This Standard specifies a method of test for wood
preservatives that are intended for use in wood to be exposed to
the weather out of contact with the ground without the
additional protection of a surface coating (i.e. Use Category 3).
The method should be used in situations where the AWPA
Standard E9, a method of test for wood preservatives applied in
combination with a coating, is not applicable.
The main objective of the method is to evaluate the
relative effectiveness of the preservative, applied to jointed
samples of pine sapwood by a treatment method relevant to its
intended practical use. Effectiveness is evaluated relative to a
reference preservative treatment. The method is concerned
with the protection against decay after exposure to the
complete range of micro-organisms occurring under natural
conditions. It also takes into account physico-chemical effects
of weathering on the performance of the preservative treated
wood.
