中文名称：橡胶配合剂 多点氮表面积（NSA）和统计厚度表面积（STSA）的测定
英文名称：Rubber compounding ingredients — Determination of multipoint nitrogen surface area (NSA) and statistical thickness surface area (STSA)

标准范围
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 theBrunauer, Emmett and Teller (BET) theory of gas adsorption using a multipoint determination as wellas the determination of the statistical thickness surface area (STSA), otherwise known as the externalsurface 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 andother standards.
