    Significance and Use

    5.1 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:

    1. Scope

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

     

    Sections

      Test Method A—Visual Inspection

    3 – 11

      Test Method B—Agglomerate Count

    12 – 22

      Test Method C—Microroughness Measurement

     

        with Profilometer

    23 – 33

      Test Method D—Microroughness Measurement with IFM

    34 – 42


    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.
