标准摘要
[中文适用范围]： 本国际标准规定了一种测定炭黑和其他橡胶混合成分（如二氧化硅和氧化锌）的氮表面积 (NSA) 的方法，该方法基于布鲁诺尔、埃米特和特勒 (BET) 气体吸附理论，使用多点测定法以及统计厚度表面积 (STSA)（也称为外部表面积）的测定。然而，STSA 不适用于二氧化硅和氧化锌。该方法还可用于验证 ISO 4652 和其他标准中描述的“单点”程序。 [外文原描述]： ISO 18852:2015 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.
