The texture - often called the profile - of concrete is one of the most important characteristics of a coating or overlayment bonding. A new ASTM International standard now fulfills the need within the concrete surface preparation field for a means of measuring and permanently replicating the profile of a concrete coated building surface. ASTM D7682 , Test Method for Replication and Measurement…

The proper selection of assessors can have a direct effect on the outcome of any sensory or consumer test. A proposed new ASTM International standard will help users determine appropriate assessors, give general guidelines for ways to select and recruit respondents, and list the benefits and drawbacks in selecting certain assessors. The proposed new standard, ASTM WK30847 , Guide for Selection of…

Zirconium is used as an anti-corrosive finishing/surface treatment on metal substrates. If the coating of zirconium is too thin, then the sought-for metal property will not be achieved. Similarly, applying too thick a coat means that treatment material is wasted and so is money. Therefore, ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications has developed a…, ASTM Committee D01 Next Meeting:, Jan. 30-Feb. 1, 2011, January Committee Week, Baltimore, Md., Technical Contact:, Christelle Petiot, Oxford Instruments Analytical, High Wycombe, Buckinghamshire, United Kingdom; christelle.petiot@oxinst.com, ASTM Staff Contact:, Jeffrey Adkins, Phone: 610-832-9738; jadkins@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8685/Sept2010

ASTM grain size is a property written into many specifications for metals, with finer grain sizes generally indicating better mechanical properties, such as formability. While measuring certain materials for such properties can be difficult, electron backscatter diffraction can provide precise determinations as well as give information on grain size distribution and statistics. A new ASTM…

A recent revision to ASTM International standard E384 , Test Method for Knoop and Vickers Hardness of Materials, expands the range of its coverage. The standard is under the jurisdiction of Subcommittee E04.05 on Microindentation Hardness Testing, part of ASTM International Committee E04 on Metallography. The revision incorporates ASTM E92 , Test Method for Vickers Hardness of Metallic Materials…

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…
