The GB/T 1741-2020 standard specifies the method for determining the mold resistance of paint films, including the test principle, required instrumentation and equipment, foster bases and reagents used, specific test procedures, and requirements for reporting results. The standard is suitable for evaluating the resistance of architectural coatings to mold, and can also be used as a reference for the mold resistance test of Miscellaneous types of paint films. A number of normative documents are quoted in the standard, such as the condition adjustment of Coating samples, artificial climate aging exposure conditions, etc., to ensure the accuracy and repeatability of the test. The definition of mold resistance includes the ability of paint films to resist or inhibit the growth of mold spores and mycelium. It is one of the important indicators for evaluating Coating performance.
