This test method determines the relative effectiveness of wood preservatives in small wood specimens exposed to a natural marine environment. It is not within the scope of this procedure to determine the retention levels necessary for protection of commercial size piles and timbers. This Standard is based on ASTM D2481.

This test method is useful for determining the rela-tive efficacy of various treatments against naturally occur-ring wood-destroying agents. It is an initial means for esti-mating the tolerance limits of the biologically destructive agents or the threshold values of the chemical preservative, or both.

This test method is a qualitative method designed to provide a reproducible means of establishing relative efficacy between experimental chemical treatments and a reference chemical treatment (i.e. creosote, CCA or ACZA).

This Standard may involve hazardous materials, operations and equipment. This Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
