Audited Supplier ISO 5660 Reaction To Fire Cone Calorimeter to Test Heat Release Rates Fire Testing Equipment
Cone Calorimeter:
Cone calorimeter is one of the most important test instruments for studying the combustion performance of materials.
The cone calorimeter is based on the principle of oxygen consumption, which is used to measure the heat release rate of materials. The so-called oxygen consumption principle is: when the material is burned, the heat released by each unit of oxygen consumed is basically the same, and the measured value is 13.1MJ/kg±5%.

| Structural Features | 1. The cone calorimeter adopts a cabinet design method, and the analysis cabinet can be moved, which can be used not only for the test of the cone calorimeter, but also for the connection of large-scale heat release rate test systems such as single combustion test equipment, solid room fire And cable combustion classification detection, in line with ISO 5660, ASTM E1354, GB/T16172 and other test standards; 2. Integrated test body and 19-inch analysis cabinet, embedded with a PC-type 15-inch industrial touch screen computer, used for the entire control and test process; 3. The rated power of the conical heater is 5000W, and the heat output is 0-100kW/m2. It is controlled by a PID temperature controller, and the radiation cone can be placed horizontally or vertically; 4. The sample box can hold samples up to 100mm x 100mm x 50mm; 5. Sample weighing range 0~2000g; accuracy: 0.1g (different ranges and accuracy can also be provided according to customer requirements); 6. Humidity alarm unit, when the moisture in the sample gas is too high, it can automatically alarm and communicate through the test software; 7. Flow alarm unit, when the smoke and dust in the sample gas are blocked, it can automatically alarm and prompt to replace the filter device. |
| Lgnition System | The ignition system is not less than 10KV high-voltage spark generator, which is automatically positioned by a rotating cylinder. |
| Exhaust System |
The exhaust system is composed of fan, smoke collecting hood, exhaust pipe and orifice flowmeter, etc. The flow rate of the exhaust fan is adjustable from 0 to 50g/s, and the accuracy is 0.1g/s. |
| Gas Sampling System |
1. The annular sampler is installed in the air intake pipe at a distance of 685 mm from the fume collecting hood, and there should be 12 small holes on the sampler to homogenize the gas flow components; 2. The temperature of the airflow is measured by a 1.6 mm diameter closed junction thermocouple, and the thermocouple should be installed 100 mm above the flow measuring orifice; 3. Integrated gas pretreatment system, including sampling pump, filter, condenser, peristaltic pump, moisture filter; condenser temperature: 0~5 degrees, diaphragm pump, flow rate: 3 l/min, pressure: 2.5bar . |
