标准简介：This part of ISO 6145 specifies a technique for the continuous production of calibration gas mixtures from pure gases or gas mixtures using capillary 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<up-8> to 0,5.
The relative repeatability of this technique is approximately 2 %. This application is used in industrial gas mixing panels for the production of specific gas atmospheres.
Gas dividers can be used to divide gas mixtures prepared from gases or gas mixtures into controlled proportions by volume. These devices are capable of dilutions in the range of volume fractions from 0,1 to 0,9 of the primary gas with a relative repeatability of better than 0,5 %.
Traceability of the gas mixtures produced by a gas divider can be achieved by comparison of a mixture at the higher and lower end of the range with gas mixtures related to national or international gas standards. An example is given in annex A.
