This document specifies an evaporative ageing procedure, applicable to test specimens of wood which have been previously treated with a wood preservative, in order to evaluate any loss of effectiveness when these test specimens are subsequently subjected to biological tests.

This document specifies a method for the leaching of test specimens of wood which are used in the testing of the biological efficacy of wood preservatives.

This standard 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 leaching procedure.

NOTE          The method may also be used for pre-conditioning of wood-based panel products which may or may not have received preservative treatment.
