Tato norma specifikuje metodu pro stanovení vitamínu E v potravinách metodou vysokoúčinné kapalinové chromatografie (HPLC). Stanovení obsahu vitamínu E je uskutečňováno stanovením alfa-, beta-, gama- a delta-tokoferolu. Stanovení alfa-, beta-, gama- a delta-tokoferolů v roztoku vzorku je prováděno separací vysokoúčinnou kapalinovou chromatografií (HPLC) s následnou fotometrickou detekcí (v UV oblasti) nebo přednostně fluorimetrickou detekcí
