Traffic monitoring is a means of counting and classifying vehicles and measuring vehicle flow characteristics, such as vehicle speed, lane occupancy, turning movements and other items typically used to portray traffic movement. In order for traffic monitoring data to be assessed properly, information on how the data were collected, edited, summarized and reported must be provided. This obligation…

A new ASTM subcommittee seeks to acknowledge the ongoing advances being made in the field of nanostructured inorganic coatings. B08.16 on Nanostructured Coatings, part of ASTM International Committee B08 on Metallic and Inorganic Coatings, is currently developing its first proposed standard, ASTM WK29468 , Specification for Galvanic Protection of Steel Using a Nanostructured Coating of 95 % Zinc…

A new ASTM International standard will provide a fast and effective way to test production lots of thermoplastic elastomers in order to quantify and predict how well they process and what ultimate physical properties will be imparted to final molded or extruded products. ASTM D7605 , Test Method for Thermoplastic Elastomers — Measurement of Polymer Melt Rheological Properties and Congealed…

The impact of health care related infections is a global concern, and hands are a leading means of direct or indirect transport of infectious microorganisms. A task group within Subcommittee D11.40 on Consumer Rubber Products has begun to develop standards focused on preventing that transfer through the use of antimicrobial agents on gloves. D11.40 is part of ASTM International Committee D11 on…

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…

Residual accelerator chemicals in medical gloves appear to be a leading cause of allergic contact dermatitis in health care workers. A new ASTM International standard allows rubber glove manufacturers to monitor the level of residual chemicals in their end products and to potentially make manufacturing changes to reduce allergen levels. The new standard, D7558 , Test Method for Colorimetric/…

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…

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…

Producers of fluorocarbons are invited to join in the ongoing standards developing activities of ASTM International Committee D26 on Halogenated Organic Solvents and Fire Extinguishing Agents. The committee has recently approved a new standard, ASTM D7509 , Specification for Fluorocarbon Feedstock Grade Chloroform, under the jurisdiction of Subcommittee D26.08 on Halogenated Organics Used as…

Once approved, a proposed new ASTM standard would provide the U.S. Food and Drug Administration and personal lubricant manufacturers a means to evaluate the effect of a lubricant on the physical integrity of condoms. No standard currently exists for this type of testing. Manufacturers of condoms and rubber gloves as well as personal lubricants are welcome to join in the development of ASTM…
