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 ,…

Among the proposed new standards that ASTM Committee E05 on Fire Standards is currently working on are two that cover aspects of fire exposure. Committee E05 is meeting in Atlanta in December and welcomes participation in its standards developing activities., Roof Field Vent Response, Embers from wildfires can travel through the air up to four miles away from the fire source, particularly in areas where wind is often prevalent during fire season. These embers can then enter structures through ventilation systems and other openings in a building envelope, resulting in fires being ignited from within a structure. A proposed new ASTM standard will cover a test for the resistance…, Fire Response, Subcommittee E05.14 is also working on ASTM WK25760 , Guide for Quantification of Fire Exposures. The proposed standard will cover fire exposure metrics that will be used in the development of fire test methods. According to Jon Traw, president, Traw Associates Consulting, and chairman of Task Group E05.14.08, the proposed standard will serve as a critical tool in the development of appropriate…, ASTM Committee E05 Next Meeting:, Dec. 6-9, ASTM Committee Week, Atlanta, Ga., Technical Contacts:, (WK23700) Gregory Daniels, O’Hagin’s Inc., Rohnert Park, Calif., Phone: 707-303-3660; gdaniels@ohaginvent.com ; (WK25760) Jon Traw, Traw Associates Consulting, Whittier, Calif., Phone: 562-789-7583; trawassoc@yahoo.com, ASTM Staff Contact:, Thomas O’Toole, Phone: 610-832-9739; totoole@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8423/Dec2009
