GB/T 7633-2008 standard specifies the fire resistance test method of doors and roller shutters. It specifies the equipment, process and conditions of the test, covering key links such as heating system and loading method. By simulating fire scenarios, doors and roller shutters are tested from dimensions such as integrity, thermal insulation, and load-bearing capacity. The standard provides a basis for manufacturers to control the mass of products and the construction industry to screen qualified fire protection products. It is of great significance to ensure that doors and roller shutters effectively play the role of fire separation and prevention of fire spread in fires.
