Traffic paint plays an important role in maintaining the safety of roads. Subcommittee D01.44 on Traffic Coatings, part of ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications, is currently working on two proposed new standards covering the sampling of waterborne traffic paint and glass bead gradation measurement., WATERBORNE TRAFFIC PAINT, Ensuring that traffic paint taken from the field is tested properly in laboratories is a concern of paint suppliers as well as private testing laboratories, Department of Transportation labs, DOT striping crews and striping contractors. A proposed new ASTM standard, ASTM WK22312 , Practice for Drum and Tote Sampling of Waterborne Traffic Paint, addresses laboratory sampling issues. According to…, GRADATION OF GLASS BEADS, Glass beads added to traffic paint during manufacturing are necessary to ensure paint retroreflectivity, especially at night. A proposed new standard, ASTM WK23758 , Test Method for Measuring Gradation of Glass Beads Using a Flowing Stream Digital Image Analyzer, will be useful in the production and quality control of glass beads. “Digital camera technology combined with high speed computers has…

Coinciding with Earth Day 2009, the inaugural meetings of ASTM International Committee E60 on Sustainability covered standards work, an expanded sustainability database, a student liaison subcommittee and more. Ninety-five stakeholders from a range of industries met April 21-23 in Vancouver, British, Columbia, Canada, and discussed best practices for sustainability and the potential to…, Life Cycle Assessment Workshop to Be Held in October, On Sunday, Oct. 18, and Monday, Oct. 19, Committee E60 will host a workshop on life cycle assessment and both its theory and practice. The purpose is to share information on the effective use of LCA methodology in supporting standards development. The workshop will be held during the ASTM October committee week meetings in Atlanta, Ga., E60 Develops Submission Criteria and Expands Online Sustainability Database, Through new criteria and a new task group, Committee E60 has expanded the scope of its online sustainability database, and it encourages all ASTM committees and outside organizations to submit sustainability-related standards for possible inclusion in the resource. According to Meadows, the sustainability database fills a void in having one place to gather sustainability standards from both ASTM…, Proposed Standards from New Student Liaison and Affairs Subcommittee, To give a voice to ASTM student members who represent universities around the world, Committee E60 has established Subcommittee E60.95 on Student Liaison and Affairs. Sustainability, notes Meadows, is about managing resources today so that they are available to future generations, and as such, students have a vested interest in the work of the committee. E60 plans to communicate with interested…

More effective quality testing of the synthetic, hollow filaments that are often used in the manufacture of lower cost paintbrushes is the purpose of a new standard approved by ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications. The new standard, ASTM D7233 , Test Method for Testing Fracture of Level Paintbrush Filaments, was developed by Subcommittee D01.…

The wettability of a particular solid coating, substrate or pigment on a surface is a key to its effectiveness, as wetting is important to adhesion as well as to the prevention of surface defects such as craters, dewetting and crawling. A new ASTM International standard uses contact angle measurements to determine the wettability of coatings. The new standard, D7490 , Test Method for Measurement…

By necessity, paint used for roadway applications needs to dry quickly. Some multi-component traffic paints cure in less than 10 minutes, some much faster. Because of this speed of curing, these traffic paints and other types of fast-cure (less than 10 minutes) multi-component paints cannot be tested for volatile content using procedures outlined in the ASTM International standard typically used…
