This standard provides a set of standardized test methods for evaluating the resistance to heat and humidity of carbon fiber-reinforced resin matrix composites under no applied stress. It specifies in detail the test principles, required equipment, sample preparation, condition settings, operational procedures, result calculations, performance classification, and the final test report format. The standard is applicable for evaluating such composites that may experience moisture absorption, plasticization, or interface performance degradation in hot and humid environments. To meet the test conditions that may involve accelerated moisture absorption and high-low temperature cycles as outlined in the standard, key testing instruments such as high-low temperature humidity test chambers are typically used.
