英文名称：Rubber compounding ingredients — Carbon black — Determination of specific surface area by nitrogen adsorption methods — Single-point procedures

标准范围

This International Standard specifies four methods for the determination of the specific surface area of types and grades of carbon black for use in the rubber industry:— method A using the Ni?Count?1 apparatus (Clause 3);— method B using the Areameter apparatus (Clause 4);— method C using gas chromatography (Clause 5);— method D using the Monosorb surface-area analyser (Clause 6).Somewhat different results might be obtained from the four methods. The degassing procedure used differs from method to method, 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.
