The mold growth test is the final test of a new product being tested under conditions that are very favorable for mold growth. Testing can detect the nature of any failure in a product with good design performance. To sum up, the mold growth test is to identify the degree of mold growth of samples and their materials under climatic conditions conducive to mold growth and the surface changes and performance effects caused by mold growth. The alternating mold test chamber is a special device that allows test samples to be placed in an ideal climate environment suitable for the rapid growth of mold spores to artificially assess the anti-mold performance of test samples and their structural materials, and the impact of mold growth on the electrical and mechanical properties of test samples. Test equipment.
