The cone calorimeter is a fire testing device that measures heat release and oxygen consumption during combustion to assess material flammability. It utilizes an external heat source and a conical design to determine key combustion characteristics like ignition time and heat release rates. The system includes various advanced components such as temperature controllers, gas sampling tools, and data acquisition software for comprehensive fire testing.

1. Cone Calorimeter
A cone calorimeter is a fire test tool that is based on the amount of heat released during
the combustion process directly related to the oxygen consumption in the combustion
process. The amount of heat generated is directly proportional to the severity of the fire,
such as the rate of fire growth. In order to obtain the flammability of the material, this is
exposed to an external radiation heat source. Therefore, since this is a forced combustion
test, the cone value is generally considered to reflect the second ignitability of the ignition.
Standard：
ISO5660,ASTM E 1354, ASTM E 1474, ASTM E 1740, ASTM F 1550, ASTM D 6113, NF
PA 264, CAN ULC 135, BS 476
Scope of application:
The Cone Calorimeter is the most significant bench scale instrument in the field of fire
testing.
Principle:
A sample is placed in a "cone" shaped radiant heater. Normally, the sample is exposed to
35 kW / m2 of external flux-forming heaters. However, for more refractories the heater is
often increased to 50 kW / m2. Once sufficient pyrolysis products are produced, ignition
occurs. Combustion products pass through a conical heater and through an instrument
discharge tube. The measured / calculated values are usually important including, but not
limited to, the maximum ignition time, the mass loss rate during combustion, the maximum
amount of time and heat released during combustion, the total amount released during the
test Heat
complete system includes:
1. Conical heater - in a truncated cone, 230V, 5000W, with a heat output of 100 kW / m2
2. Test the sample device in horizontal or vertical.
3. 3 K-type thermocouple and 3 PID temperature controllers for temperature regulation
4. Opening and closing mechanism - to protect the sample area before testing to ensure
that the initial quality measurement is stable, the operator can have additional time to test
the system before testing. For flammable samples, if there is no opening and closing
mechanism, it is easy to burn prematurely. This extra time is very important to the operator
5. Sample holder - sample size 100mm x 100mm, thickness of not more than 50mm,
placed horizontally or vertically
6. Load cell - quality measurement by strain gage component test, the accuracy of up to
0.01g. Equipped with quick electronic weighing components, mechanical stop device can
avoid damage caused by movement, given the stable results, to ensure that equipment
longevity
7. Spark ignition - 10kV spark igniter, equipped with a safety cease-fire device. The igniter
is automatically positioned by means of a lever connected to the closing mechanism
8. Exhaust system - made of stainless steel to extend life. (Flow rate adjustable from 0 g /
s to 50 g / s with an accuracy of at least 0.1 g / s), and orifice flow testers (thermocouples
and differential pressure transducers), including hoods, gas sample sockets and exhaust
fans. Common tests are typically 24 l / s

2. 9. Gas sampling - including particulate filter, freezing cold trap, pump, drying cylinder, flow
controller
10. Oxygen analysis - paramagnetic oxygen analyzer, 0-25%, standard performance
11. Smoke fog - measured with a laser system using a photodiode, 0.5 mW helium-neon
laser, primary and standby photodetectors. With positioning bracket and 0.3,0.8 neutral
density filter for calibration
12. Heat flow meter - used to set the level of radiation on the sample surface
13. The burner calibration-calibration apparatus tested the heat release rate by using 99.5%
pure methane
14. DATAACQUISITION - An Agilent wheel data collector / converter with 3-hole card slot,
6 1/2 digit (22 bit) internal DMM for 120 single-ended measurements or 48 double-ended
measurements. Scan rate up to 250 channels / s with 115k baud RS232 and PCI GPIB
interface. All readings are recorded automatically, with a stable reading of 50000 in the
memory
15. Cone Calorimeter Software - Operating languages include English, French, German,
Spanish and Japanese. The user interface is a Windows operating system with
easy-to-use button operations, standard Windows data entry, drop-down options,
click-to-select, and switch
Feature:
1). Displays the instrument status.
2). Calibrate the instrument and store the calibration results.
3). Collect the test data.
4). Calculate the required parameters.
5) Display the results by the standard way.
6). Multiple tests are averaged.
7). Data entry to FDMS (Fire Data Management System) - Most European and US
laboratories apply the system format, sharing data between different laboratory
calorimeters.
8). the file output is in CSV (Comma Separated File) format, which can be quickly
converted to a spreadsheet
Optional Configuration：
1, Carbon dioxide and carbon monoxide - available NDIR gas analyzer.
2, Hydrogen chloride - heating supply lines and gas analyzers.
3, Controlled gas accessories - for low-oxygen sample analysis.
4, the quality of the loss of calorimeter.
5, FTIR toxicity tester.
6, the protection of doors - to protect the operator does not inhale poisonous samples
generated by the flue gas. Normal air can enter from the bottom for normal test zone
exhaust and test zone air intake. The steel plate blocks the rear, the exhaust hood blocks
the top, and the test door blocks the bottom, protecting the door against the last side.
