Heat release quantity is the core parameters to evalate the fire
behavior of materials and products.TESTech's Cone Calorimeter can
meet all existing standards (including ISO 5660, ASTM E 1354, ASTM
E 1474, ASTM E 1740, ASTM F 1550, ASTM D 6113,NFPA 264,CAN ULC 135
and BS 476 Part 15).This equipment includes these systems such as
heat release, mass loss, smoke generation, etc,and allow users to
buy the parts they need one by one and add into the same
chamber.This flexible feature is one of it's advantages.
Cone Calorimeter test theory is based on the principle that the
burn calories is proportional to the amount of oxygen's
consumption,1KG oxygen consumption will produce 13.1 MJ heat. Test
gas heat emission, ignition timing, oxygen consumption rate, CO/CO2
generation rate, the gas flow will be measured all. Cone
Calorimeter DAQ system can help users to easily control the entire
test. 19 "touch screen can help realizing the automatic testing and
reducing installation space. In addition, users can also change the
sample temperature, or adjust the temperature rise time to
test,after setting up the virtual temperature at real fire
conditions. This method can obtain the similar test results to real
ISO 5660: Reaction to fire tests - the rate of heat release, smoke
generation rate and mass loss rate.
ASTM E 1354: Standard Test Method of materials heat and visible
smoke release rate.
BS 476 Pt.15: Building materials and structures test: - Test method
for heat release rate of products.
1.1,19-inch standard cabinet of integrated design, elegant, and
easy to operate.
1.2,Conical Heater of 230V, 5000W, the heat output of 0 ~ 120 kW /
1.3,19-inch touch-screen computer controlling the entire testing
1.4,Automatic ignition system,and automatic burning time
1.5,3 pieces K-thermocouples and 3 PID temperature controllers for
1.6,Split gate -To protect samples area before the test, and insure
the initial measurement stability.The operator could have extra
time to detect before the test start. If there is no opening
closing mechanism, the flammable samples are easy to burn too
early. So this extra time is very important for the operator.
1.7,The sample holder -The sample size is 100mm x 100mm, and
thickness is not exceed 50mm;The central portion of the sample
about 50mm*50mm is exposed to the heating cone center and deviation
1.8,Weighting system -quality is measured by the strain gauge load
cell test, accuracy up to 0.1g. Equipped with swift electronic
weighing parts,mechanical stop fixture can avoid moving damage, to
ensure the equipment longevity.Weighing range is 0 ~ 3kg.
2.1,Equipped with 10kV spark ignition,as well as safety cease-fire
devices. The igniter can automatic location by connecting to the
close mechanism lever.
2.2,Automatic ignition,timing;expiration, and turn off the fire.
3.1,Exhaust systems is consisted of axial fan, stainless steel
exhaust pipe,diffusion plate, exhaust fume collecting hoods,
exhaust pipes, orifice flow meter and a thermometer.
3.2,All the fixture is made of stainless steel to prolong their
life.Including the hoods, the gas sample sampling needle, exhaust
fan (adjustable flow, 0g/s to 50g/s, the accuracy at least of
0.1g/s), and the orifice flow tester (thermocouple and differential
pressure sensors). The common Work flow is 24 g/s.
