The purpose of a laboratory roadwheel test is to realistically evaluate tires for specific road conditions. To facilitate such tests, ASTM International Committee F09 on Tires has developed a practice to provide an industry standard for commercial radial truck-bus tire laboratory temperature algorithms. The algorithms equilibrate with flat surface (highway) operating temperatures to determine…

A rim slip performance test for tires that has been done at the Nevada Automotive Test Center for more than 20 years has now become an ASTM International standard. ASTM F2803 , Test Method for Evaluating Rim Slip Performance of Tires and Wheels, was developed by Subcommittee F09.20 on Vehicular Testing, part of ASTM International Committee F09 on Tires. Rim slip occurs when tire and wheel…, ASTM Committee F09 Next Meeting:, April 21-22, April committee week, St. Louis, Mo., Technical Contact:, Jason Whiteley, Nevada Automotive Test Center, Silver Springs, Nev., Phone: 775-629-2000, jwhiteley@natc-ht.com, ASTM Staff Contact:, Rick Lake, Phone: 610-832-9689; rlake@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8494/Feb2010

Engineers and researchers who have specialized Charpy testing needs will be the primary users of two new standards recently approved by ASTM International Committee E28 on Mechanical Testing. The new standards, E2248 , Test Method for Impact Testing of Miniaturized Charpy V-Notch Specimens, and E2298 , Test Method for Instrumented Impact Testing of Metallic Materials, were developed by…

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…

Working toward a standard practice for torque calibration that would reduce laboratory inconsistencies and uncertainties has led to the approval of a new ASTM International standard, E2428 , Practice for Calibration of Torque-Measuring Instruments for Verifying the Torque Indication of Torque Testing Materials. The new standard was developed by Subcommittee E28.01 on Calibration of Mechanical…
