Rubber compounding ingredients — Carbon black — Determination of light transmittance of toluene extract

Standard Details

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.
