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 1 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.
NOTE 2 This method has been validated in an interlaboratory study with specific products that were present on the market during the study (as included in Annex B, (composted bark, green compost, solid digestate, soil improver in pellet form and growing media blend 1 (peat + green compost + wood fiber + liming material + inorganic fertilizer)).
NOTE: If the word "harmonized" (marked in green) is not found in the field with the name of the directive, it means that the European standard is not cited in the OJEU.
