GB/T 9266-2009 "Determination of scrubbing resistance of architectural coatings coatings" standard specifies the method used to evaluate the scrubbing resistance of architectural coatings planar coatings. This standard applies to all kinds of architectural coatings that can be made into planar coatings, including the use of specific scrubbing resistance test instruments and scrubbing media to determine the durability of coatings. The standard describes in detail the instruments and materials required for testing, including the formulation of scrubbing media. Test results are assessed according to whether the coating is damaged, providing a benchmark for quality control of architectural coatings.
