       This International Standard specifies a flameless atomic ab-sorption spectrometric method for the determination of the mercury content of sodium hydroxide for industrial use. The method is applicable to liquid or solid products having mer-cury (Hg) contents greater than 0,02 mg/kg. NOTE —The alternative dithizone photometric method for the deter-mination of mercury content, specified in ISO 5992, is intended for use in laboratories where flameless atomic absorption equipment is not available.
