ActiveMethod for analysing CCA and ACQ in preservative-treated wood and wood preservatives by X-ray fluorescence spectroscopy
X射线荧光能谱仪测定防腐木材和木材防腐剂中CCA和ACQ的方法
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.
