1.1 This test method covers a procedure to measure a carbon black structure property known as Void Volume. Compressed void volumes are obtained by measuring the compressed volume of a weighed sample as a function of applied pressure in a cylindrical chamber by a movable piston with a displacement transducer on the piston mechanism. A profile of void volume as a function of applied pressure provides a means to assess carbon black structure at varying levels of density and aggregate reduction.
1.2 Void volume is an important carbon black structure property that relates to the compounded physical properties for carbon black-filled elastomers including viscosity, modulus, and die swell.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 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.
