Norma je českou verzí evropské normy EN 1988-1:1998. Evropská norma EN 1988-1:1998 má status české technické normy. Tato evropská norma se skládá z následujících částí: Část 1 - Optimalizovaná Monier-Williamsova metoda, 2 - Enzymatická metoda. Siřičitan může být použit ke konzervaci potravin. Za účelem minimalizace možných negativních účinků na zdraví je v mnoha zemích používání siřičitanu v potravinách regulováno. proto bylo vyvinuto mnoho metod ke zjištění přítomnosti siřičitanu a stanovení jeho množství v různých druzích potravin. Tato norma popisuje destilační metodu stanovení obsahu siřičitanu (jako oxid siřičitý) v potravinách, kde jeho koncentrace je přibližně 10 mg.kg-1 a více. Princip metody i postup při provádění normalizované zkoušky je podrobně popsán. Norma tedy stanovuje základní postupy pro stanovení kontaminantu potravin významného pro hygienu výživy.
