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 new ASTM International standard can now be used to set strength requirements for condition 0 bicycle frames. Condition 0 bicycles, typically referred to as sidewalk bikes, are designed for young children riding under the supervision of an adult. The new standard, ASTM F2843 , Specification for Condition 0 Bicycle Frames, was developed by Subcommittee F08.10 on Bicycles, part of ASTM…

Committee F08 on Sports Equipment and Facilities has developed a new ASTM International standard that measures the stiffness and elasticity of baseballs and softballs relative to cylindrical collisions. The new standard, ASTM F2845 , Test Method for Measuring the Dynamic Stiffness (DS) and Cylindrical Coefficient of Restitution (CCOR) of Baseballs and Softballs, is under the jurisdiction of…

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

New Lead Content in Turf Fibers Standard Developed by ASTM Sports Equipment and Facilities CommitteeTwo separate events have led to the development of a new ASTM International standard on lead content in turf fibers. First, after lead was found in some synthetic turf fields in 2008, field owners and turf suppliers were confused as to the proper procedure for measuring the lead content in the fibers. Different test procedures would yield different results so there was need for a standardized…

The adoption of quick-release devices on bicycles has led to a heightened potential for injuries due to front wheel separations. A new ASTM International standard defines the performance of primary and secondary wheel retention systems in order to prevent unintended wheel separation. The new standard, ASTM F2680 , Specification for Manually Operated Front Wheel Retention Systems for Bicycles, was…

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…

Subcommittee F08.57 on Eye Safety for Sports is continuing its work to develop and maintain eyewear standards for a variety of sports. The subcommittee, part of ASTM International Committee F08 on Sports Equipment and Facilities, is currently at work on developing a new standard for motorcycle/moped/snowmobile goggles and revising an existing standard for skier goggles. According to Charley…
