BS 5293-20:1992

This standard BS 5293-20:1992 Sampling and testing carbon black for use in the rubber industry is classified in these ICS categories:

• 83.040.20 Rubber compounding ingredients

This International Standard specifies standard materials, equipment and processing methods for evaluating carbon black in styrene-butadiene rubbers (SBR).

NOTE 1 Variations in equipment and testing procedure permitted in this International Standard can lead to discrepant results. Therefore, carbon black is preferably compared to a reference carbon black tested under the same conditions.

It is preferable to compare a reference carbon black with use under test owing to permitted variations in equipment and procedure.
