Red bean production technical regulations
This document specifies two methods for the determination of the cadmium content of solid mineral fertilizers and rock phosphates after extraction with nitric acid. Organic fertilizers are not included in this standard. For detection in Method A flame-AAS is used. For detection in Method B ICP-OES is used. Due to the limits of quantification of the detection techniques, both methods are applicable for cadmium contents not less than 1 mg/kg.

This European Standard specifies a method for the determination of the release of the nutrients from coated slow-release fertilizers. pH-dependent hydrolysis and degradation by biological or microbial mechanisms are excluded. The specified method is only applicable to products releasing nutrients by means of a non-biological process (means for coating acting by physical mechanism); microbial attack on the coating and the consequences thereof are not measurable by the technique described.
