ASTM International Subcommittee E34.50 on Health and Safety Standards for Metalworking Fluids has developed three new standards. Two of the recently approved ASTM standards cover aspects of water-miscible metalworking fluids, while the third concerns prevention of dermatitis in the wet metal removal fluid environment., Prevention of Dermatitis, Dermatitis is an inflammatory response of the skin to a chemical or physical agent. While redness, swelling and itching are typical signs of dermatitis, symptoms can be more severe as well. A new ASTM standard, ASTM E2693 , Practice for Prevention of Dermatitis in the Wet Metal Removal Fluid Environment, discusses dermatitis and its causes and presents a comprehensive approach to dermatitis…, Metalworking Fluids, Two new E34.50 standards address the detection of microbial contamination in metalworking fluids: ASTM E2657 , Test Method for Determination of Endotoxin Concentrations in Water-Miscible Metalworking Fluids, and ASTM E2694 , Test Method for Measurement of Adenosine Triphosphate in Water-Miscible Metalworking Fluids. Both ASTM E2657 and ASTM E2694 measure biological contamination in metalworking…, Participation Invited, The subcommittee is currently looking for participants for an interlaboratory study for ASTM E2657 and ASTM E2694 . “We plan to use a single set of MWF for both standards, so labs who are interested in either or both are welcome to participate,” says Passman. “A few labs will run both the ILS’s for both standards, while most will run one or the other.” Subcommittee E34.50 is part of ASTM…

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…
