Durability of wood and wood-based products. Determination of treatability of timber species to be impregnated with wood preservatives. Laboratory method Ingestion-build-141043 b) Condition monitoring1 Scope This Technical Report describes a laboratory method for the determination of the treatability of wood in order to determine the likely reaction of different wood species to impregnation with wood preservatives. It can also be used to investigate variation between samples of the same species but of different origin.
