The ASTM D4213-24 standard test method is used to determine the scrub resistance of coatings, particularly for indoor coatings. This method measures the weight loss of coatings during the scruf process by using a standard calibrated panel to evaluate their relative resistance to scruf. The test results provide quantitative data on the scruf resistance of coatings to help evaluate the actual use performance of coatings. This method is particularly effective for comparing the scrub resistance of different coatings, but does not directly reflect the ease of cleaning.
