PD CEN/TS 16663 discusses the durability of wood and wood-based products. PD CEN/TS 16663 specifies a method for determining the leaching of active ingredients or other compounds from treated wood by a semi-field method for use class 3 (outdoor above ground).
The preservative-treated wood can be tested with or without subsequently surface coating or other water-repellent treatment. The method in PD CEN/TS 16663 is applicable to the testing of commercial or experimental preservatives or paint systems applied to timber by methods appropriate to commercial practice.
PD CEN/TS 16663 on the durability of wood and wood-based products is useful for:
The leaching from preservative-treated wood into the environment needs to be quantified to enable an environmental risk assessment to be made of the treated wood, e.g., according to the Biocidal Products Regulation, 528/2012. PD CEN/TS 16663 provides you with a semi-field method for the determination of leachate from preservative-treated wood where the preservative-treated wood is not covered and not in contact with the ground or water.
The method in PD CEN/TS 16663 is a semi-field procedure for obtaining water samples (leachate) from treated wood exposed out of ground contact, during natural exposure. The quantities of emissions in the leachate are related to the surface area of the wood and can be used in scenarios for the environmental risk assessment of the treated wood.
