This International Standard specifies a 1,10-phenanthroline photometric method for the determination of the iron content of sodium hydroxide for industrial use.
This method is more sensitive and more widely used than the 2,2′-bipyridyl method which was specified in ISO/R 983:1969.
The method is applicable to products having iron contents equal to or greater than 0,5 mg/kg.
