WARNING — Persons using this document should be familiar with normal laboratory practice. This document does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices.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.All current amendments available at time of purchase are included with the purchase of this document.
