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

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 ,…

Rapid hardening hydraulic cements are used in a variety of applications in which reduced cementitious contents are desired or early service is needed. Included among these applications are paving, construction, stucco, mortar and block. A newly approved ASTM International standard covering these cements, ASTM C1600/C1600M , Specification for Rapid Hardening Hydraulic Cement, has been developed by…, Type URH, —ultra rapid hardening, for use where ultra high early strength is desired;, Type VRH, —very rapid hardening, for use where very high early strength is desired;, Type MRH, —medium rapid hardening, for use where mid-range rapid hardening, high early strength is desired; and, Type GRH, —general rapid hardening, for use when the higher strength properties of Type VRH or a Type MRH cement is not required. “ASTM C1600 lists minimum requirements for compressive strength, setting time, shrinkage and soundness (autoclave expansion),” says Hicks. “Optional specifications for sulfate expansion, alkali silicate reactions with aggregates, heat of hydration and expansion in water are also…

The presence of lead in toys and other consumer products continues to make headlines. The Consumer Product Safety Improvement Act, a United States law enacted in August 2008, addresses the lead issue and makes provisions for the use of X-ray spectrometry in testing for lead content. To aid the toy and consumer products industries in using X-ray spectrometry for lead detection and meet the…
