Since the appearance of the first California-type models around 1940, the profilograph has been a popular device used for quality control in the construction of pavements. Both roadway and airfield landing agencies have adopted roughness indexes computed from profilograph-derived measurements as a level of construction quality. Emerging high-speed inertial profilers can now quickly collect…

A proposed new standard being developed by ASTM International Committee E17 on Vehicle-Pavement Systems will be the first to describe how truth-in-data should be applied to traffic monitoring data collection, summarization and reporting. WK25280 , Practice for Highway Traffic Monitoring Truth-in-Data, is under the jurisdiction of Subcommittee E17.52 on Traffic Monitoring. Current traffic…

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…

The ASTM International Proficiency Testing Center is pleased to offer a 2010 Proficiency Testing Program on Thermal Analyses of Plastics (TAP) to laboratories who need a statistical quality assurance tool that will enable them to improve and maintain a high level of performance in conducting ASTM Differential Scanning Calorimetry (DSC), Oxidative-Induction Time (OIT) by Differential Scanning…, ASTM D3418, , Standard Test Method for Transition Temperatures and Enthalpies of Fusion and Crystallization of Polymers by Differential Scanning Calorimetry (DSC);, ASTM D3850, , Standard Test Method for Rapid Thermal Degradation of Solid Electrical Insulating Materials By Thermogravimetric Method (TGA); and, ASTM D3895, , Standard Test Method for Oxidative-Induction Time of Polyolefins by Differential Scanning Calorimetry. For each test trial, laboratory participants receive two sample materials along with interactive electronic data report forms and test instructions. Using the specified ASTM program tests, participating laboratories conduct the tests of their choice that they routinely run. Upon completion of…

Being able to compile and interpret data on how traffic turns through an intersection could have an impact on future environmental and safety decisions regarding intersection geometry and traffic control. However, until recently no standard has existed to properly obtain and use this data. Now, ASTM International Committee E17 on Vehicle-Pavement Systems has approved E2667 , Practice for…

All interested parties in the glass industry are invited to participate in the development of a proposed new standard guide for the safe handling of annealed glass. The new standard will be developed by a task group within ASTM Committee E34 on Occupational Health and Safety. A small group from industry and OSHA met in Rossford, Ohio, in March to discuss this new activity. The task group plans to…

ASTM International Committee A06 on Magnetic Properties has approved the first in a series of proposed standards on permanent magnet materials. The new standard, A 1054 , Specification for Sintered Ceramic Ferrite Permanent Magnets, as well as the other proposed standards, are under the jurisdiction of Subcommittee A06.02 on Material Specifications. While ASTM has long had standards covering…
