ASTM WK30885

    New Test Method for Rubber Property - Macro-Dispersion of Fillers in Compounds

    (What is a Work Item?)

    Developed by Subcommittee: D11.12 | Committee D11 | Contact Staff Manager


    1. Scope

    This test method covers a procedure to measure the macro-dispersion of fillers in a rubber matrix by quantifying the surface roughness of a freshly cut specimen using an optical microscope in reflection mode.


    Carbon Black; silica; rubber compounds; incorporation; dispersion


    Optical methods of measuring dispersion of fillers in rubber compounds provide a rapid, objective measure that is practical for routine laboratory testing. Both unvulcanized and vulcanized rubber compounds may be evaluated using this test method.

    The title and scope are in draft form and are under development within this ASTM Committee.
