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.
