This standard specifies the method for the determination of water resistance of glass particles at 98 °C. Water resistance is expressed by the volume of acid consumed by the alkali precipitated per unit mass of glass or converted into the mass of sodium oxide. Then classify according to the provisions of this standard. This standard applies to all types of glass.
