gas content, U, obtained by multiplying the relative combined standard uncertainties by a coverage factor, k = 2, is not greater than 5 %.

The method described in ISO 6145-11:2005 is intended to be applied to the preparation of calibration gas mixtures in the volume fraction ranges (0,1 to 250) x 10^-6.
