Annotation of standard text ČSN P CEN/TS 17778 (654941):
This document is applicable to fertilizing products, which are classified as PFC 1(A) and PFC 1(B) or the PFC 1(A) and PFC 1(B) component in PFC 7 of Regulation (EU) 2019/1009. However, the present method was not validated on blends. This document specifies a method for the determination of hexavalent chromium (chromium (VI)) in organic and organo-mineral fertilizers. The method described is suitable to quantify the chromium (VI) content in organic and organo-mineral fertilizers down to 2 mg/kg dry matter. The results obtained from this method are strictly dependent on the extraction conditions. Results obtained by using other extraction procedures (extraction solution, pH of the extraction solution, extraction time, extraction temperature etc.) are not comparable with the results produced by the procedure described in this document
