    Significance and Use

    This test method is useful in the development of new wood preservatives and preservative systems by evaluating the minimum preservative retention to prevent decay under laboratory conditions. The results are used to facilitate target retentions in subsequent tests for effectiveness against termites (see Test Method D 3345) and in field stakes (see Test Method D 1758). The sections on Treatment and Preservative Permanence are referenced by other ASTM standards. The test method assumes that the test blocks exposed to certain conditions after treatment will achieve equilibrium, and will return to the same equilibrium after exposure to fungi. This assumption may lead to weight loss that is not due to decay. The test uses live cultures of fungal organisms that require careful colonization, storage, and feeding to remain viable strains.

    1. Scope

    1.1 This test method covers determination of the minimum amount of preservative that prevents decay of selected species of wood by selected fungi under optimum laboratory conditions.

    1.2 The requirements for preparation of the material for testing and the test procedure appear in the following order:
