Mold resistance test
Mold resistance testing is an examination that investigates the resistance of various industrial products and materials to mold (the difficulty of mold growth). It allows for the confirmation of the effectiveness of preservative treatments on industrial products and materials. A similar test is the mold occurrence confirmation test.

basic information
Necessary information for conducting the test It would be smooth if you could provide the following information: - Desired testing method and testing standards - Number of samples (types) - Properties of the samples (material, dimensions, etc.) - Preferred test fungi (if you wish to use a different strain than the standard) *If you are unsure about the choice of testing method, please let us know the background for conducting the test and the properties of the samples.
Price information
It varies depending on the testing method, type and number of samples, so please contact us.
Delivery Time
※(In many cases) approximately 6 to 7 weeks. *This varies depending on the testing method. Most of the testing period consists of the pre-culturing of the test mold and the culturing period of the main test.
Applications/Examples of results
【Testing Method】 Each test fungus is pre-cultured (for about 1 to 3 weeks) to prepare a mixed spore suspension. The mixed spore suspension is inoculated onto the sample (test piece) and cultured in an environment conducive to fungal growth (e.g., 26±2°C, relative humidity 95-99%) for 1 to 4 weeks. Afterward, the growth of the fungus is observed both visually and under a microscope to determine the degree of fungal development. *Basically, it is not possible to distinguish the degree of development of each test fungus contained in the mixed spore suspension. The assessment is made based on the overall degree of development of all test fungi present in the mixed spore suspension.
