Cone Calorimeter.pdf Instrument introduction The cone calorimeter is derived from the oxygen consumption of a
rectangular sample (100mm×10mm) tested by Dr. Vytenis Babrauskas at
a heat radiation value of 100KW/m2. The cone calorimeter is based on the principle of oxygen
consumption of material combustion. The heat released per 1Kg of
oxygen is about 13.1MJ. It measures the heat release of the
material, ignition time, oxygen consumption, CO and CO2 production,
and the flow of combustion gas. The cone calorimeter strictly conforms to the size of the
laboratory, and the automatic control unit designed by the test
software is convenient for the user to operate. In addition, he
uses a 17-inch touch screen computer, which is fully compliant with
international standards.

Product Features and Application 1.Cone Calorimeter with movable analysis cabinet, can be connected
with a large heat release rate test system such as ISO 9705, EN
13823 etc, complied with ISO 5660, ASTM E1354,BS 476 Part 15 etc.
testing standards. 2.Integrated test body and 19 inches analysis cabinet, embedded PC
15 Inch Touch screen computer, for the whole control and automatic
testing. 3.Conical heater rated power 5000W, the heat output of 0 ~
100kW/m2, using PID temperature controller, while the radiation
cone can be horizontal or vertical. 4.Exposed to the central part of the surface of the sample 50 x
50mm range, radiation at the center of the deviation is not more
than 2%. 5.The sample weighing range 0 ~ 3000g; accuracy: 0.1g. 6.Auto Split Shutter automatically opened to transmit radiation to
the sample. 7.ABB EL3020 Paramagnetic oxygen analyzer, using the method of
paramagnetic change to measure the concentration of oxygen in the
gas. Concentration range of 0-25%. 8.Smoke density analysis using laser system, the system consists of
a 0.5mW He Ne laser, the main detector and auxiliary detector. The exhaust system consists of the fan, the smoke collection cover,
the exhaust pipe and orifice plate flow meter and so on. Exhaust
fan flow rate of 0 ~ 50g/s, precision 0.1g/s. 9.Ring sampler have been installed from the smoke collecting hood
at 685 mm, with 12 holes. 10.The exhaust flow rate should be determined by measuring the
pressure difference on both sides of the sharp edge orifice 350 mm
above the fan, the inner diameter of the sharp edge orifice plate is 57mm + 1mm. 11.ABB SCC-S Gas sampling system comprises sampling pump, filter,
cold trap, waste water discharge, water filters and CO2 filters; Portable water cooling system without need for waterworks and
plumbing when using the Heat Flux meter (for ISO 5660). 12.In order to calibrate the response of the whole test system, the
use of a square opening brass calibration burner, used to measure
the value of C- coefficient. 13.The data acquisition system be able to record oxygen analyzer,
orifice meter, thermocouple and other instruments of the output. Application: Suitable for testing the heat release rate of building
materials, Rail,Wire Cable
Product Details of the Cone Calorimeter The name of Cone Calorimeter is derived from the conical heater as
used by Dr. Vytenis Babrauskas to inspect test specimen (100mm x
100mm) with flux up to 100kW/m2 for the bench scale oxygen
depletion of his development. Cone Calorimeter test is based on the
theory that pure combustion calories are in proportion to a
necessary amount of oxygen for combustion and 13.1 MJ/kg is
generated whenever oxygen 1kg is consumed, and heat emission,
ignition time, oxygen consumption, CO and CO2 generation, and flow
of ignited gases as generated from test materials are measured. Standards ASTM:ASTM D6113,ASTM E1354,ASTM E1740,ASTM F1550 BS:BS 476-15 ISO:ISO 5660 EN:EN 45545-2: 2013 GB:GB/T 16172:2007
Installation Requirements Electrical: 230 volts Nominal 50 Amps Ambient Temperature: Operating 10°C to 35°C Dimensions: Apparatus: 1800mm (W) x 900mm x (H) x 2600mm (D) Gas Supplies:Methane, Nitrogen, Compressed Air

Cone Calorimeter. The Cone is a fire testing tool based on the
principle that the amount of heat released from a burning sample is
directly related to the amount of oxygen consumed during the
combustion. The amount of heat a material generates is directly
aligned with the severity of a fire, such as fire growth rate.
