ASTM International Committee D05 on Coal and Coke is seeking participation in the development of a proposed new standard, WK9165, Test Methods for Loss on Ignition of Solid Combustion Residues. According to John Riley, a recently retired chemistry professor at Western Kentucky University, the question of how loss on ignition testing is done is an issue that a task group he chairs began looking at…

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…

In the past, the only measurement used to determine whether sealants could endure a great deal of foot traffic was hardness. Because research presented at symposia and from the field has shown that other factors need to be considered in the design and use of traffic sealants, ASTM International Committee C24 on Building Seals and Sealants has a new proposed standard that encompasses a wider range…
