ISO 6145-6 - GAS ANALYSIS - PREPARATION OF CALIBRATION GAS MIXTURES USING DYNAMIC METHODS - PART 6: CRITICAL FLOW ORIFICES - THIRD EDITION Organization: ISO
Date: 2017-07-01
Description: This document specifies a method for the dynamic preparation of calibration gas mixtures containing at least two gases (usually one of them is a complementary gas) from pure gases or gas pre-mixtures using critical flow orifices systems. The method applies principally to the preparation of mixtures of non-reactive gases that do not react with any of the materials forming the gas circuit inside the critical flow orifices system or auxiliary equipment.

DS/EN ISO 6145-7 - GAS ANALYSIS - PREPARATION OF CALIBRATION GAS MIXTURES USING DYNAMIC VOLUMETRIC METHODS - PART 7: THERMAL MASS-FLOW CONTROLLERS Organization: DS
Date: 2011-03-21
Description: ISO 6145-7:2009 specifies a method for continuous production of calibration gas mixtures, containing two or more components, from pure gases or other gas mixtures by use of commercially available thermal mass-flow controllers. If this method is employed for the preparation of calibration gas mixtures, the optimum performance is as follows: the relative expanded uncertainty of measurement, U, obtained by multiplying the combined standard uncertainty by a coverage factor k = 2, is not greater than 2 %.
