ASTM D3210-95 (2023) is a standard test method for comparing the Color of thin films of water emulsion floor polishes. This method compares Color by measuring the luminescence reflectance of thin films (or solids) formed by the deposition of emulsification particles, using a tri-stimulus colorimeter (such as Hunter color difference meter) for detection. This method is suitable for evaluating the Color of thin films formed by floor polishes after drying, providing a scientific basis for product quality control and performance evaluation. Through this standard, the conformity of different batches or brands of water emulsion floor polishes on Color can be ensured to meet the user's requirements for product Appearance.
