Test panel standards being developed
26. July 2011
A proposed new ASTM International standard will be the first that addresses test panel preparation and rating specifically for corrosion testing for coatings on building projects.
ASTM WK30920, “Guide for Corrosion Test Panel Preparation and Rating of Coil-Coated Building Products,” is being developed by Subcommittee D01.53 on Coil Coated Metal, part of ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications.
According to Ted Best, a scientist at Valspar Corp., and D01.53 member, the standardization of test panel configurations and ratings would allow benchmark comparisons across a broad range of products that includes substrates, pretreatments and coatings. Producers will be able to use the proposed standard, once it has been approved, to develop new products, while users will employ it to verify and compare product performance.
“These comparisons lead to better understanding of product performance as a function of environment, better service life predictions and shorter product development cycles,” says Best.
All interested parties are welcome to join in the development of ASTM WK30920 by visiting www.astm.org/JOIN
“Coil coaters and metal building manufacturers are especially welcome for the valuable input they can provide based on their experience and understanding of market requirements,” says Best.
ASTM International is one of the largest international standards development and delivery systems in the world. ASTM International meets the World Trade Organization (WTO) principles for the development of international standards: coherence, consensus, development dimension, effectiveness, impartiality, openness, relevance and transparency. ASTM standards are accepted and used in research and development, product testing, quality systems and commercial transactions.
