GB/T 24573-2009 stipulates the fire resistance performance test method of vault and archive doors. The standard specifies the test equipment, such as the requirements for heating devices that can simulate the high temperature of a fire, and clarifies the test process, including the installation and fixation of the door, heating according to a specific temperature. Linear dispersion heating, continuous observation of the integrity and insulation of the door at different times. The fire resistance performance of vault and archive doors is extremely critical, which is related to the safety of valuables and important materials. According to this standard test, the fire resistance of the door can be accurately evaluated, the product mass can be ensured, and it can be effectively protected in a fire, reducing the risk of property loss and information damage.
