This European Standard specifies a method for the chromatographic determination of the iron chelated by
each individual ortho(hydroxy)-ortho(hydroxy) isomer of the chelating agents [o,o] EDDHA, [o,o] EDDHMA
and by HBED in fertilizers containing one or more of these substances, except for [o,o] EDDHMA and HBED
mixes. The method allows the identification and the determination of the total concentration of water soluble
iron chelates of these chelating agents. It does not determine the free form of the chelating agents.
This method is applicable to EC fertilizers covered by Regulation (EC) No 2003/2003 [4]. It is applicable to a
mass fraction of the metal chelated of at least 0,625 %.
