【国外标准】 Standard Test Method for Accelerated Evaluation of Wood Preservatives for Marine Services by Means of Small Size Specimens (Withdrawn 2014)

This test method is useful in determining the relative efficacy between various treatments and naturally occurring wood-destroying agents. It is an initial means of estimating the tolerance limits of the biologically destructive agents or the threshold values of the chemical preservative, or both.This test method is not intended to provide quantifiable reproducible values. It is a qualitative method designed to provide a reproducible means of establishing relative efficacy between experimental contract levels.1.1 This test method covers the relative effectiveness of wood preservatives in small wood specimens exposed to a natural marine environment. It is not within the scope of this test method to determine the retention or duration of protection for commercial size piles and timbers.1.2 The requirements for preparing the material for testing and the test procedures appear in the following order: SectionSummary of Test Method Test Specimens Pretreatment Handling Treatment Procedure Post-Treatment Handling Assembly of Test Specimens Exposure Inspection Evaluation of Results Reports 1.3 This standard does not purport to address all of the safety concerns, if any, 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.
