ASTM D 7854 - 16 Standard Test Method for Carbon Black-Void Volume at Mean Pressure

Current edition approved Jan. 1, 2016. Published February 2016. Originally approved in 2013. Last previous edition approved in 2015 as D7854 – 15. — 5 p.
This test method covers a procedure to measure a carbon black structure property known as Void Volume at 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.
