Fertilizers - Determination of the complexed micro-nutrient content and of the complexed fraction of micro-nutrients
N EN 15962
Annotation
This European Standard specifies a general method for the determination of the micronutrients complexed by complexing agents in fertilizers. The method allows the determination of the total concentration of each complexed micronutrient in complexes after subtraction of the chelated micro-nutrients content, but it does not identify the individual complexing agents.
This procedure concerns EC-fertilizers which contain complexed micro-nutrients covered by Regulation (EC) No 2003/2003. The method is applicable to a mass fraction of the metal complexed of at least 0,07 %, 0,006 % and 0,035 % of Fe, Mn and Zn respectively (see [2]). A lower limit of quantification has not been established for Cu and Co.

Удобрения - Определение объединенного содержания микронутриента и объединенной части микронутриентов
Этот европейский стандарт определяет общий метод для определения микронутриентов, объединенных путем объединения агентов в удобрениях. Метод позволяет определение общей концентрации каждого объединенного микронутриента в комплексах после вычитания chelated содержания микронутриентов, но это не идентифицирует отдельных агентов объединения.
