It's compatible with tests such as single-burning devices, solid room fire tests, and cable combustion classification, adhering to standards like ISO 5660, ASTM E1354, and GB/T16172.

• Integrated Control Unit: Includes a 19-inch analysis cabinet equipped with a 15-inch industrial touchscreen computer, providing PC-based control and real-time monitoring throughout the testing process.

• High-Performance Cone Heater: The cone heater delivers a rated power of 5000W, with a heat output range of 0-100 kW/m². It features a PID temperature controller and offers flexible placement of the radiation cone, either horizontally or vertically.

• Versatile Sample Holder: Accommodates samples up to 100mm x 100mm x 50mm. The weighing system supports a range of 0-2000g with 0.1g accuracy. Custom ranges and accuracies are available to meet specific customer needs.

• Advanced Ignition System: Equipped with a high-voltage spark generator (minimum 10KV) and a rotating cylinder for precise automatic positioning.

• Accurate Oxygen Analysis: Utilizes a paramagnetic oxygen analyzer with a 0-25% range, 4-second response time, and exceptional linearity, repeatability, and sensitivity specifications.

• Precision CO and CO2 Analysis: Non-dispersive infrared analyzers measure CO (0-1%) and CO2 (0-10%), featuring rapid 2.5-second response time, high accuracy, and low drift.

• Laser-Based Smoke Density Analysis: Smoke density is analyzed using a helium-neon laser system with a photodiode, main detector, and auxiliary detector.

• Comprehensive Exhaust System: Comprises an exhaust fan, smoke hood, exhaust duct, and orifice flowmeter. The exhaust fan operates within a 0-50g/s range with 0.1g/s accuracy. An annular sampler, positioned 685mm from the smoke hood, ensures homogenized gas flow for accurate measurement.

• Integrated Gas Pretreatment: Includes a sampling pump, filter, condenser (0-5°C range), peristaltic pump, and moisture filter, all working to condition the sample gas for precise analysis.

• Humidity and Flow Alarms: The system alerts operators when moisture levels in the sample gas are too high or when flow is obstructed by smoke particles, signaling the need for filter replacement.

• SB-Type Heat Flux Meter: Measures heat flux with a range of 0-100 kW/m², offering ±3% accuracy and ±0.5% repeatability, complete with a calibration report.

• Self-Contained Water Cooling System: Eliminates the need for an external water source by integrating a portable cooling system, particularly useful when utilizing the heat flux meter.

• Methane Calibration Burner: Used to calibrate the entire system, ensuring accurate C-factor value measurement.

• Comprehensive Data Acquisition: Automatically records outputs from gas analyzers, thermocouples, orifice flow, and other instruments, with results displayed via user-friendly software. The system provides detailed reports on heat release rate, flue gas velocity, sample ignition and extinction times, total oxygen consumption, smoke production, mass loss rate, total heat release, effective combustion heat, and the generation of carbon dioxide and carbon monoxide.

Cone Calorimeter

Cone calorimeter, developed by V. Babrauskas and colleagues at the National Institute of Standards and Technology (NIST) in the United States in 1982, is a testing instrument for evaluating the combustion performance of materials based on the principle of oxygen consumption.

Over the past 30 years, the cone calorimeter has undergone continuous improvement and refinement, becoming one of the most important testing instruments for studying the combustion performance of materials.

The cone calorimeter is based on the principle of oxygen consumption and measures the heat release rate of materials. According to the principle of oxygen consumption, the heat released per unit of consumed oxygen during material combustion is essentially the same and is measured to be 13.1 MJ/kg ± 5%.

In the experiment, the sample can be loaded on the specimen holder, and the mass loss rate of the sample during combustion can be measured. By heating the sample and igniting it through an electric spark, the flammability and ignition time can be tested.

The combustion gases are collected in the attached ducts and exhaust hood, and parameters such as heat release rate are automatically measured by monitoring changes in smoke pressure difference, gas concentration, and temperature.

Optical devices can be used to measure smoke density performance parameters. Additionally, by obtaining the above data, further derived data such as effective combustion heat and specific extinction area can be calculated. Cone calorimeter testing is a safe, fast, and accurate method of detection. In addition to product development, the cone calorimeter can also be used as a quality control tool.
