ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications, has approved two new standards that cover architectural coating touch-up properties and ink stainblocking of paint systems. Both new standards are under the jurisdiction of Subcommittee D01.42 on Architectural Coatings., Touch-Up Properties, When a home is being constructed, paints are subjected to a wide variety of drying conditions, which can lead to differences in appearance between the original coat and subsequent touch-up areas after the paint has fully cured. A new standard, ASTM D7489 , Practice for Evaluating Touch-Up Properties of Architectural Coatings Under Various Environmental Conditions, covers variations in color,…, Ink Stainblocking, Paint companies and raw material suppliers will be able to use a new ASTM standard to assess the capability of architectural coatings for blocking ink stains from bleeding through to a topcoat. The standard, ASTM D7514 , Test Method for Evaluating Ink Stainblocking of Architectural Paint Systems by Visual Assessment, represents a compilation and synthesis of methods that are currently being used…

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…

Hydrogels are highly hydrated polymer networks that can be used in the regenerative medicine field as “scaffolding” for the repair of tissue. A proposed new ASTM standard will provide those working in regenerative medicine with a means of characterizing hydrogels. The work item, ASTM WK21927 , Guide for Characterization of Hydrogels Used in Regenerative Medicine, is under the jurisdiction of…

Each year, approximately 400,000 healthcare workers (HCW) in the United States suffer accidental injury from needles and other medical sharps while tending to patients. These injuries can result from injections, drips, infusions, blood-taking, surgery, biopsy and research, among other causes. Each of these accidents carries a small but documented risk of transmitting more than 60 blood-borne…

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…

Participation is welcome in a task group that is developing a proposed new ASTM International standard for manufacturers of vascular graft tissue engineered medical products. WK21657 , Guide for Characterization and Assessment of Vascular Graft Tissue Engineered Medical Products (TEMPs), is being developed by a task group under the jurisdiction of subcommittee F04.04 on Tissue Engineered Medical…

Subcommittees F04.41 - F04.46 , which deal with Tissue Engineered Medical Products (TEMPs), part of ASTM International Committee F04 on Medical and Surgical Materials and Devices, will meet Oct. 27-28 at the National Physical Laboratory in Teddington, United Kingdom. The meeting will focus on the ongoing development of several proposed TEMPs-related standards. Several TEMPS standards are…

Two new standards demonstrate the broad range of practices and test methods currently being developed by ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications. The new ASTM standards will be used in the realms of color reproduction and contact angle measurement. Achieving Consistent Color Reproduction Developed by Subcommittee D01.56 on Printing Inks, ASTM…
