标准摘要
[中文适用范围]： 本标准规定了橡胶工业用炭黑类型和等级比表面积的两种测定方法： ——方法 A：自动气相色谱法（载气法）； ——方法 B：自动容量法。 这两种方法可能会得到有些不同的结果。 方法 A 和方法 B 的脱气程序不同，研究使用标准参考炭黑校正结果的可能性非常重要。 结果也可能与使用 ISO 18852 中指定的多点方法（这是首选方法）获得的结果不同。 这些方法不适用于多孔炭黑。 [外文原描述]： 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.
