This European Standard specifies two methods for the determination of the content of soluble chromate in fertilizers and liming materials.
Method A specifies the determination of chromate after extraction with water by photometry. This method can be used to determine Cr(VI)-mass fractions in solids higher than 1 mg/kg.
Method B specifies the determination of chromate by alkaline digestion and ion chromatography with spectrophotometric detection. This method can be used to determine Cr(VI)-mass fractions in solids higher than 0,1 mg/kg.
NOTE 1  In case of reducing or oxidizing fertilizer matrix, no valid Cr(VI) content can be reported.
NOTE 2  The term fertilizer is used throughout the body of this European Standard and includes liming materials unless otherwise indicated.
