Two new standards have recently been approved by ASTM International Committee D04 on Road and Paving Materials. The standards, both of which are under the jurisdiction of Subcommittee D04.26 on Fundamental/Mechanistic Tests, are D 6931 , Test Method for Indirect Tensile (IDT) Strength of Bituminous Mixtures, and D 7312 , Test Method for Determining the Permanent Shear Strain and Complex Shear…, ASTM D 6931, Test Method for Indirect Tensile (IDT) Strength of Bituminous Mixtures, The withdrawal of D 4123 , Test Method for Indirect Tension Test for Resilient Modulus of Bituminous Mixtures, led to the development of D 6931 , since D 4123 contained a description of an indirect tensile strength test that was referred to in several other standards. It was decided to develop this test into a completely separate standard, D 6931, to stand on its own merit as a method that…, ASTM D 7312, Test Method for Determining the Permanent Shear Strain and Complex Shear Modulus of Asphalt Mixtures Using the Superpave Shear Tester (SST), According to Rebecca McDaniel, technical director, North Central Superpave Center, and leader of the D 7312 task group, Superpave is a system for designing asphalt mixtures to ensure that the right asphalt binder and aggregate structure is used for the traffic and climate where it will be placed on the road. To facilitate the implementation of Superpave, the Federal Highway Administration…

ASTM International Committee C26 on Nuclear Fuel Cycle has recently published a new standard and has begun the development of a proposed new standard. Subcommittee C26.14 on Remote Systems is responsible for the newly approved standard, C 1661 , Guide for Viewing Systems for Remotely Operated Facilities, while Subcommittee C26.02 on Fuel and Fertile Material Specifications is currently at work on…, C 1661, Guide for Viewing Systems for Remotely Operated Facilities, A new ASTM International standard establishes minimum requirements for viewing systems for remotely operated facilities, including hot cells, used for the processing and handling of nuclear and radioactive materials. The standard, C 1661 , Guide for Viewing Systems for Remotely Operated Facilities, was developed by Subcommittee C26.14 on Remote Systems, which is part of ASTM International…, WK14330, Nuclear Fuel Pellet Physical Integrity Limits: Chips, Cracks, Defects, The quality of fuel pellets is currently an important topic being studied throughout the nuclear industry, with study groups such as the Electric Power Research Institute and Institute of Nuclear Power Operations examining the effect of pellet quality on the performance of nuclear fuel. ASTM International Committee C26 on Nuclear Fuel Cycle is addressing the topic of fuel pellets with a proposed…

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…
