EN ISO 14719:2011 Chemical analysis of refractory material glass and glazes - Determination of Fe2+ and Fe3+ by the spectral photometric method with 1,10-phenanthroline (ISO 14719:2011)
This International Standard specifies a spectral photometric method with 1,10-phenanthroline for thequantitative 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 beextended 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.
