GB/T 4893.7-2013 is used to test the ability of furniture surface coatings to withstand rapid temperature changes. The sample is first placed in a high-temperature environment (e.g., 60°C) for a period of time, then quickly transferred to a low-temperature environment (e.g., -20°C), and this cycle is repeated several times. After the test, the coating surface is inspected for damage such as cracks, blistering, wrinkling, or loss of gloss. This method aims to simulate usage environments with significant temperature differences (e.g., near heating equipment) and evaluate the internal stress stability and interlayer adhesion of the coating.
