This European Standard describes a manual method for sampling and determining SO2 content in ducts and stacks emitting to the atmosphere by two analytical methods: Ion chromatography and Thorin method.This European Standard is the Standard Reference Method (SRM) for periodic monitoring and for calibration or control of Automatic Measuring Systems (AMS) permanently installed on a stack, for regulatory purposes or other purposes. To be used as the SRM, the user shall demonstrate that the performance characteristics of the method are better than the performance criteria defined in this European Standard and that the overall uncertainty of the method is less th
