Many structures, such as aircraft or other lightweight vehicles, are made from thin-ductile structural materials that exhibit low crack-front constraint, which allows for extensive plastic yielding of the material around a crack front. However, many current standards, such as E 399, Test Method for Linear-Elastic Plane-Strain Fracture Toughness K Ic of Metallic Materials, or E 1820, Test Method…

Proposed New ASTM International Homeland Security Standard to Provide Preparedness Plans for SchoolsThe mass murder at Columbine High School in Littleton, Colo., in 1999 brought the subject of school security into the U.S. national spotlight and subsequent events, including other school-related incidents and the attacks of Sept. 11, 2001, have kept it there. A proposed new ASTM International standard will help schools and school districts prepare for and mitigate against both large-scale…

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…

Robots have a long and storied history in science fiction, but the rapid advance of technology has placed robotics very much within the realm of science fact. A new ASTM International initiative has now been launched that will investigate the role of robots in search and rescue operations. ASTM International has recently been selected by the U.S. Department of Homeland Security (DHS) 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…

A longtime need for better standardization and testing of sporicides has led to the approval of a new ASTM International standard, E 2414, Test Method for Quantitative Sporicidal Three-Step Method (TSM) to Determine Sporicidal Efficacy of Liquids and Vapor or Gases on Contaminated Carrier Surfaces. The newly approved test method, under the jurisdiction of Subcommittee E54.03 on Decontamination,…
