ASTM International Committee D15 on Engine Coolants has formed three new subcommittees: Subcommittees D15.22 on Non-Aqueous Coolants ; D15.25 on Diesel Exhaust Fluid ; and D15.30 on Industrial Heat Transfer Fluids . All interested parties are invited to join in the standards developing activities of these new subcommittees., D15.22, Non-Aqueous Coolants, While there has been an increased interest in non-aqueous coolants industry, there are no current ASTM standards in this area. D15.22 will begin to develop such standards. “The envisioned standards for non-aqueous coolants would be performance standards, rather than ingredient standards, to allow for formulations that are not currently proprietary,” says Jonathan T. Light, chief engineer, Evans…, D15.25, Diesel Exhaust Fluid, Diesel exhaust fluid, often referred to as DEF, is required by many diesel engine-powered vehicles delivered after January 2010. More recent environmental standards issued by the U.S. Environmental Protection Agency have created more stringent emissions standards for agricultural, construction and forestry equipment. DEF is used to reduce nitrogen oxide emissions, which allows original equipment…, D15.30, Industrial Heat Transfer Fluids, Members of D15 recognized that changes in the antifreeze industry, including new manufacturing technologies, improved inhibitor chemistries and recycling technologies, would likely be adapted to the facilities industry as a natural course of innovation. Because D15 has experience developing standards that are technically similar to the facilities heat transfer industry, it was deemed appropriate…, ASTM Committee D15 Next Meeting:, May 17-18, May Committee Week, Anaheim, Calif., Technical Contact:, (D15.22) Jonathan T.

Fatigue fretting is the process of crack formation and progressive crack growth at a location in a mechanical system where two components are in contact and undergoing a vibratory loading. A new ASTM International standard provides insight on what conditions promote fretting fatigue and offers approaches to design an experiment to assess it. ASTM E2789 , Guide for Fretting Fatigue Testing, was…, ASTM Committee E08 Next Meeting:, May 16-20, May Committee Week, Anaheim, Calif., Technical Contact:, Richard W. Neu, Georgia Institute of Technology, Atlanta, Ga., Phone: 404-894-3074; rick.neu@gatech.edu ASTM Staff Contact: Jeff Adkins, Phone: 610-832-9738; jadkins@astm.org ASTM PR Contact: Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org R elease #8809

The proper selection of assessors can have a direct effect on the outcome of any sensory or consumer test. A proposed new ASTM International standard will help users determine appropriate assessors, give general guidelines for ways to select and recruit respondents, and list the benefits and drawbacks in selecting certain assessors. The proposed new standard, ASTM WK30847 , Guide for Selection of…

Product selection is an important, though sometimes neglected, part of the consumer testing process. A proposed new ASTM standard will offer guidelines to bring clarity to this process. The proposed standard, ASTM WK30844 , Guide for Sampling of Product for Evaluation, is being developed by Subcommittee E18.04 on Fundamentals of Sensory, part of ASTM International Committee E18 on Sensory…, ASTM Committee E18 Next Meeting:, April 12-14, 2011, April Committee Week, Anaheim, Calif., Technical Contact:, Julie Boutaghou, Boutaghou LLC, North Oaks, Minn., Phone: 651-788-5550; j ulieboutaghou@msn.com, ASTM Staff Contact:, Scott Orthey, Phone: 610-832-9730; sorthey@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8751

A series of proposed new standards being developed by ASTM International Committee D15 on Engine Coolants would remove technical barriers that currently prevent the cost-effective replacement of ethylene glycol with more environmentally friendly glycerin in antifreeze. The proposed standards are under the jurisdiction of Subcommittee D15.93 on Research and Long Range Planning. Natural glycerin is…

Creep-fatigue testing simulates the loading and temperature conditions experienced by turbine components of aircraft engines, nuclear reactor components and fossil power plant components during service. With increasing need for cyclic operation during peak power demands, reliable creep-fatigue test data is necessary for the life assessment of aging power plants. A new ASTM standard, ASTM E2714 ,…
