Scope
Main technical content: This document specifies the test method for silicon hydroxyl testing of vapor-phase silica dioxide (commonly known as vapor-phase white carbon black), including the principles, instruments, and related provisions of the testing steps. This document is applicable to the thermogravimetric analysis method for testing the total hydroxyl content of unmodified vapor-phase silica dioxide. This document is not suitable for silica dioxide with volatile substances at the test temperature.
