ASTM E1354 Cone Calorimeter Building Materials Laboratory Fire Test Equipment

Introduction:

The structural principle of the cone calorimeter, the combustion analysis system structure consists of the following parts: combustion chamber, exhaust and flow test system, gas sampling and analysis system, flue gas test system, ash mass sampling system, data acquisition and control system, and oxygen concentration control system. The cone calorimeter mainly follows ISO5660 and ASTME1354 standards, and can complete the test of the following parameters under various oxygen mole fraction conditions: ① heat release rate of materials, kW/m2; ② mass loss rate, kg/sm2; ③ sample ignition time, s; ④ CO, CO2 generation rate, kg/kg; ⑤ specific extinction area, m2/kg; ⑥ ash mass sampling, kg/kg; ⑦ effective combustion heat, mJ/kg.

Application of the cone calorimeter

1. Evaluation of combustion performance of materials Combining HRR, pkHRR and TTI, we can quantitatively determine the combustion hazard of materials, including analysis of combustion performance of indoor decoration materials, combustion characteristics of combustible materials in coal mines and characteristics of smoke from mine fires, analysis of fire hazards of packaging materials, crops, small commodities, wires and cables, etc.

2. Evaluation of the performance of flame retardant materials

3. Conduct fire modeling research

Main Feature:

1. The cone calorimeter adopts a cabinet design, and the analysis cabinet is movable. It can be used for cone calorimeter testing and can also be connected to large heat release rate test systems such as single combustion test devices, 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 PC-type 15-inch industrial touch screen computer, used for the entire control and test process.

3. The cone heater has a rated power of 5000W, a heat output of 0-100kW/m2, and is controlled by a PID temperature controller. 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 accuracies can also be provided according to customer requirements).

6. The ignition system is a high-voltage spark generator of no less than 10KV, which is automatically positioned by a rotating cylinder.

7. Paramagnetic oxygen analyzer, range 0-25%, response time: 4 seconds, linear deviation: ≤0.5% FS, repeatability: ≤50 ppm O2, sensitivity drift: ≤ 0.1 vol.% O2/week or ≤ 1% measurement value/week (non-cumulative), whichever is smaller, detection limit: ≤50 ppm O2.

8. Non-dispersive infrared CO and CO2 analyzer CO: 0~1%; CO2: 0~10%, measurement principle: infrared absorption, response time: 2.5 seconds, linear deviation: ≤1% FS, repeatability: ≤0.5% FS, zero drift: ≤1% FS/week, detection limit: ≤0.5% FS.

9. The smoke density analysis uses a laser system to measure the smoke density. The system consists of a photodiode, a helium-neon laser, a main detector and an auxiliary detector.

10. The exhaust system consists of a fan, a smoke hood, an exhaust duct, and an orifice flowmeter. The exhaust fan flow is adjustable from 0 to 50 g/s with an accuracy of 0.1 g/s.

11. The annular sampler is installed in the air intake duct 685 mm away from the smoke hood. There should be 12 small holes on the sampler to homogenize the air flow components.

12. The temperature of the air flow is measured by a Kai-clad thermocouple with a closed node of 1.6 mm in diameter. The thermocouple should be installed 100 mm above the flow measurement orifice.

13. The SB type heat flow meter is selected, with a design range of 0~100k W/m and an accuracy of ±3%, repeatability is ±0.5%, with a calibration report attached.

14. The data acquisition system can automatically record the output of gas analyzers, orifice flow, thermocouples, and other instruments.

15. Equipped with software operating system, the test results include: heat release rate, flue gas flow rate, C coefficient, sample ignition time and extinguishing time, total oxygen consumption, total smoke generation, mass loss rate, total heat release, effective combustion heat, carbon dioxide generation and carbon monoxide generation.
