ASTM WK39281

    Work Item: ASTM WK39281 - New Test Method for Standard Test Method for Carbon Black-Void Volume at Geometric Mean Pressure

    (What is a Work Item?)

    Developed by Subcommittee: D24.11 | Committee D24 | Contact Staff Manager

    1. Scope

    1.1This test method covers a procedure to measure a carbon black structure property known as Void Volume at geometric mean pressure. Compressed void volumes are obtained by measuring the compressed volume of a weighed sample in a cylindrical chamber as a function of pressure exerted by a movable piston. A profile of void volume as a function of pressure provides a means to assess carbon black structure at varying levels of density and aggregate reduction.

    To enable the carbon black and rubber industries to utilize common void volume measurement parameters to measure carbon black primary structure. Typical users are quality laboratories.


    13.1Structure, apparent volume; theoretical volume; void volume, geometric mean pressure

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