Product Overview

Core Product Advantages

1. Standardized High-Power Radiant Heating Panel
   Equipped 450×300mm porous ceramic radiant plate, maximum surface temperature up to 750℃ with peak radiation intensity reaching 62kW/m². The heat flux distribution gradient strictly follows standard requirements: starting from 50kW/m² near the ignition end and gradually dropping to 1.5kW/m² at the far end of the specimen, accurately reproducing uneven thermal radiation conditions in actual fire scenes. Observation grids spaced at 50mm intervals are pre-installed on the sample rack for intuitive flame front position recording.
2. Stable Propane Ignition Flame System
   Independent calibrated propane pilot burner delivers fixed 80mm flame length; the nozzle is arranged 20mm away from the specimen’s heated edge to achieve consistent ignition effect for every test. Equipped precision gas flow control components to stabilize gas mixing ratio, avoiding flame fluctuation caused by air pressure changes during long-term batch testing.
3. Full Safety Gas Anti-Backflow Protection
   Multi-layer gas safety interlock structure including check valves, automatic cut-off solenoid valves and overheat protection sensors. Once reverse flame backflow or radiant plate overheating is detected, the system instantly cuts off propane supply to eliminate fire hazards. Optional full explosion-proof gas pipeline assembly is available for high-risk laboratory environments.
4. Intelligent Integrated Test Control System
   Touch operation terminal pre-stores complete ISO and IMO standard test programs, supporting 0–10 hours unattended automatic testing. Built-in high-definition video recording module synchronously captures the whole flame spreading process; all test data including flame advance time, heat flux and cumulative heat release can be stored and printed as standardized inspection reports with one click.
5. Split Modular Frame & Easy Maintenance
   Separate control cabinet, radiant heating frame and waste liquid collecting tray design. All contact components in the combustion chamber are made of corrosion-resistant stainless steel, easy to wipe off soot and molten residues after testing. The sliding sample platform enables fast loading and unloading of vertical test panels without dismounting the radiant assembly.
6. Complete Heat Release Detection Matching
   The exhaust flue is fitted with multi-point thermopile temperature sensors, which cooperate with the control system to automatically calculate total heat release and peak heat release rate of materials, realizing one machine to complete flame spread test and thermal output evaluation simultaneously, reducing laboratory equipment investment.

Standard Complete Test Operation Steps

1. Pre-Equipment Calibration & Inspection
   Power on the control system, start the radiant plate preheating program, use matching heat flux meter to calibrate surface radiation intensity; check gas pipeline tightness and anti-backflow safety valve working status, connect video recording equipment.
2. Specimen Fixed Mounting
   Install the vertical test panel on the stainless steel sliding support frame, lock the positioning bolts to ensure the specimen surface is parallel to the radiant plate, push the rack into the standard test station and close the test baffle.
3. Gas & Test Program Setup
   Open the propane gas supply valve, set test duration and data recording frequency on the touch panel, select ISO building material mode or IMO marine material dedicated program according to inspection requirements.
4. Automatic Ignition & Flame Spread Test
   The radiant plate stabilizes to the set temperature gradient, the pilot burner automatically extends to ignite the specimen edge. The system continuously records the time required for the flame front to pass each 50mm grid and synchronously captures video footage.
5. Post-Test Data Derivation
   After the test timing ends, the gas circuit automatically cuts off; the touch screen calculates flame propagation speed, ignition heat, critical heat flux and total heat release, and supports one-click export of complete test records and video files.
6. Equipment Cleaning & Shutdown
   Wait for the radiant plate to fully cool down, pull out the sample rack to remove residues, wipe soot on the radiation panel and flue thermocouple, close gas and power supply to finish the testing workflow.
