Rubber. Assessment of carbon black and carbon black/silica dispersion. Rapid comparative methods. | Status: Current, Under review

1 Scope This International Standard specifies qualitative visual methods for the rapid and comparative assessment of the degree of macrodispersion of carbon black and carbon black/silica in rubber. Ratings are made relative to a set of standard reference photographs, and the results are expressed on a numerical scale from 1 to 10. In addition, a method is given for rating the presence of large agglomerates on a numerical scale (ratings 1 to 10).
