Significance and Use

Visual dispersion ratings correlate with certain important physical properties of the compound. A rating of 5 indicates a state of dispersion developing near maximum properties, while a rating of 1 would indicate a state of dispersion developing considerably depressed properties. Normally, the visual dispersion ratings indicate the following levels of compound quality:

Visual Dispersion RatingClassification
4 to 5High
3 to 4Intermediate
2 to 3Low
1 to 2Very low

Scope

1.1 These test methods cover the degree of dispersion of carbon black in rubber. Three test methods are described as follows:

Sections
Test Method AVisual Inspection 3-11
Test Method BAgglomerate Count12-23
Test Method CMicroroughness Measurement
with Profilometer24-34
Test Method DMicroroughness Measurement with IFM35-43

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.
