意义及用途

4.1 真菌生长对油漆和涂料的污染 (模具, 霉菌) 是一个普遍现象, and algal growth contamination can also occur under certain conditions. It is well known that differences in environment, 光, 温度, 湿度, substrate pH and other factors, in addition to the paint combination, can affect the sensitivity of a given painted surface. This test method attempts to provide a way to compare and evaluate the relative properties of different coating formulations under given conditions. This does not mean that a coating that resists growth under these conditions will necessarily resist growth in real-world applications. This method is not intended to simulate or substitute for indoor or outdoor exposure to paint film or related coatings.

笔记 1: The rankings for relative performance of hope are similar to those for outdoor exposure. Coatings designated for use under external conditions should be pretreated by accelerated weathering in a laboratory prior to exposure to fungi. All pre-processing needs to be detailed in the final report. 然而, this test method should not be used as a substitute for external exposure (IE. D3456) because many other factors, only some of which are listed, can affect these results.

4.2 Familiarity with microbial technology is required. People without at least basic microbiological training should not use this test method.
