标准摘要
[中文适用范围]： 本文件规定了橡胶工业用炭黑中甲苯提取物透光率的测定方法，作为测量可提取物质引起的变色的一种手段。 透光率值提供了对炭黑表面上存在的甲苯可萃取物质引起的变色程度的估计。 该方法可能不适用于可萃取物含量高的炭黑。 [外文原描述]： This document specifies a method for the determination of the light transmittance of the toluene extract from carbon black for use in the rubber industry, as a means of measuring the discolouration caused by the extractable matter. The light transmittance value provides an estimate of the degree of discolouration caused by the toluene-extractable matter present on the surface of the carbon black. This method might not be applicable to carbon blacks with a high extractable-matter content.
