ASTM Paint Committee approves zirconium treatment standard.
Press Release Summary:
Sep 29, 2010 - ASTM International Committee D01 on Paint and Related Coatings, Materials, and Applications developed ASTM D7639, Test Method for Determination of Zirconium Treatment Weight or Thickness on Metal Substrates by X-Ray Fluorescence, to aid production of fit-for-purpose and cost-effective parts. Applicable along process line or in QC lab, standard will be used to measure zirconium treatment weight or thickness applied to metal substrates.

ASTM Paint Committee Approves Standard for Zirconium Treatment
Press release date: Sep 21, 2010
According to Christelle Petiot, XRF coatings product manager, Oxford Instruments Analytical, U.K., "This standard will be used to measure the zirconium treatment weight or thickness applied to metal substrates, either along the process line, or in the quality control lab." In both cases X-ray fluorescence instruments are used; handheld XRF instruments are typically used along the process line for rapid quality control with no sample preparation, and benchtop XRF instruments are used in the quality control lab. The XRF instruments are used to provide qualitative and quantitative data about the metals.
"ASTM D7639 shows users the performance (precision) that can be achieved by following its simple procedure and using the instrumentation defined in the method," says Petiot. The next step for Committee D01 and its Subcommittee D01.53 on Coil Coated Metal is to develop methods for other treatments such as chromium and titanium. The committee welcomes participation from all interested parties, particularly coil coater professionals.
