本文件规定了测定橡胶工业用炭黑类型和等级比表面积的两种方法: -方法A:自动气相色谱法（载气法）； -方法B:自动容量法。 这两种方法的结果可能有所不同。脱气程序在方法A和方法B之间有所不同，重要的是研究使用标准参考黑校正结果的可能性。 结果也可能不同于使用ISO 18852中规定的多点方法获得的结果，该方法是首选方法。 这些方法不适用于多孔炭黑。

This document specifies two methods for the determination of the specific surface area of types and grades of carbon black for use in the rubber industry: — method A: automatic gas chromatography method (carrier gas method); — method B: automatic volumetric method. Somewhat different results might be obtained from the two methods. The degassing procedure differs between method A and method B, and it is important to investigate the possibility of correcting the results by using standard reference blacks. The results might also differ from those obtained using the multipoint method specified in ISO 18852, which is the preferred method. These methods are not applicable to porous carbon blacks.
