quantity is the core parameters to evalate the fire behavior of materials and products.TESTechs 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 its advantages.
Cone Calorimeter test theory is based on the principle that the burn calories is proportional to the amount of oxygens 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.
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.
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.
. The igniter can automatic location by connecting to the close mechanism lever.
2.2,Automatic ignition,timing;expiration, and turn off the fire.
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.
