The method is applicable to products having a calcium content equal to or greater than 0.002 % (m/m). The principle consists in titration of the calcium with a standard volumetric solution of the disodium salt of (ethylenedinitrilo)tetraacetic acid (EDTA disodium salt) in the presence of 2,2'-(ethylenedinitrilo)diphenol Äglyoxal-bis-(2-hydroxyanil)Ü as indicator, after elimination of impurities which may hinder the determination. - Replaces ISO Recommendation R 986-1969.
