GB/T 23983-2009 "Determination of Yellowing Resistance of Wood Coatings" specifies the method for determining the yellowing resistance of wood coating films and is applicable to various types of wood coating products. The test involves placing coating film samples in a UV aging chamber or natural exposure environment and periodically measuring the degree of yellowing using a colorimeter. The detection requires instruments such as a UV aging test chamber, colorimeter, and standard whiteboard, providing a standardized testing method for evaluating the yellowing resistance of wood coatings.
