Руды железные. Определение гигроскопической влажности в аналитических пробах. Гравиметрический метод и метод Карла Фишера
Название (англ.):
Iron ores - Determination of hygroscopic moisture in analytical samples - Gravimetric and Karl Fischer methods
Описание (англ.):
Specifies two methods for the determination of 0,05 % (m/m) to 6 % (m/m) of hygroscopic moisture content in test samples. Either method is used where the analytical value of the constituent to be calculated to a dry sample basis is higher than 10 % (m/m) in the following types of ores:processed ores containing metallic iron (direct reduced iron), natural or processed ores in which the sulfur content is higher than 0,2 % (m/m), natural or processed ores in which the content of combined water is higher than 2,5 % (m/m). The result from the determination is not reported as part of the analysis of an ore sample.
