BS 476 ASTM E1354 ISO 5660 Cone Calorimeter Testing Device Cone Calorimetry Tester
1.Overview:
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 fire environment.
2. Meet the standard
• 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.
3.Measurement System
3.1,Paramagnetic oxygen analyzer, the range is 0-25%; linear response; oxygen sensor.
3.2,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.
3.3,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. 3.4,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.
3.5,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.
