Wood preservatives - Artificial weathering of treated wood prior to biological testing - UV-radiation and water-spraying procedure

Asnjë informacion i shtuar.

This document specifies a method for the artificial weathering of test specimens of treated wood, which are used in the testing of the biological efficacy of wood preservatives. This method is applicable to: a) the pre-conditioning of test specimens prior to their being subjected to a biological test; or b) assessment of loss of effectiveness by comparing the performance in a biological test of treated test specimens subjected to this procedure with others that have not undergone any artificial weathering procedure. NOTE The method can also be used for pre-conditioning of wood-based panel products, which may or may not have received preservative treatment.
