The ASTM D3209-93 standard specifies a method for testing the Stability of polymer emulsion floor polishes during repeated freezing and thawing cycles. This method evaluates the performance Stability of floor polishes in low temperature environments by observing emulsion degradation and measuring changes in initial Glossiness. The testing process involves placing the polish sample in a frozen environment and checking the sample for changes in Appearance, Glossiness and transparency after multiple freeze-thaw cycles. This standard is suitable for predicting the Stability of floor polishes when exposed to frozen environments in actual use, providing a scientific basis for product quality control and performance evaluation.
