Sampling is a difficult but essential part of the coal production process. ASTM International Committee D05 on Coal and Coke hopes to streamline that process with the publication of new standard D 7256/D 7256M, Practice for Mechanical Collection and Within-System Preparation of a Gross Sample of Coal from Moving Streams. Practice D 7256/D 7256M is under the jurisdiction of Subcommittee D05.23 on…

Most of the coal burned in the United States contains only trace amounts of chloride and fluoride. However, due to the increasing regulation of these compounds for clean air initiatives, being able to measure even small amounts of chloride and fluoride in coal has taken on a greater importance than ever. Recognizing this, ASTM International Committee D05 on Coal and Coke has begun to develop a…

Natural gas from unconventional sources, such as from coal beds (coal bed methane), has become a common target for exploration in recent years. Coal gas demand continues to grow and is expected to provide about 10 percent of U.S. production in the future. However, there are no standards available that describe procedures used to determine the gas content of North American coal and the most…
