This European Standard specifies a manual method for the determination of the concentration of fluorinated compounds expressed in HF. Two cases are presented: - first case: the measurand is the concentration of hydrofluoric acid and gaseous and bound to particulates fluorides, - second case: the measurand is the concentration of hydrofluoric acid and gaseous fluorides. Three analytical techniques are proposed: ionometry, spectrophotometry and ion-exchange chromatography. This European Standard specifies the performance characteristics to be determined and the performance criteria to be fulfilled when it is used as the Standard Reference Method (SRM) for periodic monitoring and for calibration or control of Automated Measuring Systems (AMS) permanently installed on a stack, for regulatory or other purposes. This document applies to more or less dust-laden flue gases whose HF concentration may vary between 0,1 mg/m3 and 10 mg/m3, at standard conditions of pressure and temperature. The quantification limit of the method is estimated at 0.1 mg/m3 for a sampled volume of 0.1 m3.
