Introduction to the usage characteristics of the standard group cone calorimeter

Standard Group Cone Calorimeters meet the standards:

ISO 5660, ASTM E 1354, ASTM E 1474, ASTM E 1740, ASTM F 1550, ASTM D 6113, NFPA 264, CAN ULC 135, BS 476 Part 15

Standard Group Cone Calorimeter System Features:

1. Conical heater - in a truncated cone, 230V, 5000W, heat output of 100 kW/m2

2. Apparatus for testing horizontal or vertical samples

3. 3 K class thermoelectric Even and 3-stage PID temperature controller to control the temperature

4. Opening and closing mechanism - to protect the sample area before the test, to ensure the stability of the initial quality measurement, and the operator can have extra time before the test begins System Detection. For flammable samples, if there is no opening and closing mechanism, it is easy to burn prematurely. This extra time is very important for the operator

5. Sample holder - sample size100mm x 100mm, thickness does not exceed 50mm, placed horizontally or vertically

6. Load cell - mass The measurement is tested by the strain gauge load cell and the accuracy can reach 0.01g. Equipped with high-speed electronic weighing components, the mechanical stop device can prevent damage caused by movement, give stable results and ensure long instrument life.

7. Spark ignition - 10kV spark ignition, equipped with safety stop fire device. The igniter is automatically positioned by a lever connected to the closing mechanism

8. Exhaust System - Made of stainless steel for longer life. Includes hood, gas sample needle, exhaust fan (adjustable flow rate, 0 g/s to 50 g/s, with an accuracy of at least 0.1 g/s), and flow tester (thermocouple and differential pressure sensor). Typical test is generally 24 l/s

9. Gas sampling - includes particulate filter, cryogenic coel trap, pump, drying cylinder, flow controller

10. Oxygen Analysis - Sequential Magnetic Oxygen Analyser, between 0-25%, performance to standard

11. Flue gas obscuration - measured with laser system, using photodiode, 0.5 mW HeNe laser, primary and backup photodetectors. At the same time, there are positioning brackets and 0.3, 0.8 neutral density filters for calibration

12. Heat flow meter - used to set the radiation level on the sample surface

13. Burner calibration - Heat dissipation measured by calibrated instrument, using 99.5% pure methane

14. Data Acquisition - Agilent data logger/converter with 3-hole card slot, 6 1/2 digits (22-bit) internal DMM suitable for 120 single-ended measurements or 48 double-ended measurements. Scan speeds up to 250 ch/s with 115k baud RS232 and PCI GPIB interfaces. All measurements are automatically timed and stored in a stable memory for 50,000 measurements

15. Cone Calorimeter Software - Working languages ​​include English, French, German, Spanish and Japanese. The user interface is the Windows operating system with user-friendly button controls, standard Windows data entry methods, drop-down menus, click-to-select, and switches. Able to:

1) display the status of the instrument.

2) Calibrate the instrument and save the calibration results.

3) Collect test data.

4) Calculate the required parameters.

5) Display the results according to the standard requirements.

6) Multiple tests take the average value.

7) Data input to FDMS (Fire Data Management System) - most European and US laboratories apply to this system format, 8. Data exchange of different calorimeters between laboratories.

8) The file output is in CSV (comma-separated file) format, which can be quickly converted into a spreadsheet.
