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…

Flow characteristics of fine metal powders are important in filling dies for pressing of powder metallurgy compacts, which are later sintered and sometimes machined into finished parts. The flow rate, as measured by a new ASTM standard, determines the flow necessary for a precise quantity of powder to be introduced into the die. The new standard, B964 , Test Methods for Flow Rate of Metal Powders…

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…

Two recently approved ASTM International standards provide user-friendly tests for properties of sintered metallurgy products. The new standards, developed by Subcommittee B09.04 on Bearings, are ASTM B962 , Test Methods for Density of Compacted or Sintered Power Metallurgy (PM) Products Using Archimedes’ Principle, and ASTM B963 , Test Methods for Oil Content, Oil-Impregnation Efficiency and…

Drawing on the best practices of the U.S. Federal Highway Administration and the states, ASTM International Committee E17 on Vehicle-Pavement Systems has developed a new standard, E 2561 , Practice for Installation of Inductive Loop Detectors. E 2561 is under the jurisdiction of Subcommittee E17.52 on Traffic Monitoring. Inductive loop detectors are installed in sawed slots in roadway pavement…

Airport operators, military pavement maintenance personnel, transportation regulatory agencies and state highway departments will all benefit from the approval of a new ASTM standard for measuring skid resistance. The standard, E 2340 , Test Method for Measuring the Skid Resistance of Pavements and Other Trafficked Surfaces Using a Continuous Reading, Fixed-Slip Technique, was developed by…

Two new standards developed by ASTM International Committee E17 on Vehicle Pavement Systems will provide uniform specification and test criteria for agencies and manufacturers that deal with traffic monitoring devices. The new standards, which are both under the jurisdiction of Subcommittee E17.52 on Traffic Monitoring, are E 2300 , Specification for Highway Traffic Monitoring Devices, and E 2532…

A proposed new standard being developed by ASTM International Committee B09 on Metal Powders and Metal Powder Products offers a solution to the challenge of handling and characterizing very fine powders. Subcommittee B09.02 on Base Metal Powders is developing the proposed standard, WK13023 , Test Method for Determination of Tap Density of Metallic Powders by a Constant Volume Measuring Method. …

A strong demand from the aerospace sector has made it challenging for industry to supply heat-treated plate for both aerospace and other applications. To increase heat-treated plate production capacity, ASTM International Committee B07 on Light Metals and Alloys has developed a new standard, B 947 , Practice for Hot Rolling Mill Solution Heat Treatment for Aluminum Alloy Plate. The new standard…

Conventionally processed powder metallurgy materials often exhibit open microporosity at the surface. While it is a natural part of the process, this microporosity can affect the measurement of surface finishes. To cover this and other issues that arise from measuring the surface finish of powder metallurgy, ASTM International Committee B09 on Metal Powders and Metal Powder Products has developed…
