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…

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…

The presence of lead in toys and other consumer products continues to make headlines. The Consumer Product Safety Improvement Act, a United States law enacted in August 2008, addresses the lead issue and makes provisions for the use of X-ray spectrometry in testing for lead content. To aid the toy and consumer products industries in using X-ray spectrometry for lead detection and meet the…

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…

No industry standard currently exists that addresses the vacuum sealing requirements of knife-edged flanges for high vacuum applications. Existing international standards focus on interchangeability of the hardware, but do not address the reliability of the seal. ASTM International Committee E42 on Surface Analysis is now working on a proposed standard on the subject, WK21206 , Specification…

A 2002 workshop on galling wear held by ASTM International Committee G02 on Wear and Erosion provided the impetus for the development of a new standard, ASTM G196 , Test Method for Galling Resistance of Material Couples. The new standard is under the jurisdiction of Subcommittee G02.40 on Non-Abrasive Wear. According to Scott Hummel, Ph.D., associate professor, head of the department of…
