Product Description

 

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/CO2all. 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 fire environment.

Model Standards:

.

• 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.

Main Features 

1,Structure

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 / m2.

1.4,Automatic ignition system,and automatic burning time calculation.

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.

1.8,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,Ignition Systems

. The igniter can automatic location by connecting to the close mechanism lever.

2.2,Automatic ignition,timing;expiration, and turn off the fire.

3,Exhaust systems

xhaust 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.

4,Gas sampling system

Gas sampling system includes an annular sampler probe, suction pump, particulate filter, a cold trap, exhaust valve, water filters and CO24.2,Three filters; Minimum filtration accuracy is 0.5um.

4.3,Freezing cold trap; air-conditioning compressor refrigeration systems; controlling the temperature in 0 ~ 5℃.

4.5,Drying cylinder,which filter the water and impurities.

4.7,The sampler has 12 holes and gas flow in the opposite direction;these holds built-in dust filter and 685mm from hoods.

5,Measurement System

ed oxygen sensor.

5.2,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.

5.4,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.

6,Calibration Systems

quipped with water cooling system to protecting the security of heat flow meter. - Design range is 0~100k W / m², the accuracy of heat flow meter is Â±3%, repeatability is Â±0.5%.

6.3,Equipped with a water cooling system for heat flow meter.

7,Operating systems

7.2,PC via RS485 interface communication module and PLC communication link for data transmission and motion control;

7.4,Signal acquisition and processing module connected with the air volume control module circuit, output by a programmable logic controller,Intelligent adjust the preset speed.Mechanical rotating module links PLC I/O port, to control the closure of rotary.
