This standard specifies a field test method for evaluating the relative performance of wood treated with preservatives in a severe Use Category 3B exposure. It is designed to test wood preservative systems intended for use in exterior (fully exposed to the weather) above ground (no direct ground or soil contact) exposures where the wood does not have any additional protection provided by a surface coating. The test method evaluates the performance of treated wood in a high moisture field exposure where it is subjected to the wide range of naturally occurring decay fungi and other micro-organisms present in the testing environment. This test method is intended to be a screening test. It may also be used to provide information for standardization of protection treatments. With appropriate adjustments, this method may also be used to generate data on the relative performance of other methods of wood protection such as wood modification, as well as the natural durability of wood. Testing and evaluation of wood and preservative systems intended for above ground exterior applications where a surface coating is used should use AWPA Standard E9.
