Standards developed by ASTM International Committees F20 on Hazardous Substances and Oil Spill Response and E47 on Biological Effects and Environmental Fate play a role in both the initial response and follow-up to oil spills. The recent spill in the Gulf of Mexico highlights the importance of standards that cover all aspects of oil spill response and cleanup. F20 on Hazardous Substance and Oil…

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…

Vessel-mounted cameras can be effectively and economically used by ship crews investigating and responding to an oil spill. ASTM International Committee F20 on Hazardous Substances and Oil Spill Response is currently developing a proposed new standard on use of cameras in this realm. WK24607 , Specification for the Design and Use of Vessel-Mounted Camera Systems for Oil Spill Response, is under…

Oil skimmer nameplate capacities are used to evaluate system performance for spill response planning standards. While manufacturers had been free to state any value as to the theoretical capacity of an oil skimmer, a new ASTM International standard provides a test that can be used to establish a realistic capacity. The standard, F2709 , Test Method for Determining Nameplate Recovery Rate of…

All interested parties are invited to participate in the standards developing activities of ASTM International Committee F20 on Hazardous Substances and Oil Spill Response. Among the committee’s recent activities are the approval of a new standard on oil spill containment booms and work on a proposed standard on the use of in-situ burning of oil spill in marshes. Manufacturers of containment…

A recently approved revision to ASTM International standard C 150 , Specification for Portland Cement, includes three significant technical changes to the document. The changes are part of a joint effort between ASTM and the American Association of State and Highway and Transportation Officials to harmonize C 150 with AASHTO’s standard, M 85, Specification for Portland Cement. C 150 is under the…

Navies and coast guards around the world will be the likely users of a new standard developed by ASTM International Committee F20 on Hazardous Substances and Oil Spill Response, F 2533 , Guide for In-Situ Burning of Oil in Ships or Other Vessels. The standard, under the jurisdiction of Subcommittee F20.15 on In-Situ Burning, covers the use of in-situ burning directly in ships and other vessels as…

Although alkali resistant glass fibers have been commercially available for more than 30 years, there has not been an official standard that clearly defines what is required to make glass fibers resistant to alkali attack without the need for protective coatings. ASTM International Committee C27 on Precast Concrete Products has recently developed such a standard, C 1666/C 1666M , Specification…

Ineffective removal of grease from restaurants poses a variety of serious environmental problems. Large quantities of grease in public sanitary sewer systems can cause stoppages of piping networks and create costly and time-consuming problems at treatment plants. Sewer backups resulting from grease can also create health hazards when raw sewage backs up into homes or businesses. While grease…
