Scope

This standard specifies the method for determining the content of chelating agents in surfactants, with the content of chelating agents not exceeding 2% (by mass).
This standard is applicable to the determination of the content of ethylenediaminetetraacetic acid (EDTA) and its salts in surfactants. Before determining the content of other chelating agents or the content of EDTA when other chelating agents are present, the applicability of this method should be confirmed.
