This standard specifies a method for determining the content of water-soluble matter in precipitation hydrated silica produced by sulfuric acid method by conductivity method. It is suitable for precipitation hydrated silica produced by sulfuric acid process. The products of Miscellaneous production method can be referred to for use. The standard indirectly determines the content of soluble salts by measuring the conductivity of the solution, providing an effective detection means for the quality control of rubber compounding agents. The standard describes in detail the requirements for the use of reagents, materials and instruments to ensure the accuracy and conformity of the test results.
