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: Section Summary of Test Method 4 Apparatus 6 Reagents 7 Wood 8 Test Fungi 9 Culture Media 10 Preparation of Inoculum 11 Preparation of Test Chambers 12 Treatment of Samples 13 Inoculation and Incubation 14 Evaluation of the Test 15 Report 16 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
