BS ISO 18852:2015规定了测定氮表面积（NSA）的方法 炭黑和其他橡胶复合成分，如硅和氧化锌，基于 Brunauer、Emmett和Teller（BET）的气体吸附理论也使用了多点测定 作为统计厚度表面积（STSA）的测定，也称为外部厚度 表面积。然而，STSA不适用于二氧化硅和氧化锌。该方法也可用于验证ISO 4652和 其他标准。交叉引用:ISO 4652:2012ISO 5794-1:2010ISO 9277:2010ISO 9298:1995购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS 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.Cross References:ISO 4652:2012ISO 5794-1:2010ISO 9277:2010ISO 9298:1995All current amendments available at time of purchase are included with the purchase of this document.
