DIN EN 17340:2018-12

This European Standard specifies a manual method for the determination of the concentration of fluorinated compounds expressed generally as gaseous and particulate hydrofluoric acid emitted to the atmosphere from ducts and stacks. Three analytical techniques are proposed: ionometry, spectrophotometry and ion-exchange chromatography.Two classes are presented:- general case: the measurand is the concentration of hydrofluoric acid and gaseous and bound to particulates fluorides,- special case: the measurand is the concentration of hydrofluoric acid and gaseous fluorides.
