This standard measures the surface Hardness of organic coatings with a SWAT hardness gauge, which is a commonly used nondestructive detection method in the Coatings industry. The test method is used for quick filtering and curing Hardness measurement of coatings, but it should be noted that dimensional differences between different equipment may affect the reproducibility of the results. This standard applies to the measurement of coating Hardness using specified equipment to ensure conformity and accuracy.
