ASTM International’s pesticides formulation subcommittee is looking for more people to help develop a standard for spray-tank cleaners, which are used by the agriculture industry. Different kinds of pesticide mixtures are increasingly sprayed from tanks onto various kinds of crops, according to ASTM member Todd O’Connell, chairman of the pesticides formulation subcommittee. When a new mixture is…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Brian Milewski, tel +1.610.832.9619; bmilewski@astm.org Release #10884

ASTM International’s committee on pesticides, antimicrobials, and alternative control agents (E35) is developing a standard (WK64329) for wipes that detect , Bacillus anthracis , spores, a biological threat agent that can infect people with anthrax. ASTM International member Laura Rose, a microbiologist at the U.S. Centers for Disease Control and Prevention, notes that , Bacillus anthracis , is a “biosafety level 3 pathogen” that infects some livestock naturally but can cause severe illness in humans. The proposed standard is a laboratory test method for processing wipes or sponges used to collect samples from surfaces that have potentially been contaminated with the spores. “ The method specifies how best to get the spores off the sponges and into a liquid, which can then be…, B. anthracis , contamination event, and assist in developing methods to quantify and detect other microorganisms in the environment. She notes that researchers interested in evaluating the efficiency and sensitivity of various sampling materials or tools could find the proposed standard useful. This effort directly relates to the United Nations Sustainable Development Goal #3 on good health and well-being. …, Bacillus anthracis, , according to Rose.

A new ASTM International test method aims to help improve aircraft decontamination processes. The new standard (E3092 ) was developed by ASTM International’s committee on pesticides, antimicrobials, and alternative control agents ( E35 ). The test method describes how to measure inactivation of, Bacillus, spores using hot, humid air., Bacillus, spores can come from insecticidal applications, natural environmental contamination or contamination from a terrorist attack., Bacillus, spores are also used as biological indicators to measure the success of decontamination processes. “The technology and the tests were developed for aircraft decontamination,” says ASTM International member Alice Young. “However, the standard has broad application to sensitive material decontamination not related to aircraft as well.” Young notes that the standard could potentially be modified…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Brian Milewski, tel +1.610.832.9619; bmilewski@astm.org Release #10599
