A newly approved standard, ASTM D7338 , Guide for the Assessment of Fungal Growth in Buildings, has been developed to provide a go-to reference for anyone testing for mold in buildings. The new standard was developed by Subcommittee D22.08 on Sampling and Analysis of Mold, part of ASTM International Committee D22 on Air Quality. “The lack of consensus standards in the fungal sampling and analysis…, ASTM Committee D22 Next Meeting:, April 10-13, April Committee Week, Anaheim, Calif., Technical Contact:, Lisa Rogers, Mycometer, Inc., Tampa, Fla., Phone: 813-831-6511; lrogers@mycometer.com, ASTM Staff Contact:, David Bradley, Phone: 610-832-9681; dbradley@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8788

An effort currently under way by the U.S. Federal Highway Administration to set national standards for minimum maintained retroreflectivity levels for pavement markings has illustrated the need for a practical protocol to measure such levels. In response to this need, ASTM International Committee D04 on Road and Paving has developed ASTM D7585/D7585M , Practice for Evaluating Retroreflective…

Air permits from regulatory agencies, such as the U.S. Environmental Protection Agency (USEPA), often require the measurement of a plume's opacity as the plume is emitted from a stationary point source (for example, smokestacks) in the outdoor ambient environment. While such opacity is often visually measured by human observers as “certified smoke readers,” an opacity measurement method using…

The need for a standard test method that would allow the determination of the complex shear modulus of bituminous mixtures using relatively inexpensive laboratory equipment has led to the development of a new ASTM International standard, ASTM D7552 , Test Method for Determining the Complex Shear Modulus (G*) of Bituminous Mixtures Using Dynamic Shear Rheometer. According to Gerald Reinke,…, ASTM Committee D04 Next Meeting:, June 8-10, June committee week, St. Louis, Mo. Technical Contact: Gerald Reinke, MTE Services Inc., Phone: 608-779-6304; greinke@mathy.com ASTM Staff Contact: Daniel Smith, Phone: 610-832-9727; dsmith@astm.org ASTM PR Contact: Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8457/Jan2010

More frequent worldwide use of asphalt-rubber binders in road building has increased the need for rotational viscotesters, which are used to ensure proper quality control and assurance. While an appropriate standard for viscotesters does not currently exist, a proposed new ASTM standard will answer this need. The proposed standard, WK25108 , Test Method for Measurement of Apparent Viscosity of…

Test for Solubility of Asphalt Materials in n-Propyl Bromide A new ASTM International standard on solubility of asphalt will provide an alternative for a solvent that has been banned as an ozone depleter by the Kyoto Protocol, an international environmental treaty with the goal of stabilizing greenhouse gas concentrations that may help minimize global warming. The new standard, ASTM D7553 , Test…
