Field Ground Contact Post Test Method

 

Wood posts are impregnated with an appropriate series of retentions of preservative or other protectant, and then handled, prior to exposure in the field, according to specified procedures.

The treated posts are exposed in the ground to the action of wood-destroying fungi and/or termites in field plots. An index of condition determined from grades assigned to the stakes for degree of decay and termite attack, in the course of periodic inspections, is used to express results periodically and at the termination of the test. A depletion study may be performed for each active preservative component and retention in order to measure the permanence of the preservative.

Around the world there are a number of different methods used for field post tests. One method that has been standardized is the AWPA Standard E8 test.
