The expected discontinuance in manufacturing a standard-reference test tire will lead to changes to an ASTM International standard ( E1136 , Specification for P195/75R14 Radial Standard Reference Test Tire). Users of this specification are invited to join an ASTM task group that is working to manage this transition. The tire has been used extensively since its introduction in the late 1980s.…, ASTM Committee F09 on Tires Next Meeting:, Oct. 13-14, 2015, MAPS Air Museum, North Canton, Ohio, Media Inquiries:, Nathan Osburn, tel +1.610.832.9603; nosburn@astm.org, Technical Contact:, Angela Wolynski, Michelin North America, tel +1.864.422.4985; angela.wolynski@us.michelin.com, ASTM Staff Contact:, Julia Lively, tel +1.610.832.9681; jlively@astm.org Release #9880

A need for a scientifically based procedure to identify equivalent test severity conditions between a 1.707-m diameter laboratory roadwheel surface and a flat or highway surface for radial pneumatic light truck tires has led to the development and approval of a new ASTM International standard. The new standard, ASTM F2869 , Practice for Radial Light Truck Tires to Establish Equivalent Test…

In the Transportation Recall Enhancement, Accountability and Documentation Act, the U.S. Congress indicated the need for an aging test on light vehicle tires. Since no industry or government standard addressed this subject, ASTM Committee F09 on Tires developed ASTM F2838 , Practice for Accelerated Laboratory Aging of Radial Passenger Car and Light Truck Tire Through Load Range E for the…

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

High-speed machine tool spindles and the high-pressure turbopumps that move liquid hydrogen in the space shuttle are just two examples of the uses for hybrid roller bearings. ASTM Subcommittee F34.01 on Rolling Element has now developed a standard for hybrid roller bearings, ASTM F2730/F2730M , Specification for Silicon Nitride Cylindrical Bearing Rollers. Subcommittee F34.01 is under the…
