Rubber compounding ingredients — Carbon black — Determination of specific surface area by nitrogen a...
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…
