ISO 9239 Flooring Radiant Panel Test Apparatus for Critical Radiant Flux
Introduction:
Critical Radiant Flux is the main parameter of the fire risk for flooring materials, it reflects the burning and spreading ability of flooring material specimens under external heat radiation conditions. It is an important index of combustion classification for building products.
According to ISO9239-1,2 and GB/T 11785-2005 requirements, Flooring Radiant Panel Test Apparatus is measuring the critical radiant of combustion floor coverings, through the radiation environment of the test chamber. It can also be used to measure the critical radiation of the cellulose insulation floor material.
The specimen is located at the down horizon of 30 degrees sloped gas radiation panel per horizon surface.
Pilot flame as an ignition resource put a part edge of the specimen on the high-temperature side.
This equipment record ignition time by spark, and moving time by which flames horizontally pass by a specimen of length.
Application:
1. Building Materials
2. Rail
3. Automotive Interior
4. Other

Main Features:
1. All structural components are made of stainless steel, beautiful appearance, and corrosion resistance.
2. The test chamber is made of the panel (calcium + silicate ) 13±1 mm in thickness and 650 kg/m3 of nominal density.
3. Air pass dimension between the test chamber and test specimen holder is produced by (0.23±0.03) m3 at both beside of the specimen fairly.
4. The calorimeter is imported from the United States, range of 50kW/m2.
5. Radiant chamber had a stop of 30±1degree per horizon panel and can be resisted up to 900-degree centigrade. It also should include a safety-blocking function.
6. The radiation source is a porous ceramic heat radiating plate of 300mm*450mm and tilted 30 °.
7. The pilot burner should be stationed equally as 0.7mm diameter and 19/EA, producing a slop of 60 degrees per center line bottom.
8. The air velocity of the exhaust stack should be attached to an exhauster as 2.5±0.2 m/s.
9. It should be used a radiation pyrometer which can be monitored 250mm diameter from about 1.4 meters and has ±5 degree centigrade sod ml accessory with 480ºC to 530ºC (black body temperature) range for adjustment of the surface quality of heat of radiant panel.
10. It can be measured that flow within tolerance from radiant heat panel to 110mm to 910mm at 100mm intervals.
11. It can be adjusted flame length of 60mm to 120mm on the Pilot burner flame.
12. It can b adjust the limited temperature (900ºC) of the back side panel according to the airflow condition of the radiation heat panel.
13. Inlet flow control valve, precise control of propane flow.
