ISO 6145-5:2009 is one of a series of International Standards dealing with the various dynamic volumetric techniques used for the preparation of calibration gas mixtures. This part specifies a method for the continuous production of calibration gas mixtures from pure gases or gas mixtures using capillary calibration devices in single or multiple combinations (gas dividers).Single capillary systems can be used to provide gas mixtures where the minor component is in the range of volume fractions from 10-8 to 0,5.The relative expanded uncertainty of this technique is less than ï¿1/22 % (k = 2) relative. This application is used in industrial gas mixing panels
