The Vertical Fire Resistance Test Furnace for Building Elements is designed for fire resistance testing of vertical building components, including non-loadbearing vertical partitions, fire doors, and fire shutters. The furnace is manufactured in accordance with the technical requirements of GB/T 9978. integrating the furnace body, furnace roof, steel test platform, exhaust and air supply system, combustion and gas supply system, and a comprehensive test control system.With built-in calibration capability, the system ensures that furnace temperature, pressure values, and distribution meet standard requirements, making it suitable for standardized fire resistance testing and performance evaluation of vertical building elements.
Standards
The equipment complies with the following standards:
(1) GB/T 9978.4-2008 – Fire Resistance Tests — Elements of Building Construction — Part 4: Specific Requirements for Loadbearing Vertical Separating Elements
(2) GB/T 9978.8-2008 – Fire Resistance Tests — Elements of Building Construction — Part 8: Specific Requirements for Non-loadbearing Vertical Separating Elements
(3) GB/T 7633-2008 – Fire Resistance Test Methods for Doors and Shutters
(4) ISO 834 – Fire Resistance Tests — Elements of Building Construction
(5) EN 1363 – Fire Resistance Tests for Building Elements
Features
Stable Furnace Structure
Frame-type furnace body with refractory bricks and high-temperature insulation fiber ensures thermal stability while minimizing heat loss to the surrounding environment.
Safe and Practical Platform Design
Steel platforms are installed around the furnace to facilitate operator movement and on-site inspection.
Automatic Flame-Out Protection
If a burner extinguishes unexpectedly, the control system immediately triggers visual and audible alarms and automatically cuts off the LPG supply to the affected burner while allowing other burners to operate normally.
Comprehensive Gas Supply Control
Equipped with gas solenoid valves, proportional valves, ball valves, and gas transmitters to ensure accurate gas flow control and operational safety.
Optimized Combustion Air Control
Combustion air is supplied by a dedicated blower with frequency control to maintain an appropriate air–fuel ratio.
Independent Control System
Dedicated control components are used to manage combustion processes and accurately simulate standard fire curves.
Automatic Temperature Curve Correction
The actual furnace temperature curve is continuously compared with the preset curve, and deviations are automatically corrected through burner output adjustment.
Complete Data Storage
All automatic control and test data are stored in the computer system for traceability and accuracy verification.
