GB/T 33001 - 2016 specifies the method for measuring the bending performance of thermal insulation products for buildings. It specifies the preparation of the sample in detail to ensure that it can represent the actual product. Clarify the accuracy and specifications of the test equipment, and standardize the loading method and rate. Strict requirements for the temperature and Humidity of the test environment to ensure accurate data. Through this standard, the bending performance of thermal insulation products can be accurately determined, providing reliable data for the selection of building design materials, helping to improve the Stability and energy saving effect of building structures, which is of great significance to the construction industry to ensure the mass engineering.
