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 essential index of combustion classification for building products.
According to ISO9239-1,2 and GB/T 11785-2005 requirements, ISO 9239 Radiant Panel Test Apparatus Flammability Testing Equipment For Flooring Materials measuring the critical radiant of combustion floor coverings, through the radiation environment of a test chamber. It can also be used to measure the critical radiation of the cellulose insulation floor material.
The specimen is located at a 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.
ISO 9239 Radiant Panel Test Apparatus Flammability Testing Equipment For Flooring Materials record ignition time by spark, moving time which flame horizontal pass by the specimen of length.
Application:
1. Building Materials
2. Rail
3. Automotive Interior
4. Other
Standard:
>>> ISO 9239-1: Reaction to Fire Tests for Flooring- Part 1: Determination of Burning Behavior Using a Radiant Source;
>>> ISO 9239-2: Reaction to Fire Tests for Flooring- Part 2: Determination of Flame Spread at a Hat Flux Level of 25kW/m2;
>>> ASTM E 648: Standard Test Method for Critical Radiant Flux of Floor- Covering System Using a Radiant Heat Energy Source;
>>> ASTM E 970: Standard Test Method for Critical Radiant Flux of Exposed at Attic Flooring Insulation Using a Radiant Heat Energy Source;
>>> NFP A 253: Standard Method of Test for Critical Radiant Flux of Floor Covering System Using a Radiant Heat Energy Source (National Fire Code. Vol.6);
>>> KS F ISO 9239- 1: Reaction to Fire Tests for Flooring- Part 1: Determination of Burning Behavior Using a Radiant Source;
>>> KS F ISO 9239-2: Reaction to Fire Tests for Flooring- Part 2: Determination of Flame Spread at a Hat Flux Level of 25kW/m2;
Main Features:
1. All structural components are made of stainless steel, beautiful appearance, and corrosion resistance.
2. Test chamber is made of the panel (calcium + silicate ) as 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 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 be include a safety-blocking function.
6. The radiation source is a porous ceramic heat radiating plate of 300mm*450mm, and tilted 30 °.
7. Pilot burner should be stationed equally as 0.7mm diameter and 19/EA produced a slop of 60 degrees per center line bottom.
8. Air velocity of the exhaust stack should be attached to an exhauster as 2.5±0.2 m/s.
9. It should be used as a radiation pyrometer that can monitor 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 hat flow within tolerance from radiant heat panel to 110mm to 910mm at 100mm intervals.
11. It can be adjusting the flame length from 60mm to 120mm on the Pilot burner flame.
12. It can b adjust the limited temperature (900ºC) of the backside panel according to the airflow condition of the radiation heat panel.
13. Inlet flows control valve, precise control of propane flow.
