While there are many commercially available stormwater treatment products currently on the market, there is no universal testing standard that would allow the performance of these products to be accurately compared. A proposed new ASTM International standard will fill this need, providing a testing method for stormwater treatment products that use filtration as a primary treatment process. ASTM…

A watertight septic system ensures its integrity, and demonstrating that integrity is important because such systems have over time become more complex, expensive and critical to both system owners and to the environment. A new ASTM International standard fills a need for an in-field installation test for septic systems. The new standard, ASTM C1719 , Test Method for Installed Precast Concrete…, ASTM Committee C27 Next Meeting:, Dec. 6-7, 2011, December Committee Week, Tampa, Fla., Technical Contact:, Michael R. Miller, Press-Seal Gasket Corp., Fort Wayne, Ind., Phone: 260-918-1626; mmiler@press-seal.com, ASTM Staff Contact:, Joseph Hugo, Phone: 610-832-9740; jhugo@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #9008

ASTM International Committee E56 on Nanotechnology has created a new subcommittee, E56.06 on Nano-Enabled Consumer Products. The scope of E56.06 is to develop scientifically credible standards for identification, evaluation and assessment of engineered nanomaterials in consumer products. Members of E56.06 will develop standards for determining the presence of engineered nanomaterials in consumer…, ASTM Committee E56 Next Meeting:, Nov 15-16, November Committee Week, San Antonio, Texas, Technical Contact:, (Chairman, E56) Debbie Kaiser, National Institute of Standards and Technology, Gaithersburg, Md., Phone: 301-975-6759; debra.kaiser@nist.gov ; (Subcommittee E56.06) Aleks Stefaniak, National Institute for Occupational Safety and Health, Morgantown, W.Va., Phone: 304-285-6302; boq9@cdc.gov, ASTM Staff Contact:, Timothy Brooke, Phone: 610-832-9729; tbrooke@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8698/Sept2010

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…
