ASTM International is developing ASTM WK17368 - Test Method for Determination of Zirconium Treatment Weight on Metal Substrates by X-Ray Fluorescence.
The proposed standard is being drafted by Subcommittee D01.53 on Coil Coated Metal, which is part of ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications.
Coaters need a reliable method of measuring the coating weight of zirconium treatments on metal substrates, according to Robert Cianflone, president, Cianflone Scientific Instruments Corp. and a member of Subcommittee D01.53.
The proposed standard would be used at coil coater plants and at R&D and analytical laboratories.
"Surface treatments containing zirconium appear to be one of the future replacements for zinc phosphate in the automotive industry as well as the elimination of chromium pretreatment in the coil coating industry," said Cianflone. "So, it will become more prominent in other steel-related applications."
The techniques described in the proposed standard will be applicable for determination of the coating weight of zirconium or total weight of a zirconium-containing treatment or both on a variety of metal substrates.
