Over deze norm
Specifies a method for the determination of up to approximately 2 milli-equivalents of tertiary amine oxide. Components which lose their basicity in reaction with acetic anhydride by forming an amide (e.g. primary and secondary amines) interfere. If present, these primary and scondary amines must be determined by a different procedure e.g. reaction with carbondisulfide. The method is applicable to solids or to aqueous solutions of the active material. The molecular mass of the amine oxide shall be known if its content is expressed as a percentage of mass.
