This International Standard specifies a method for the determination of the active oxygen content of commercial washing powders. This method may be used for determining peroxyhydrates, for example sodium perborate; it should not be used for washing powders which contain, in addition to peroxyhydrates, products which react with acid permanganates under the analytical conditions. The method may be used in the presence of (ethylenedinitrilo) tetraacetic acid (EDTA) or other chelating agents of the same type, provided that the concentration of these products does not exceed 1% (m/m).
