Scope

This standard specifies a general method for determining water-insoluble substances by the weight method. This standard is applicable to the determination of water-insoluble substances in water-soluble solid chemical reagents. When determining water-insoluble substances according to this standard, the mass of the insoluble substances obtained by calculating the sampling quantity and specification value shall not be less than 1 mg. This standard is not applicable to the determination of water-insoluble substances in chemical reagents that are unstable in boiling water or corrode glass crucibles.
