The U.S. Federal Aviation Administration has selected ASTM International Committee F38 on Unmanned Aircraft Systems to develop industry standards for small unmanned aircraft systems. These standards will allow sUAS to file and fly missions in the national airspace alongside manned aircraft. According to Rocklin Gmeiner, director, federal/civil programs, Raytheon, and chairman of F38.01, one of…, Technical Contact:, Rocklin Gmeiner, Raytheon Co., Arlington, Va., Phone: 703-284-4308, regmeiner@raytheon.com, ASTM Staff Contact:, Daniel Schultz, Phone: 610-832-9716; dschultz@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8507/Feb2010

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

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 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…
