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…

Code words have historically been used in the electrical conductor industry as a simple method of identifying the construction details of an overhead conductor product. A proposed new ASTM standard will list code word names and provide a means to register and publish new code words. ASTM WK28737 , Specification for Electrical Overhead Conductor Code Word Names, is being developed by Subcommittee…, ASTM Committee B01 Next Meeting:, Oct. 13, October Committee Week, San Antonio, Texas, Technical Contact:, Gordon Baker, General Cable, Highland Heights, Ky., Phone: 859-572-8493; gbaker@generalcable.com, ASTM Staff Contact:, Jennifer Rodgers, Phone: 610-832-9694; jrodgers@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8613

Silver-, nickel- and tin-coated flat conductors are currently used in a variety of electronic applications, including computer, and in the military and commercial aerospace industries. Despite this use, flat conductors made of these materials are not covered by established standards. ASTM International Committee B01 on Electrical Conductors is now developing the following three standards to cover…, ASTM Committee B01 Next Meeting: , April 21, 2010 , April Committee Week, St. Louis, Mo., Technical Contact:, Stephen Childers, IWG High Performance Conductors Inc., Inman, S.C., Phone: 864-472-9694; stephen.childers@iwghpc.com, ASTM Staff Contact:, Jennifer Rodgers, Phone: 610-832-9694; jrodgers@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8442/Dec2009

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…

ASTM International Committee B01 on Electrical Conductors has approved a new standard for tin-coated annealed copper wire. The standard, B965 , Specification for High Performance Tin-Coated Annealed Copper Wire Intended for Electrical and Electronic Application for Solderability, was developed by Subcommittee B01.04 on Conductors of Copper and Copper Alloys . Stephen Childers, process engineer,…

The main purpose of any grounding product is to provide a low-resistance path for fault currents to follow to the ground, which will ultimately protect the integrity of the power system and maintain a safe operating environment. ASTM International Committee B01 on Electrical Conductors is developing a proposed new standard to annealed concentric-lay-stranded copper-clad steel conductors. While…
