Cone Calorimeter TCC 918 ISO 5660-1, ASTM E1354 Method and Instrumentation Analyzing & Testing

For Fire Testing and Fire Safety Engineering The cone calorimeter is considered the most significant instrument in fire testing. This is because the net heat of combustion is proportional to the amount of oxygen required for combustion. The specimens are irradiated, ignited by sparks and thereby combusted. This apparatus analyzes the combustion gases and measures the smoke produced from a test specimen that is being exposed to a certain heat flux. The principle is known as the “oxygen consumption principle” and is among the methods of calorimetry. From the oxygen concentration, the released heat...

Principle of Operation The specimen (100 × 100 × 50 mm3) is positioned onto a sample holder that is placed in the load cell. The load cell monitors the sample mass during the measurement. Depending on the specimen, the sample holder can have open or closed edges. Igniter and Cone Heater A spark igniter is located between the specimen’s surface and the cone heater. This ignites the flammable gases evolving from the specimen when it is heated. If the entire specimen area is burning, the igniter is turned off. A conical radiant electrical heater uniformly irradiates the specimen from above. Once...

Efficient Peltier Cooling Device for Gases The sampling gas is cooled by one controlled Peltier cooler, which can be set down to -10°C. This eliminates any need for the expensive thermostat for gas cooling and/or drying agent which are commonly used. Ethernet for Control Automation Technology – EtherCAT The NETZSCH Taurus TCC 918 is designed with the latest in hardware technology, including a new EtherCAT technique for communication between the different devices. It clearly improves reaction times between all electronic components and allows for real time data acquisition as well as excellent...

Continuous Gas Analyzer for the HRR Calculation The use of optical couplers and optical filters in IR physics leads to an increase in selectivity. This ensures the ability to measure at low concentrations and low detection limits. To this end, the system is equipped with the robust Siemens ULTRAMAT/ OXYMAT 6E, featuring corrosionresistant materials in the gas channel. It serves for the detection of two infrared components, CO and CO2, as well as O2 in accordance with the standards. OXYMAT The only analyzer needed to perform fundamental cone calorimeter experiments is the oxygen analyzer. Additional...

Mass Flow Controller Especially for Methane The methane gas burner comes with a piezoelectric igniter. A mass-flow controller (MFC) especially for methane includes a magnetic valve and shut-off valve, both for methane. The performance is also adjusted to the requirements of the calibration burner. The burner is protected by a stainless-steel cover. Sample Holder The sample holder is made of stainless steel and has a holding frame and CaSi panels. It is horizontally open for easy sample loading. Depending on the specimen, sample holders with open or closed edges are available. In some cases, a...

Influence of Flame Retardants on the Fire Behavior of Electric Components Flame retardants (FR) in plastic materials ensure their fire safety. The type and quantity depend on the application and the requirements of the flammability standards. Small amounts are desirable to have the least effect on the plastic’s properties and processing behavior. Since a small fire can already develop dense smoke to make visual orientation difficult or even obstruct the escape of a trapped person or the smoke can be toxic to the fire victims, special non-halogenated flame retardants and graphite based flame retardants...
