Chemical analysis of refractory material glass and glazes — Determination of Fe2+ and Fe3+ by the spectral photometric method with 1,10-phenanthroline - First Edition
N 14719
Annotation
This International Standard specifies a spectral photometric method with 1,10-phenanthroline for the quantitative determination of Fe2+ and Fe3+ in oxidic raw and basic materials for ceramics, glass and glazes, e.g. feldspar, kaolinites, clay, limestone, quartz refractory materials. This International Standard could be extended to other aluminosilicate materials, providing that uncertainty data is produced to support it. However, there might be problems in the decomposition of high-purity alumina and chrome ore samples.
The method is not suitable for reduced materials, such as silicon carbide, graphite-magnesia, etc.

Химический анализ стакана огнеупорного материала и глазури — Определения Fe2 + и Fe3 + спектральным светоизмерительным методом с с 1,10 фенантролинами - Первый Выпуск
Этот Международный стандарт определяет спектральный светоизмерительный метод с с 1,10 фенантролинами для количественного определения Fe2 + и Fe3 + в оксидном сырье и основных материалах для керамики, стекла и глазури, например, полевого шпата, каолинитов, глины, известняка, кварцевых огнеупорных материалов. Этот Международный стандарт мог быть расширен на другие материалы алюмосиликата, если те данные о неуверенности производятся для поддержки его. Однако могли бы быть проблемы в разложении высокочистых образцов глинозема и хромовой руды.
