Scope
This International Standard specifies a method for the determination of the nitrogen surface area (NSA)
of carbon blacks and other rubber compounding ingredients, like silicas and zinc oxides, based on the
Brunauer, Emmett and Teller (BET) theory of gas adsorption using a multipoint determination as well
as the determination of the statistical thickness surface area (STSA), otherwise known as the external
surface area. STSA, however, is not applicable to silica and zinc oxide.
The method can also be used for verifying “single-point” procedures described in ISO 4652 and
other standards.
