Gas analysis. Preparation of calibration gas mixtures using dynamic methods - Thermal mass-flow controllersWhat is this standard about? ISO 6145 is a series of documents dealing with various dynamic methods used for the preparation of calibration gas mixtures. This document specifies a method for continuous preparation of calibration gas mixtures, from nominally pure gases or gas mixtures by use of thermal mass flow controllers. The method is applicable to preparation of mixtures of non reacting species, i. e. those which do not react with any material of
