|ICS Code (Wood, sawlogs and sawn timber):||79.040|
significance And Use:
5.1 This test method is useful as a screening procedure for selecting fungicides or formulations for more rigorous field evaluation.
1.1 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:
