Building Materials Flammability Tester Radiant Flooring Panel
Apparatus
Application
Critical Radiant Flux is the main parameters of the fire risk for
flooring materials, it reflects the burning and spreading ability
of flooring material specimen 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, ISO
9239-1 Flooring Materials Radiant Analyzer with Good Price is
measuring the critical radiant of combustion floor coverings,
through the radiation environment of test chamber. It is can also
be used to measure the critical radiation of the cellulose
insulation floor material. Specimen is located at down horizon of
30 degree sloped gas radiation panel per horizon surface.
Features
1. Blower for gas supply of radiant plate can supply gas
continuously, while air compressor supply gas uncontinuously.
2. Heat Flux meter, portable water cooling system without running
water supply.
3. Ventilation hood of stainless steel on the top of the chamber.
4. Inner chamber of Heat and corrosion resistant Aluminum silicate
plate.
5. Heat resistant honeycomb ceramic thermal radiant plate
300mmX450mm, inclined at 30 degree.
6. T-shape porous burner with auto ignition system ignites the
specimen with automatic push system.
7. Gas control board. Needle valve control the height of burner
flame, MFC controls the gas flux and digital display.
8. Inverter control blower output, ventruri control the proportion
of air and gas, and flame is stable, and accurate.
9. porous calibration apparatus: adjust radiant plate output by
turning upward, left or right.
10. IR radiometer shows the temperature of the radiant plate.
11. Optional smoke density testing system.
12. Optical system 2900 ± 100 K light advanced optical signal
receiver.
13. integrated design with 19" PC of Lab view software.
14. Chimney with1pc thermocouple, and 1pc thermocouple inner
Chamber controlled by software.
