GB/T 30806-2014 《Thermal insulating products for building applications—Determination of dimensional stability under specified temperature and humidity conditions》 Related products

GB/T 30806 - 2014 Specifies Dimensional Stability Testing of Thermal Insulation Products for Buildings. It specifies that the test is carried out under specific temperature and Humidity conditions to simulate the actual use environment. The standard requires test equipment, such as a test chamber with controlled temperature and Humidity, and details the sample preparation process, including size measurement and initial recording. During the test, the temperature Humidity change procedure and duration are strictly stipulated, and the sample size is measured regularly. The dimensional Stability of thermal insulation products is evaluated by comparing the size data before and after. The standard provides a basis for judging whether the product can maintain its shape in a complex environment, helping to ensure the long-term stable operation of the building thermal insulation system and ensure the thermal insulation effect.
