Scope
This document describes the principles, reagents or materials, instruments and equipment, experimental steps, and data processing of a general method for determining the water-insoluble matter in inorganic chemical products. This document is applicable to the determination of water-insoluble matter in inorganic chemical products. The glass sand crucible method specified in this document is suitable for determining the water-insoluble matter in non-alkaline products, the microporous filter membrane method (made of polytetrafluoroethylene) is suitable for determining the water-insoluble matter in products with a pH value of 2 to 13, and the Guss crucible method is suitable for determining the water-insoluble matter in all products.
