ASTM D3849 is the only recognized standard method for the digital measurement of carbon black particle size statistics via transmission electron microscopy (TEM). The method makes use of fractal geometry to derive particle size statistics for both aggregates and primary particles using only the measured values of aggregate perimeter and area. Despite the sophistication of ASTM D3849, there has been disagreement in the industry regarding its utility and inter-laboratory reproducibility especially with regards to smaller grades of carbon blacks. As a leader in third-party testing, Smithers has recently developed a methodology based on ASTM D3849 that seeks to address these issues and improve identification of recovered carbon black obtained from mixed rubber samples.

Carbon black is one of the most important raw materials in the rubber industry. It is a form of elemental carbon produced through the incomplete combustion of hydrocarbon oils under controlled conditions. When mixed with rubber, carbon black acts as a filler to reduce cost and reinforce the bulk compound. Carbon black is used to tailor rubber performance properties such as tensile strength, abrasion resistance, and conductivity.
