Standard Test Methods for Rubber—Determination of Carbon Black in Masterbatches

Importancia y uso:

4.1 The carbon black content of an unvulcanized black or oil-black SBR masterbatch may be determined by this test method if an inert (CO₂) atmosphere and a determinate (see Note 2) of known carbon black content are available.

Note 2: Determinate black masterbatch may be prepared by careful addition of exact amounts of rubber and carbon black on a mill. An alternative would be a thorough blending of a quantity of black masterbatch and determination of the carbon black by use of a previously established determinate.
