ASTM International Committee D05 on Coal and Coke is currently seeking participation in the development of a proposed new standard, WK10700 , Test Method for Total Moisture in Coal Reduced to 2.36 mm (No. 8 Sieve) Topsize Through Determination of Air-Drying Loss by Microwave Oven. The proposed new standard is under the jurisdiction of Subcommittee D05.21 on Methods of Analysis. While air-drying…

ASTM International Committee C26 on Nuclear Fuel Cycle has approved two new standards, both under the jurisdiction of Subcommittee C26.05 on Methods of Test. All interested parties are invited to participate in the standards developing activities of Committee C26. ASTM International standards are available for purchase from Customer Service (phone: 610/832-9585; https://www.astm.org/contact )…, ASTM C 1637 , Test Method for the Determination of Impurities in Plutonium Metal: Acid Digestion and Inductively Coupled Plasma-Mass Spectroscopy (ICP-MS) Analysis, The approval of C 1637 is part of Subcommittee C26.05’s project involving the approach to keeping the analytical methodology used for determining specifications for nuclear materials up to date. This project began in 1990 when the subcommittee decided to develop separate standards from methods that were part of larger multi-methods materials specification standards. Once the new test methods…, ASTM C 1638 , Guide for the Determination of Iodine-129 in Uranium Oxide, Guide C 1638 covers the determination of iodine-129 in uranium oxide by gamma-ray spectrometry. Users may include U.S. Department of Energy sites that are dispositioning excess uranium to waste sites. Although there is no specification for the levels of I-129 in fuel, waste disposal sites may set limits due to the potential mobility of iodine in the environment. This guide may be used to ensure…

ASTM Committee D05 on Coal and Coke is currently developing a proposed new standard, WK10380, Practice for Establishing the Competence of Laboratories Using ASTM Procedures in the Sampling and Analysis of Coal and Coke. The proposed standard will specify requirements for establishing, operating and evaluating a laboratory that provides services in the areas of sample collection and preparation…

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…

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…

ASTM International Committee C24 on Building Seals and Sealants is currently working to fill a need for a weatherproofing sealant field test standard. The result, proposed standard WK7800, Guide for a Non-Destructive, Continuous, Field Test of Installed Weatherproofing Sealant, features a field test that has been used by sealant professionals for years, but has not, up to this point, been…

ASTM International Committee C24 on Building Seals and Sealants is now working on a proposed new standard, WK6920, Fatigue Resistance of Structural Silicone. The standard, which is under the jurisdiction of ASTM Subcommittee C24.20 on General Sealant Standards, is intended to serve as an enhancement to current performance requirements for structural silicones and to help users ascertain that…

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…
