Critical Radiant Flux Flammability Testing Equipment For Flooring Panel
Application
It is used to measure the burning of materials through a certain degree of heat radiation and flame environment. It is used in various kinds of floor materials such as textile carpet, cork board, wood board, rubber board, plastic floor and floor coating material Case of the critical heat radiation value. The EU uses this test method to classify fire protection material for all European Union member countries.
Features
1. All structural components are made of stainless steel, appearance,and corrosion resistance;
2. The radiation source is a porous ceramic heat radiating plate of 300mm*450mm, and tilted 30 °;
3. The calorimeter is imported from United States , range 50kW/m2;
4. The igniters diameter is 0.7mm, 19/EA, is located at the bottom of the center line of each 60°;
5. The standard plate is made of calcium silicate without coating layer,which is size of 1050*250mm and thickness is 20±1mm ,density is 850 ± 100kg/m³;
6. Small stainless steel auxiliary ignition burner ignited sample.
7. Inlet flow control valve, precise control of propane flow;
8. Equipped with air blower providing air, mixed gas through the venturi mixing gas
