Products

Heat release quantity is the core parametersto evalatethe fire behavior of materials and products.TESTech'sCone Calorimeter canmeet 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'sadvantages.

Cone Calorimeter test theory is based onthe principle that the burn calories is proportional to the amount of oxygen's consumption,1KGoxygen consumption will produce 13.1 MJ heat.Test gas heat emission, ignition timing, oxygen consumption rate, CO/CO2generation 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 automatictesting and reducing installation space. In addition, users can alsochangethe sample temperature, or adjust the temperature rise time to test,after settingup the virtual temperature at real fire conditions. This method can obtain thesimilar test resultsto real fire environment.

Standards

• ISO 5660: Reaction to fire tests - the rate of heat release, smoke generation rate and mass loss rate.

Structural features

19-inch standard cabinetof integrated design, elegant, and easy to operate.

Conical Heater of 230V, 5000W, the heat output of 0 ~ 120 kW / m2.

19-inch touch-screen computer controlling the entire testing process.

Automatic ignition system,and automatic burning time calculation.

3 pieces K-thermocouples and 3 PID temperature controllers for temperature regulation.

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.

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 is ±1%.

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.

Measurement

Paramagnetic oxygen analyzer, the range is 0-25%; linear response

With a laser system to measure the smoke density, using a photodiode, 0.5 mW helium-neon laser, primary and backup photodetectors. Also equipped with the positioning bracket and 0.3.0.8 neutral density filter used for calibration.

High-precision load sensor measures the weight changes of the test material during test process.The test range is 0~3000g, and resolution ratio is 0.01g. The required test sample weight is less than 500g.

Temperature control system: PID temperature control, 3 dia1mm thermocouples to measure temperature of the radiation cone, In addition with a 1 mm armoured thermocouple measuring the temperature 100mm above the orifice plate.

Exhaust flow: This data is caculated by the differential pressure of the sharp edge holes on both sides of the exhaust pipe,which inner dia is 57mm±1mm,and cooperate with micro differential pressure transmitter.Located at 350mm above fan transducer,the pressure transmitter is connected to the control system,so as to automatic control of wind speed.
