Scope

This document specifies a method for the determination of the chloride (Cl-) content by potentiometric titration. This method is applicable to growing media and soil improvers.

NOTE It is possible to use other analytical techniques (e.g. ion chromatography, discrete analyser, continuous flow analyser); in this case a validation is carried out by the laboratory for the procedure and data generated.
