GB/T 1740-2007 specifies a test method for evaluating the resistance of paint films to combined heat and humidity conditions, simulating accelerated aging in tropical or humid environments. It is applied in the coatings industry for quality control and product development, particularly for paints used on automotive, construction, and industrial equipment surfaces. The standard defines procedures for exposing coated panels to controlled temperature and humidity cycles, then assessing degradation such as blistering, rusting, or adhesion loss.
