GB/T 30804 - 2014 specifies the method for measuring the tensile strength of thermal insulation products for buildings perpendicular to the surface. It specifies the test principle, that is, applying a tensile force perpendicular to the surface of the product until it is damaged. Standard specification test equipment, such as Tensile machine accuracy requirements. Detailed description of sample preparation, including preparation rules, size measurement. During testing, specify the loading rate, fixture requirements and other operating details. Calculate the tensile strength perpendicular to the surface by recording the tensile force value at the time of damage. The standard provides a basis for evaluating the ability of thermal insulation products to resist vertical tension, and helps construction projects to select products with good tensile performance to ensure that the thermal insulation layer is firmly installed and the stable operation of the building thermal insulation system is guaranteed.
