3 Terminologies and Definitions
Terminologies and definitions stipulated in GB/T 5823-1986 and GB/T 5907-1986 as well as the following terminologies and definitions are applicable in this standard.
3.1 Fire resistant side hung door sets
This is formed by door wing, fireproofing hinge and fireproofing lock. Hinge is the shaft perpendicular to the floor, this shaft can rotate clockwise or counterclockwise to open or shut the fire resistant door sets of the door wing.
3.2 Fire resistant timber door sets
Use the flame resisting timber, flame resisting timberwork to make the doorframe, door wing frame, door wing panel and filling material within the door wing, then fill the fireproofing heat insulating material that is harmless for the human, then form the door with the fire resisting property by assembling with the hardware fittings.
3.3 Fire resistant steel door sets
Use the steel material to make the doorframe, door wing frame, door wing panel and fill material within the door wing, then fill the fireproofing heat insulating material that is harmless for the human, then form the door with the fire resisting property by assembling with the hardware fittings.
3.4 Fire resistant timber door sets with steel structure
Use the steel material, flame resisting woodiness material or flame resisting timberwork to fabricate the doorframe, door wing frame, door wing panel and filling material within the door wing, then fill the fireproofing heat insulating material that is harmless for the human, then form the door with the fire resisting property by assembling with the hardware fittings.
3.5 Other material fire resistant door sets
Use the inorganic noncombustible material, steel, flame resisting timber and flame resisting timberwork but not the steel material, flame resisting wood or flame resisting timberwork to fabricate the doorframe, door wing frame, door wing panel and filling material, then fill the fireproofing heat insulating material that is harmless for the human, then form the door with fire resisting property by assembling the hardware fittings.
3.6 Fully insulated door sets
Within the time specified, this door set can meet the requirements for fireproof integrality and ablative insulating quality.
3.7 Partially insulated door sets
Within 0.50 h greater than or equal to the requirement, fireproof integrality and ablative insulating quality requirement can be met; when 0.50 h is exceeded, fireproof integrality requirement of the fire resistant door sets can also be met.
3.8 No insulated door sets
Within the time specified, the door set can meet the requirements for fireproof integrality and ablative insulating quality.
