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.

    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.
