    Significance and Use

    5.1 This test method is useful as a screening procedure for selecting fungicides or formulations for more rigorous field evaluation.

    1. Scope

    1.1 This (laboratory) test method is used for determining the minimum concentration of fungicide, or formulation of fungicides, that is effective in preventing biodeterioration by sapstain fungi and molds in selected species of wood under optimum laboratory conditions.

    Note 1: From the results of this test, commercial treating solution concentrations cannot be estimated without further field tests.

    1.2 The requirements for test materials and procedures are discussed in the following order:



    Summary of Test Method








    Test Fungi


    Culture Media


    Preparation of Inoculum


    Preparation of Test Chambers


    Treatment of Samples


    Inoculation and Incubation


    Evaluation of the Test
