Two new ASTM International standards on rescue litters and fixed anchorages will contribute to the safety and efficiency of search and rescue operations. Both standards were developed by Subcommittee F32.01 on Equipment, Testing and Maintenance, part of ASTM International Committee F32 on Search and Rescue., BASKET TYPE RESCUE LITTERS, Until the development of ASTM F2821 , Test Methods for Basket Type Rescue Litters, there had not been a standardized means for manufacturers to test these rescue devices, according to John McKently, Los Angeles County Sheriff's Department, and an F32 member. “ASTM F2821 was developed because there was no standard available that allowed manufacturers to test litter products in the same way,” says…, FIXED ANCHORAGES, According to McKently, the impetus for the development of ASTM F2822 , Specification for Fixed Anchorages Installed on Structures Used for Rope Rescue Training, was similar to that of ASTM F2821. In this case, the standard was developed to provide minimum strength requirements for anchorages permanently installed or attached to training towers or other structures used for rope rescue training. “…, ASTM Committee F32 Next Meeting:, Nov. 7-10, in conjunction with the International Technical Rescue Symposium, Golden, Colo., Technical Contact:, John McKently, Los Angeles County Sheriff's Department, Glendale, Calif., Phone: 818-247-3209; jmckently@earthlink.net, ASTM Staff Contact:, Thomas O'Toole, Phone: 610-832-9739; totoole@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8654

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…

After a 35-year-absence, the natural cement industry is being revived and, along with it, a long-withdrawn ASTM International standard. Until it closed in 1970, the Century Cement Company in Rosendale, N.Y. was the last company to manufacture natural cement. Up to that point, Rosendale had been the center of the industry, the source of more than half of all natural cement produced in the U.S.…
