This standard specifies a method for testing whether coatings are sufficiently drying under standard conditions to resist surface damage when stacked. It is mainly used to evaluate the tolerance of single-layer or multi-layer coatings after a specified drying period, on two coating surfaces or when coatings come into contact with Miscellaneous surfaces. Testing simulates the actual conditions under which coated items are stacked on top of each other to ensure that coatings are not damaged by contact pressure during handling or transportation. This method helps to test the abrasion resistance performance of coatings in actual use, ensuring the suitability of coatings after drying.
