Wet blue and wet white are intermediate products used by tanneries that process natural hides and skins into leather. Natural fats and oils need to be largely removed from wet blue and wet white for leather processing to be done properly, but no standard had previously existed to evaluate the effectiveness of such removal. ASTM International Committee D31 on Leather has now developed such a…

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

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…
