Owners and specifiers of steel building projects will be the primary users of a new ASTM International standard, ASTM A1068 , Practice for Life-Cycle Cost Analysis of Corrosion Protection Systems on Iron and Steel Products. The new standard was developed by Subcommittee A05.13 on Structural Shapes and Hardware Specifications, part of ASTM International Committee A05 on Metallic-Coated Iron and…

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…

Subcommittee A05.13 on Structural Shapes and Hardware Specifications is currently working on proposed new standards that would be used by engineers and architects who design with steel fabrications. These proposed standards will be used to evaluate the costs of steel construction over the lifetime of a project and to compare different corrosion protection systems on their impact to this lifetime…

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…

Invented in the early 1990s, the tomographic gamma scanner is used in the nondestructive assay of radioactive waste contained in drums or cans. In the last 10 years, TGS technology has been industrialized, with systems operating in South Korea, the United States and Europe. A new ASTM International test provides users with a means of streamlining TGS procedures and practices, and it will be…

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…

ASTM International Committee A05 on Metallic-Coated Iron and Steel Products has approved a new standard, ASTM A1059/A1059M , Specification for Zinc Alloy Thermo-Diffusion Coatings (TDC) on Steel Fasteners, Hardware and Other Products. The new standard is under the jurisdiction of Subcommittee A05.13 on Structural Shapes and Hardware Specifications. The technology described in ASTM A1059/A1059M…

Galvanized steel products are manufactured and used throughout the world. A new ASTM International standard, A1057/A1057M , Specification for Steel, Structural Tubing, Cold Formed, Welded, Carbon, Zinc-Coated (Galvanized) by the Hot-Dip Process, addresses the galvanizing process as it is used across a variety of industries, including construction, automotive and transportation. The new standard…

In response to requests from fuel producers around the world, ASTM International Committee C26 on Nuclear Fuel Cycle has developed a standard for using the total evaporation method to determine uranium or plutonium composition. The new standard, C 1672 , Test Method for Determination of Uranium or Plutonium Isotopic Composition or Concentration by the Total Evaporation Method Using a Thermal…
