The quantity of non-dispersible matter of carbon black is important in some molded or extruded products as it may relate to the surface appearance of those products. The maximum amount of non dispersible matter and the minimum size of the particles to be analyzed in each application is normally determined and agreed to between the user and the producer.

1. Scope

1.1 This test method covers the determination of non-dispersible matter after mechanical water flushing of regular untreated carbon blacks. It may not be applicable to oil-treated carbon blacks because the oil would prevent proper wetting of the black by water.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
