Product Specification

ISO 9239 Flooring Radiant Panel Test Apparatus 

Product Introduce

The ISO 9239-1 Flooring Radiant Panel Test Apparatus is a state-of-the-art device designed for evaluating the fire resistance and burning behavior of flooring materials, such as textile carpets, wood flooring, rubber flooring, and plastic coverings. Compliant with international standards like ISO 9239-1, ASTM E648, and GB/T 11785, this advanced testing machine measures critical radiant flux, flame spread, and smoke generation under controlled radiant heat conditions. Ideal for manufacturers, quality control labs, and certification bodies, it ensures compliance with fire safety regulations for building materials, making it an essential tool for ensuring product safety and performance in construction and interior design applications.

Main parameter

1. The stainless steel test chamber features a front-opening door for easy cleaning of the interior walls.
2. The interior walls are constructed of calcium silicate board, providing high-temperature and corrosion resistance.
3. A stainless steel fume hood is installed above the combustion chamber.
4. A 300mm x 450mm porous ceramic heat radiant plate is positioned at a 30-degree angle.
5. A T-shaped porous burner is provided for applying an open flame to the specimen, using a cylinder-driven mechanism.
6. The optical system includes a light source with a 2900 ± 100 K color temperature incandescent lamp, light source is a silicon photodiode;
7. A shutter is installed in front of the silicon photodiode, which can be automatically opened and closed by computer test software for easy calibration;
8. A rotor flowmeter adjusts the flame height of the T-type burner;
9. A propane mass flowmeter adjusts the gas flow to the radiant panel, with digital display;
10. An internal blower provides air source, mixing the test gas via a Venturi mixing system;
11. A mass flow controller adjusts the air flow to the radiant panel;
12. An SB water-cooled heat flow meter has an operating range of 0-50 kW/m², an accuracy of <±2%, and a response time of 0.2 s, providing a portable cooling water source, eliminating the need for external water connections;
13. A user-friendly heat flux meter allows for convenient calibration of the radiant panel's thermal radiation flux, while the test software plots a standard thermal radiation flux curve;
14. A footswitch allows the user to determine the flame spread time to the test distance based on the flame spread distance, which is automatically recorded by the computer;
15. One chimney thermocouple and one chamber thermocouple are installed, both of which are displayed on the computer software;
16. An infrared radiometer is provided to detect the radiant panel temperature, which is also displayed on the computer software;
17. A 15-inch industrial touchscreen computer allows users to monitor the entire combustion test process through the test software;
18. The software displays test-related information such as thermal radiation flux values, smoke density curves, transmittance curves, and wind speed.
