Application Summary AI generated

This standard specifies the X-ray fluorescence spectroscopy method for analyzing the content of CCA (chromated copper arsenate) and ACQ (alkaline copper quaternary) preservatives in treated wood and wood preservative solutions. It is applied in the wood preservation industry for quality control, environmental monitoring, and regulatory compliance testing of treated timber used in construction, outdoor structures, and utility poles. The method enables rapid, non-destructive quantification of preservative retention levels to ensure treated wood meets safety and performance specifications.
