Abstract

There are various methods in designing and manufacturing anti-mold packages. Each different method has its own characteristics that meet the different requirements of different applications. The ASTM standard D3273 governs a method that is easy to follow and operate to test the effectiveness of different anti-mold treatments on packaging materials. With this method, the relative resistance of mold growth on test materials in severe interior environments is evaluated during a four-week period, as well as the comparative resistance of interior coating to accelerated mold growth. These interior environments include conditions of environmental chamber and operation. In this research project, a computerized rating system has been developed to correlate the test results and the veracious molding rate to avoid laboratory errors. Similar to the traditional method, this rating method distinguishes the mold growth pattern based on the image of the test panels which got dried after the tests are done. However, the computerized method is able to evaluate the percentage of a mold area with a k-means clustering algorithm as an automatic rating system that utilizes MATLAB to obtain reliable rating results for various anti-mold tests.
