Paint and Coating Technologists Sought to Develop Standard for High-Gloss Surfaces

ASTM Subcommittee E12.11 on Visual Methods seeks users and producers of high-gloss paints and coatings to join its development of a Standard Practice for the Measurement of Distinctiveness of Image of High Gloss Surfaces with Visual-Instrumental Devices. The proposed standard will offer a measurement of “appearance quality-control” for ultra high-gloss surfaces such as those on automotive vehicles and coffins.

“By virtue of the data we’ve collected for appearance characterization,” says Andrew Rutkiewic, president, Product Technology Consultants, Inc., Tijeras, New Mexico, “the [proposed practice] will describe a demonstrated methodology for the characterization for surface appearance quality with a portable, inexpensive instrument. It will offer a significantly more discriminating way of measuring the quality of appearance both in a development mode for finishes, and in an application and use mode for automotive manufacturers and aircraft manufacturers. And it will measure the quality of the job done by refinish shops.”

The standard will also measure loss of appearance quality over time.

A subcommittee task group developing the standard needs additional involvement from paint and coatings technologists. “The time is right for all interested parties to get their oar in the water,” says Rutkiewic. The present group includes color and appearance technologists specializing in color appearance, measurement, and characterization. They seek stakeholders in automotive or aircraft manufacturing and body repair, chemists, quality-control or application engineers, paint and coatings professionals (including academics and researchers), members of the Society of Automotive Engineering, paint and coating societies, and other standards developers.

The subcommittee is part of ASTM Committee E12 on Color and Appearance, which develops standards addressing color and appearance problems. To participate or offer feedback, contact Rutkiewic (phone: 505/281-7820). Committee E12 meets June 23-25 in San Diego, Calif., in conjunction with the meetings of CIE (International Commission on Illumination). For meeting or membership details, contact Maxine Topping, manager, Technical Committee Operations, ASTM International (phone: 610/832-9737). //
