GB/T 13480 - 2014 specifies the method for measuring the compression performance of thermal insulation products for buildings. It specifies the test principle, that is, applying pressure to thermal insulation products and measuring deformation. Standard Specifies test equipment, such as press accuracy requirements. Detailed description of sample preparation, including size, quantity and state adjustment. During testing, specify the loading rate, pressure range and other operational details. Calculate compression strength, compression resilience modulus and other indicators by recording pressure and deformation data. The standard provides a basis for evaluating the performance of thermal insulation products under pressure, and helps construction projects to select products that can withstand the corresponding pressure and maintain the thermal insulation effect to ensure the stable operation of building thermal insulation systems.
