This document specifies a manual method for the determination of the concentration of fluorinatedcompounds expressed in HF. Two cases are presented:

— first case: the measurand is the concentration of gaseous and bound to particulates fluorides;— second case: the measurand is the concentration of gaseous fluorides.

Three analytical techniques are proposed: ionometry, spectrophotometry and ion-exchangechromatography.

This document specifies the performance characteristics to be determined and the performance criteriato be fulfilled when it is used as the Standard Reference Method (SRM) for periodic monitoring and forcalibration or control of Automated Measuring Systems (AMS) permanently installed on a stack, forregulatory or other purposes.
