ASTM International Subcommittee D01.44 on Traffic Coatings, part of Committee D01 on Paint and Related Coatings, Materials, and Applications, is working on two proposed new standards covering the sampling of waterborne traffic paint and glass bead gradation measurement.
Proposed standard ASTM WK22312, Practice for Drum and Tote Sampling of Waterborne Traffic Paint, addresses laboratory sampling issues. Ensuring that traffic paint taken from the field is tested properly in laboratories is a concern. Interested parties are invited to join in the development of the standard and can contact Greg Shay, the chair of Task Group D01.22.02, at shaydg@dow.com.
ASTM WK23758, the proposed standard for Test Method for Measuring Gradation of Glass Beads Using a Flowing Stream Digital Image Analyzer, will help in the production and quality control of glass beads. Glass beads are added to traffic paint during manufacturing to ensure paint retroflectivity, especially at night. Gary Ware, an ASTM D01 committee member, said that all participation is welcome, but the subcommittee especially needs technical people. He can be contacted for more information at gary.ware@swarco.com.
