Audited Supplier ISO 9239-1 Limiting Radiant Chamber for Flooring Materials
Product Description:
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 ISO 9239-1,2 and GB/T 11785-2005 requirements, ISO 9239-1 Limiting Radiant Burning Chamber for Flooring Materials 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 a 30-degree 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

>>> 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 panel (calcium + silicate ) as 13±1 mm of thickness and 650 kg/m3 of nominal density.
3. Air pass dimension between test chamber and test specimen holder is produced by (0.23±0.03) m3 at both beside of specimen fairly.
4. The calorimeter is imported from 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 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 degree per center line bottom.
8. Air velocity of exhaust stack should be attached an exhauster as 2.5±0.2 m/s.
9. It should be used an radiation pyrometer which can be monitor 250mm diameter from about 1.4 meter and has ±5 degree centigrade sod ml accessory with 480ºC to 530ºC (black body temperature) range for adjustment 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 flame length of 60mm to 120mm on Pilot burner flame.
12. It can b adjust limited temperature (900ºC) of backside panel according air flow condition of radiation heat panel.
13. Inlet flow control valve, precise control of propane flow.
