According to ISO 9239-1,2 and GB/T 11785-2005, the flooring radiant panel test measures the critical radiant flux of floor coverings under burning conditions in a test chamber and within a specified thermal radiation environment.

It can also be used to measure the critical radiant flux of cellulose insulation materials for attic floors.

When a building fire occurs, flames may spread through a compartment or adjacent room, or hot gases may spread over the floor surface, causing radiant heat to accumulate during the early stage of fire growth.

Under these conditions, the apparatus can effectively reflect flame spread behaviour of flooring materials in counterflow ventilation conditions.

• All structural components are made of stainless steel for attractive appearance and corrosion resistance.
• The test chamber is made of board material (calcium plus silicate), thickness 13 +/- 1 mm, with nominal density of 650 kg/m3.
• The volume of circulating gas between the test chamber and the specimen is generated evenly from both sides of the specimen, and the circulation area is (0.23 +/- 0.03) m2.
• The radiant heat source is a gas-fired panel inclined at 30 degrees and directed toward a horizontally placed flooring sample. The radiant panel produces radiant energy flux from 10.9 kW/m2 to 1.1 kW/m2, can reach 900 degrees C, and includes a safety shut-off function.
• Imported heat flux meter from the United States, range 20 kW/m2.
• The pilot burner diameter is 0.7 mm, 19/EA, located at 60 degrees from the bottom of each centre line.
• Maximum radiant panel temperature: 900 degrees C.
• The standard board is made of uncoated calcium silicate board with thickness 20 +/- 1 mm, density 850 +/- 100 kg/m3, and size 1050 x 250 mm.
• A small stainless steel ignition burner assists specimen ignition. Igniter inner diameter 6 mm, outer diameter 10 mm; two rows of holes, one row with 19 holes of 0.7 mm diameter and one row with 16 holes of 0.7 mm diameter.
• A flow control valve is provided for precise control of propane flow at 0.026 +/- 0.002 L/s.
• The tempered values and repeated configuration items are retained as provided in the original product content.

• The exhaust duct shall be equipped with an exhaust device of 2.5 +/- 0.2 m/s.
• Exhaust capacity: 85 m3/min.
• The exhaust air speed meter has accuracy of +/- 0.1 m/s and is located 250 +/- 10 mm above the lower edge of the chamber flue.

• Radiation pyrometer accuracy: +/- 0.5 degrees C, located about 1.4 m from the radiant panel.
• Radiation pyrometer sensitivity remains constant within the wavelength range of 1 um to 9 um.
• High-performance K-type sheathed thermocouple, diameter 3.2 mm, with insulated and ungrounded hot junction, positioned 25 mm below the chamber top plate and 100 mm behind the inner wall of the chamber flue.
• Heat flux meter range: 0 to 15 kW/m2; accuracy: +/- 2%.
• A radiation pyrometer capable of detecting a diameter range of 250 mm and blackbody temperature range of 480 to 530 degrees C should be used to adjust the heat flux on the surface of the radiant panel within the allowable error range, measuring heat flux from 110 mm to 910 mm from the heat dissipation plate at intervals of 110 mm.
• Angle control plate is provided for convenient observation and control during setting and calibration stages.
• Stainless steel hood with smoke test probe.
• Data collection and analysis software.
• The flame length adjustment range of the ignition burner is 60 to 120 mm.
• According to the airflow condition of the radiant panel, the critical temperature of the rear panel can be adjusted to 900 degrees C.
• Smoke density system included.

• Standard control cabinet with computer and Labview intelligent control system.
• Control parameter setting and display; test status and fault display and query.
• Data acquisition and storage; screen monitoring, real-time temperature curve, historical curves and data query.
• USB data export; historical curves and data query; printing.
• The machine can be independently operated to complete the test.
• Audible alarm and alarm event display functions.
• USB/RS232 serial port on the control cabinet for external desktop or laptop operation and free printing of test reports.
• Programmable logic controller (PLC) control system.
• Automatic ignition and ignition failure detection protection.
• Automatic control and display of propane gas flow.
• PLC plus inverter provides automatic control and display of exhaust gas flow.

• The critical heat flux (CHF) kW/m2 corresponding to flame spread length can be observed through thermal flow linear velocity testing.
• If the specimen test time exceeds 30 minutes, the extinguishing time and the fastest flame spread rate can be recorded and then converted into critical heat flux.
