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 ,…

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.

A proposed new ASTM standard will assist in establishing tests for fretting fatigue, an issue at attachments and joints in a variety of mechanical, aeronautical and biomedical engineering systems and devices. WK24298 , Guide for Fretting Fatigue Testing, is being developed by Subcommittee E08.05 on Cyclic Deformation and Fatigue Crack Formation, part of ASTM International Committee E08 on Fatigue…, ASTM Committee E08 Next Meeting:, May 17-20, 2010, May Committee Week, St. Louis, Mo., Technical Contact:, Richard W.

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…

Data produced from the use of a proposed new ASTM International standard will be employed in the design of new, more efficient aircraft engines as well as for piping, steam and gas turbines used in power generation. The proposed new standard, WK21984 , Test Method for Creep-Fatigue Crack Growth Rate Testing, is being developed by Subcommittee E08.06 on Crack Growth Behavior, part of ASTM…

No industry standard currently exists that addresses the vacuum sealing requirements of knife-edged flanges for high vacuum applications. Existing international standards focus on interchangeability of the hardware, but do not address the reliability of the seal. ASTM International Committee E42 on Surface Analysis is now working on a proposed standard on the subject, WK21206 , Specification…

A 2002 workshop on galling wear held by ASTM International Committee G02 on Wear and Erosion provided the impetus for the development of a new standard, ASTM G196 , Test Method for Galling Resistance of Material Couples. The new standard is under the jurisdiction of Subcommittee G02.40 on Non-Abrasive Wear. According to Scott Hummel, Ph.D., associate professor, head of the department of…

Many factors, such as traffic, drainage, structure and climatic variations, impact the field performance of asphalt concrete. However, asphalt concrete performance has been more accurately predicted when laboratory material properties are known, so ASTM International Committee D04 on Road and Paving Materials has approved a new standard, ASTM D7460 , Test Method for Determining Fatigue Failure of…
