ASTM International Committee D03 on Gaseous Fuels invites all interested parties to participate in their standards developing activities. Proposed new standards currently being developed by subcommittees within D03 include ASTM WK24874, Test Method for the Determination of Moisture Vapor Concentration in Natural Gas and by Tunable Diode Laser Spectroscopy (TDLAS), and ASTM WK24875 , Practice for…, Tunable Diode Laser Spectroscopy, The proposed new standard, ASTM WK24874 , is being developed at the request of several gas companies that use TDLAS analyzers for the measurement of moisture in natural gas. While TDLAS has become a popular type of gas analysis, no specific standard currently exists for its use. ASTM WK24874 is under the jurisdiction of Subcommittee D03.12 on On-Line/At-Line Analysis of Gaseous Fuels. According…, Siloxanes, While biofuel from landfills and sewage digestion has been used as fuel for local gas turbine engines, it is necessary to hold the content of siloxanes within the fuel down to 50 parts per billion. Siloxanes that can coat the turbine under working conditions are converted to an abrasive silicone dioxide coating that greatly reduces the lifetime of the engine. ASTM WK24875 is currently being…

A revision to an important ASTM nanotechnology standard incorporates a large-scale interlaboratory study that took place in 2008. The revised standard, ASTM E2490 , Guide for Measurement of Particle Size Distribution of Nanomaterials in Suspension by Photon Correlation Spectroscopy (PCS), is under the jurisdiction of Subcommittee E56.02 on Characterization: Physical, Chemical and Toxicological…

Sulfur compounds are known for their smell, but odor isn’t the only issue sulfur compounds create, at least when found in various kinds of gas. Too much sulfur in gaseous fuels, such as natural gas, petroleum gases and biogases, can be corrosive to equipment, result in regulatory issues, and can inhibit or destroy catalysts used in gas processing and utilization equipment. However, sulfur gases…

The battle against cancer is being fought on many fronts. Among the most cutting-edge research efforts are attempts to engineer nanotechnology-based therapies. To aid in this endeavor, the Nanotechnology Characterization Laboratory, part of the National Cancer Institute’s Alliance for Nanotechnology in Cancer and the National Cancer Institute at Frederick, has developed methods for nanoparticle…, E2524, , Test Method for Analysis of Hemolytic Properties of Nanoparticles, -E2524 is a protocol for examining the destruction of red blood cells (hemolysis) that can lead to anemia, jaundice and other issues. All intravenously administered drugs must be examined to determine potential for hemolysis. • , E2525, , Test Method for Evaluation of the Effect of Nanoparticulate Materials on the Formation of Mouse Granulocyte-Macrophage Colonies, -E2525 describes a method for evaluating nanoparticle stimulation or inhibition of the maturation of certain bone marrow cells (macrophages). A common side effect of anti-cancer drugs is inhibition of this process, and bone marrow cells may be particularly sensitive to nano-scale material. • , E2526, , Test Method for Evaluation of Cytotoxicity of Nanoparticulate Materials on Porcine Kidney Cells and Human Hepatocarcinoma Cells, -Because studies have indicated that many nanoparticles are cleared from the body through the kidney or liver, these organs are good choices for target organ toxicity evaluation. E2526 presents a method for evaluation of nanomaterial toxicity by examining effects on kidney and cancerous liver cells. Martin Fritts is senior principal scientist at the Nanotechnology Characterization Laboratory and…

Since 1998, when ASTM International Committee F05 on Business Imaging Products first approved standard F 1856 , Practice for Determining Toner Usage for Printer Cartridges, there has been a rapid increase in the use of color in office printing. In order to address this important change, Subcommittee F05.04 on Electrostatic Imaging Products has developed F 2632 , Practice for Determining the Toner…

ASTM International Committee E56 on Nanotechnology has approved its first standard, E 2456 , Terminology for Nanotechnology. The new standard is under the jurisdiction of Subcommittee E56.01 on Terminology and Nomenclature. Because of the great need for a terminology document that is globally recognized and because of the cooperation of several organizations in making the document a reality,…

The ability to determine the number of pages an ink jet printer cartridge will print in its lifetime is essential for anyone who manufactures or remanufactures them. A new ASTM International standard, F 2555 , Practice for Determining Page Yield of Ink Jet Printer Cartridges — Continuous Printing Method, has been developed to aid in this endeavor. Practice F 2555 is under the jurisdiction of…
