This standard specifies the preparation method of impurity standard solutions for chemical analysis of inorganic chemical products. This standard is applicable to the preparation of solutions containing an accurate number of substances (elements, ions or molecules) in volume. It can be used for the determination of impurity content in inorganic chemical products and can also be used for other chemical products.
