In accordance with fire protection requirements, fire resistance limit tests must be conducted on components such as fire-resistant partition walls, doors, windows, glass panels, and fire shutters. This test furnace simulates the actual temperature rise curve during a fire scenario, meeting the requirements for fire resistance testing of specimens and comprehensively evaluating the fire endurance performance of building components.
According to thermal and structural design specifications, the furnace adopts a metal frame structure with a painted steel outer shell. The furnace chamber and roof are lined with lightweight high-alumina wool and modular zircon fiber blocks. The furnace floor is constructed with modular zircon fiber blocks as well.
Conforms to the following standards:
GB 9978-2008: Fire resistance test methods for building components
GB/T 38252
GB 16809
GB 12955
GB/T 7633
GB/T 23449
GB/T 23450
GB/T 23451
In accordance with GB 9978, the furnace temperature rise must follow the formula:
T – T₀ = 345 × log(8t + 1)
Where:
t = elapsed test time (minutes)
T = furnace temperature at time t (°C)
T₀ = initial furnace temperature (5°C–40°C)
At 3 meters height inside the furnace and 100 mm from the surface of the test specimen:
At 5 minutes into the test: Furnace pressure should be 15 Pa ± 5 Pa
At 10 minutes into the test: Furnace pressure should be 17 Pa ± 3 Pa
Loss of integrity
Loss of insulation: Occurs if the average temperature on the unexposed surface of the specimen rises more than 140°C above its initial average temperature, or if any single point on the unexposed surface rises more than 180°C above its initial temperature
Internal Furnace Dimensions: 3.0 m × 3.0 m × 1.2 m
Overall Equipment Dimensions: 8000 × 6000 × 7000 mm (net height 5500 mm)
Fuel Type: Natural gas or liquefied petroleum gas (LPG)
Maximum Operating Temperature: 1300°C
Number of Burners: 8
Specimen Installation Method: External mounting
Combustion Control System: Proportional combustion, automatic furnace pressure control, automatic temperature adjustment, programmable temperature curve control, computer-aided management
