Scope
Main technical content: This standard specifies the test method for the surface silanol groups of fumed silica (commonly known as fumed white carbon black), including the principles, reagents, instruments, and related provisions. This standard is applicable to the testing of the surface silanol group content of fumed silica. Among them, the acid-base titration method is suitable for testing the surface silanol group content of hydrophilic fumed silica. The reaction gas chromatography method is suitable for testing the surface silanol group content of both hydrophilic and hydrophobic fumed silica. This standard is not applicable to the testing of the surface silanol group content of fumed silica that contains substances capable of reacting with Grignard reagent in the sample.
