Abstract

This International Standard specifies the fundamental structure and the most important performance characteristics of automated measuring systems for sulfur dioxide (SO2) to be used on stationary source emissions. The method allows continuous monitoring with permanently installed measuring systems of SO2 emissions. This International standard describes extractive systems and in situ (non-extractive) systems in connection with a range of analysers that operate using, for example, the following principles: — infrared absorption (NDIR); — Fourier transform infrared (FTIR) spectroscopy; — laser spectroscopic technique or tunable laser spectroscopy (TLS); — ultraviolet absorption (NDUV); — differential optical absorption spectroscopy (DOAS); — ultraviolet fluorescence (UVF); Other instrumental methods can be used provided they meet the minimum requirements proposed in this International Standard. AMS based on the principles above has been used successfully in this application for the measuring ranges described.
