ASTM International’s water committee ( D19 ) has approved a new standard that will help water producers and users identify and quantify bacteria in potable (drinking, dental, and bottled water) as well as nonpotable water (cooling towers). Heterotrophic bacteria count (HPC) determines the overall number of bacteria in a water sample, allowing water system managers and water treatment…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Brian Milewski, tel +1.610.832.9619; bmilewski@astm.org Release #11735 ###

ASTM International’s unmanned aircraft systems (UAS) committee ( F38 ) has approved a new subcommittee on infrastructure. The mission of the new subcommittee (F38.04) is to identify, evaluate, and establish best practices for the design, construction, and maintenance of UAS infrastructure. This included landing and takeoff zones, charging and refueling stations, and date communications systems. "…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Mary Mikolajewski, tel +1.610.832.9678; mmikolajewski@astm.org Release #11696 ###

Two proposed standards from ASTM International’s water committee ( D19 ) are devoted to different aspects of water quality. The first proposed standard ( WK68866 ) will provide a screening method to assess contaminants in water samples prior to a more detailed analysis. If approved, this standard will cover the determination of adsorbable organic fluorine (AOF) in waters and waste waters that can…, 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 #11643 ###

ASTM International’s unmanned aircraft systems committee ( F38 ) is developing a proposed standard that will help identify communications security principles and relevant frameworks for securing ad hoc uncrewed aircraft system communications. ASTM member Drew Van Duren says that the proposed standard ( WK84631 ) will identify and describe a tailorable approach to securing aircraft-to-anything (…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Mary Mikolajewski, tel +1.610.832.9678; mmikolajewski@astm.org Release #11625 ###

A new ASTM International standard supports the design of civil vertiports and vertistops. The standard ( F3423 ) is the result of a five-year effort by ASTM’s unmanned aircraft systems committee ( F38 ). A vertiport is a section of land, water, or structure intended for either manned or unmanned vertical takeoff and landing of aircraft, along with the associated buildings and facilities. A…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Mary Mikolajewski, tel +1.610.832.9678; mmikolajewski@astm.org Release #11524 ###

ASTM’s water committee ( D19 ) has approved a new standard that will help ensure compliance with drinking water quality requirements, minimize environmental impact, and protect public health. The new standard, published as D8431 , is based on the HORIBA A-TEEM spectroscopy technique. It will be used at treatment plants for drinking water as a first line of defense for detecting petroleum product…, 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 #11506 ###,

A new ASTM International standard provides a test method for finding low concentrations of nitrosamines, a suspected type of carcinogen, in water. The standard ( D8456 ) was developed by ASTM’s water committee ( D19 ). Nitrosamines exist in low concentrations in water, foods, vegetables, and dairy products. According to ASTM International member William Lipps, this standard presents a relatively…, 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 #11486 ###

A new ASTM International standard ( F3548 ) will be used to satisfy requirements that are expected to be common for traffic management of uncrewed aircraft systems (UAS), commonly referred to as drones. The flight operations subcommittee of ASTM’s unmanned aircraft committee ( F38 ) developed the new standard on UAS traffic management (UTM) with input garnered across multiple continents and a…

ASTM International’s water committee ( D19 ) is working to reinstate a standard used in the desalination (the removal of salts and other materials) of seawater. The proposed standard ( WK80178 ) will replace a discontinued standard using the Stiff and Davis stability index for reverse osmosis. The Stiff and Davis index is an easy way to calculate calcium carbonate scaling tendencies in brines.…
