Scope

This Standard specifies the method summary, reagents and materials,
instruments and apparatuses, analysis steps, and result calculation FOR
inorganic chemicals for industrial use – general method for the determination of
water insoluble matter.
This Standard applies to the determination of water insoluble matter content in
inorganic chemical products. This Standard specifies the sand glass crucible
method for the determination of non-alkaline water insoluble matter. When
using this Standard to determine the water insoluble matter, the insoluble
matter’s mass that is obtained by the calculation of sample size and
specification value MUST not be less than 1 mg.

Summary	This standard specifies the determination of water- insoluble content of inorganic chemical products in general method approach feeds, reagents and materials, equipment, analysis steps and calculations. This standard applies to the determination of inorganic chemical products, water- insoluble content. This standard specifies the glass sand crucible method for the determination of non- alkaline substances in water insolubles. The determination of water insoluble matter by using the standard sample size and specifications of the resulting value is not less than the insoluble material only 1mg.
