WASHINGTON, D.C. – New regulations set forth by the U.S. Environmental Protection Agency to mandate greenhouse gas reporting in the U.S. carbon black industry have led to the development of a new ASTM International standard, ASTM D 7662, Test Method for Carbon Content in Carbon Black Feedstock Oils.

Measuring the total carbon content of feedstock oils is an important step in calculating carbon dioxide emissions, estimating the yield of a process or assessing product quality. ASTM D 7662 is applicable to most commercial feedstock oils used to produce carbon black products in a furnace or thermal process.
