Fire door refers to a door that can meet the requirements of fire stability, integrity and heat insulation within a certain period of time. In addition to the function of ordinary doors, fire doors have the function of preventing the spread of fire and smoke, which can prevent the spread of fire within a certain period of time and ensure the evacuation of people. It is generally installed in fire partitions, evacuation stairwells, vertical shafts and other fire partitions with certain fire resistance.
Fire doors must pass mandatory CE certification when they are exported to the European Union. The CE certification standard for fire doors is EN1634-1. Normally, EN 1634-1 is used in conjunction with EN 1363 fire resistance test standards. Let's take a look at the CE certification EN1634-1 standard for fire doors.
CE certification standards for fire doors:
EN 1634-1: Fire and smoke control tests for doors, roller shutters, and openable windows and building hardware. Part 1: Fireproof doors, roller shutters, and openable windows
BS 476-20: Fire test of building materials and structures. Part 20: Method for determining the fire resistance of building components (general principles)
BS 476-21: Fire test of building materials and structures. Part 21: Method for determination of fire resistance of load-bearing members
BS 476-22: Fire test of building materials and structures-Part 22: Method for determination of fire resistance of non-load-bearing components
BS 476-23: Fire Tests of Building Materials and Structures Part 23: Method for determining the contribution of components to the fire resistance of structures
ASTM E 119 Standard Test Method for Fire Test of Building Structures and Materials
EN 1363-1: Fire test-Part 1: General requirements.
EN 1364-1: Fire test of non-load bearing components-Part 1: Walls.
EN 1364-2: Fire test of non-load bearing components-Part 2: Ceilings.
EN1634-1 standard test range:
1. Hinge doors and revolving doors;
2. Horizontal sliding doors and vertical sliding doors, including hinged sliding doors and lifting sliding doors;
3. Single-layer steel sheet folding shutters (not insulated);
4. Horizontal sliding and vertical sliding doors, including hinged sliding doors, sectional doors, and sectional doors;
5. Tilt the door;
6. Rolling shutter doors.
7. Single-layer folding door;
8. Other sliding hinged doors.
Fire door CE certification EN1634-1 fire resistance test performance evaluation:
1. Loss of integrity: When the cotton pad is ignited or the back side burns for more than 10 seconds, it is considered that the test piece has lost its integrity; during the test, a 6mm diameter probe can penetrate the crack and enter the furnace and probe The rod can be no less than 150mm along the length of the crack; when a probe with a diameter of 25mm can pass through the crack and enter the furnace, it is considered that the test piece has lost its integrity.
2. Loss of thermal insulation: If the uniform temperature rise of the back surface of the specimen exceeds the initial uniform temperature of 140℃, or the temperature rise of the back surface at any point exceeds the initial temperature of 180℃, the specimen is considered to be lost Thermal insulation.
3. Loss of load-bearing capacity: The test piece collapses during the experiment; or when the maximum deflection of the beam and plate members, the axial deformation of the column member, and the axial deformation rate of the column member exceed the specified value, it is considered that the test piece has lost the load-bearing capacity .
