A new ASTM International standard, adopted from an American Concrete Institute test method, will be used to help ensure the safety of construction projects. ASTM C1741 , Test Method for Bleed Stability of Cementitious Post-Tensioning Tendon Grout, is under the jurisdiction of Subcommittee C09.41 on Hydraulic Cement Grouts , part of ASTM International Committee C09 on Concrete and Concrete…

Piston ring/liner interface can contribute as much as half the total friction loss in internal combustion engines, with the resulting wear leading to reduced energy efficiency and raised emissions. A new ASTM International standard provides a method to more accurately measure small amounts of wear on curved piston ring segments and their counterfaces after lubricated bench-scale testing. “Coupled…

New ASTM Vitrinite Reflectance Standard Will Aid in Prediction of Undiscovered Hydrocarbon ResourcesA new ASTM International standard for measuring the reflectance of vitrinite in sedimentary rocks will help improve predictions of the location, quantity and quality of undiscovered hydrocarbon resources. ASTM D7708 , Test Method for Microscopical Determination of the Reflectance of Vitrinite Dispersed in Sedimentary Rocks, was developed by Subcommittee D05.28 on Petrographic Analysis of Coal and…, ASTM Committee D05 Next Meeting:, Oct. 30-Nov. 2, 2011, October Committee Week, Tampa, Fla., Technical Contact:, Paul C. Hackley, U.S. Geological Survey, Reston, Va., Phone: 703-648-6458; phackley@usgs.gov, 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 #8881

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. Light, Evans Cooling Systems Inc., Sharon, Conn., Phone: 860-435-2418; jtlight@comcast.net ; (D15.25) Edward Eaton Sr., Amalgatech, Phoenix, Ariz., Phone: 602-252-0280; edeaton@amalgatech.com ; (D15.30) John Panasewicz, Clear Choice Antifreeze, Henderson, Colo., Phone: 303-227-9900; johnp@clearchoiceantifreeze.com, ASTM Staff Contact:, Joe Koury, Phone: 610-832-9804; jkoury@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8837

Natural gas from unconventional sources such as coal beds has become a common target of exploration. Now, a new ASTM standard is the first to describe a method for determining the gas content of coal from such sources by desorption, using samples obtained by surface drilling. ASTM D7569 , Practice for Determination of Gas Content of Coal - Direct Desorption Method, was developed by Subcommittee…, ASTM Committee D05 Next Meeting:, May 15-18, 2011, May Committee Week, Anaheim, Calif., Technical Contact:, Peter Warwick, U.S. Geological Survey, Reston, Va., Phone: 703-648-6469; pwarwick@usgs.gov, 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 #8749

ASTM Committee G02 on Wear and Erosion is including a field trip in the plans for its Dec. 8-9 meeting in Jacksonville, Fla. Committee members will be visiting the Tribology Laboratory in the mechanical engineering department at the University of Florida in Gainesville. The Tribology Laboratory is actively involved in a wide variety of tribological research and tribology education projects. The…

A new ASTM standard will be useful to slide and engine companies, as well as makers of bushing materials, in studies that involve the measurement of system friction forces. The new standard, ASTM G203 , Guide for Determining Friction Energy Dissipation in Reciprocating Tribosystems, was developed by Subcommittee G02.50 on Friction, part of ASTM International Committee G02 on Wear and Erosion.…

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…

Moisture, volatile matter and ash are three of the primary parameters used for assessing the quality of coal. A new ASTM standard that covers the use of a macro thermogravimetric analyzer for the determination of moisture, volatile matter and ash in analysis samples of coal and coke has recently been approved by ASTM International Committee D05 on Coal and Coke. ASTM D7582 , Test Methods for…, ASTM Committee D05 Next Meeting:, May 16-19, May committee week, St. Louis, Mo., Technical Contact:, John T. Riley, Ph.D., Western Kentucky University, Bowling Green, Ky., Phone: 270-842-2757; brgrileys@insightbb.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 #8 508/Feb2010

Measuring the reflectance of vitrinite dispersed in sedimentary rocks is one of the most commonly used tools for determining thermal maturity in hydrocarbon exploration, basin modeling and other geological applications. Despite this, there currently is not a consensus standard for making these measurements. ASTM International Committee D05 on Coal and Coke is developing a proposed standard to…
