WEST CONSHOHOCKEN, Pa. (Aug. 17, 2010)—The American Society of Testing and Materials has issued a new international standard, ASTM D7633, Test Method for Carbon Black Carbon Content.
New regulations from the U.S. Environmental Protection Agency, mandating greenhouse gas reporting from the carbon black industry, necessitated the new standard, the ASTM. ASTM Subcommittee D24.66 on Environment, Health and Safety, part of ASTM International Committee D24 on Carbon Black, developed the standard.
“The total carbon content of a carbon black is a requirement for the calculation and reporting of carbon dioxide emissions,” said the preamble to ASTM D7633 on the ASTM website, www.astm.org. “It can also be used in calculations to estimate yield of the process.”
Carbon black producers and contract laboratories will be the primary users of ASTM D7633, ASTM said. The standard may be adopted into U.S. and Canadian greenhouse gas regulations, and eventually into regulations in the European Union and elsewhere, it said.
Subcommittee D24.66 has already developed test standards to measure sulfur content of carbon black and possible carbon black fugitive emissions. The subcommittee is working on a test method to measure carbon content in carbon black feedstock oils. It also has formed a task group to administer an interlaboratory study program that will be used to develop precision and bias instruments for ASTM D7633.
