While standards for outdoor calibration techniques for solar radiometers exist, there are currently no general standards that deal with issues of indoor calibration transfers between radiometers of different design. A proposed new ASTM standard, ASTM WK27263, Test Method for Indoor Transfer of Calibration from Reference to Field Pyranometers, will address in detail issues associated with…

Regulatory agencies may soon require buffer zones around sprayed farm fields. A proposed ASTM International standard will be used to measure the drift reduction performance of tank mix adjuvants designed to reduce spray drift during the application of pesticides. Farmers can decrease the size of these buffer zones by using these adjuvants. ASTM WK27419 , Test Method for Characterization of…

The U.S. Environmental Protection Agency registered 282 copper alloys as antimicrobial materials with public health claims in February 2008. Now, test methods developed in discussions between the EPA and the Copper Development Association during the registration process are being developed as proposed ASTM International standards. Subcommittee E35.15 on Antimicrobial Agents, part of ASTM…, ASTM Committee E35 Next Meeting:, April 19-22, April committee week, St. Louis, Mo., Technical Contact:, James H. Michel, Copper Development Association Inc., New York, N.Y., Phone: 212-251-7210; jmichel@cda.copper.org, ASTM Staff Contact:, Jennifer Rodgers, Phone: 610-832-9694; jrodgers@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8 508/Feb2010

Outbreaks of the H1N1 influenza this year have increased the public’s awareness and use of leave-on hand antiseptics, popularly known as hand sanitizers. ASTM International Committee E35 on Pesticides and Alternative Control Agents is now developing a proposed new standard that will measure the antibacterial activity of hand sanitizers on people’s hands. ASTM WK23789 , Test Method for Evaluation…

Biofilm, which is defined as microorganisms living in a self-organized cooperative community, is still under the radar for many industry, medical, professional and regulatory agencies. A newly approved ASTM International standard is the latest in a series of biofilm standards being developed by Committee E35 on Pesticides and Alternative Control Agents. The new standard, E2647 , Test Method for…

Explorations into alternative forms of energy have increased interest in standards for solar energy applications. ASTM International Committee G03 on Weathering and Durability has recently approved a new standard in this area, G197 , Table for Reference Solar Spectral Distributions: Direct and Diffuse on 20° Tilted and Vertical Surfaces. ASTM G197 was developed by Subcommittee G03.09 on…

ASTM International Committee E35 on Pesticides and Alternative Control Agents has begun work on the latest in a series of standards on biofilm. The proposed new standard, WK17813 , Test Method for Quantification of a, Pseudomonas aeruginosa, Biofilm Grown with Low Shear and Continuous Flow Using a Drip Flow Biofilm Reactor, is being developed by Subcommittee E35.15 on Antimicrobial Agents. According to Darla M. Goeres, senior research engineer, Center for Biofilm Engineering, and E35 member, biofilm is defined as microorganisms living in a self-organized cooperative community. These communities, which are embedded in slime and can be…, Pseudomonas aeruginosa, Biofilm Grown with High Shear and Continuous Flow Using CDC Biofilm Reactor; and E2196 , Test Method for Quantification of a, Pseudomonas aeruginosa, Biofilm Grown with Shear and Continuous Flow Using a Rotating Disk Reactor) is that biofilm is grown under low fluid shear close to the air/liquid interface and that the drip flow reactor is a plug flow reactor system, resulting in biofilm that is visible to the naked eye and smooth and slimy in appearance. Biofilm generated in a drip flow reactor could represent those found in a wide spectrum of…
