GB/T 33011-2016 specifies the method for the determination of the anti-freeze-thaw performance of thermal insulation products for buildings. It specifies the requirements for test equipment, such as test chambers that can simulate a freeze-thaw environment. Detailed instructions for placing thermal insulation specimens under specific freeze-thaw cycle conditions, specifying parameters such as freezing, melting temperature and duration. The anti-freeze-thaw performance of the specimen is determined by observing the changes in the appearance, size and performance of the specimen after multiple freeze-thaw cycles. The standard provides a basis for evaluating the durability of thermal insulation products under complex climate conditions in cold regions, ensuring that they can still effectively exert thermal insulation effect under long-term freeze-thaw action, and ensure building energy conservation and structural safety.
