ActiveDetermination of the long-term change in thermal resistance of closed-cell plastics(accelerated laboratory test methods)
闭孔塑料长期热阻变化的测定 实验室加速测试方法
Application Summary AI generated
This standard specifies accelerated laboratory test methods for determining the long-term change in thermal resistance of closed-cell plastics, such as rigid polyurethane foam. It is primarily applied in the construction industry for evaluating the durability of thermal insulation materials used in building envelopes, including roofs, walls, and floors. The standard is used by manufacturers and testing laboratories to predict insulation performance over time under simulated aging conditions.
