Test Procedures
Mount the test sample on the sample rack at the top of the tunnel furnace.
Start the tunnel furnace; flames are emitted from the dual-head nozzle onto the sample.
Conduct the test for 10 minutes, recording flame spread and smoke development.
Calculate the Flame Spread Index (FSI) based on flame propagation distance and time.
Measure the Smoke Developed Index (SDI) and classify the material according to ASTM E84 standards.
Maintenance Information
Regularly clean the flame nozzles and furnace to remove carbon deposits for uniform flame distribution.
Calibrate smoke collection devices and sensors quarterly to ensure accurate measurements.
Keep sample fixtures and supports intact to prevent deformation affecting results.
Turn off power and ventilate the lab after use to prevent smoke residue from damaging equipment.
