What is a Fire Door？
A fire door is an essential component of fire safety, designed to prevent the spread of fire to other areas. It provides a critical barrier, buying valuable time for the evacuation of occupants and emergency personnel.
A fire door is a door with a fire resistance rating.
Fire doors are used to reduce the spread of fire and prevent smoke from traveling between areas.
Fire doors are an essential part of any building, as they can slow the spread of fire between rooms. In the event of a fire, they may be able to save your life or the lives of others.
A common misconception is that steel doors are automatically fire doors, but this is not true. Fire doors must undergo fire resistance testing to determine their fire resistance rating.
CNS11227-1 Fire resistance tests
A complete fire door assembly, including the door frame, door leaf or sliding door, hardware accessories, and seals, is designed to meet the requirements for fire resistance, flame containment, or heat insulation. According to the CNS11227-1 fire resistance performance testing method, the fire door is tested for fire, smoke, and heat containment performance, and its fire resistance rating is determined.
Reference Standard: NFPA 80
Any combination of fire door leaf, door frame, hardware, and other accessories that provides a certain level of fire protection performance for the openings in a building.
Reference Standard: UK Building Regulations - Approved Document
A door or gate installed within a building, along with its frame and accessories, designed to resist the passage of flames and combustion gases, and meet specific performance criteria.
What is a Fire Door?
Fire doors are rated for heat resistance and are used to reduce the spread of fire and smoke. They are a crucial component of buildings, designed to protect the lives of occupants by preventing the fire from spreading between different areas.
Fire door frames and their hardware components, tested in accordance with CNS11227-1 regulations, can sustain their fire resistance for the specified duration during heating tests.
Fire Rating
Fire door frames and their assembled components are able to continuously maintain fire resistance properties, including flame-shielding, stability, and heat insulation, during testing.
Fire Resistance
In fire resistance testing, the fire door frame assembly and components, when exposed to fire on one side, can prevent the penetration of flames and hot gases for a specified period of time, while also ensuring that flames do not appear on the non-heated side.
Fire Integrity
The fire door frame and component accessories, when subjected to fire resistance testing, must maintain structural stability for a specified period, whether under load-bearing conditions or not, to prevent collapse.
Fire Stability
Under fire resistance test conditions, the building fire door frame components and structures must have the ability to ensure that, when one side is exposed to fire, the temperature on the unexposed side does not exceed the specified limit within a certain period of time.
Fire Insulation
The fire resistance heating test ensures that the fire door frame components and accessories have the ability to prevent smoke or fumes from passing from one side to the other through the non-exposed side during the specified test duration.

Fire Door Performance
Fire Resistance Rating Label（CNS）
Fire rating
Fire doors are specifically designed to withstand flames for a specified duration. The duration for which they pass testing determines their fire resistance rating or fire endurance.
The fire resistance ratings of fire doors are categorized by fire endurance as follows: 30/60/120/180/240 minutes.
All certified fire doors must have compliant labels installed on both the door and the door frame.
Insulation
Has a fire resistance rating of 60 minutes and a heat insulation performance of 60 minutes.
f(60A)
Has a fire resistance rating of 60 minutes but only a heat insulation performance of 30 minutes.
f(60/30A)
Has a fire resistance rating of 120 minutes but only a heat insulation performance of 60 minutes.
f(120/60A)
Fire Resistance Rating Label（CNS）
Fire rating
Fire doors are designed to withstand flames for a specified period of time, with fire resistance ratings classified as 30, 60, 120, 180, and 240 minutes.
在特定測試條件下，材料、構件、構造等能持續維持耐火性所經過之時間
f(60A)
材料、構件、構造等能持續維持遮焰性、穩定性及阻熱性之耐火性能
