Highlights
Fire Testing System for measuring the heat release and smoke production during flame spread tests on vertically mounted bunched cables and insulated wires, in accordance with EN 50399 and IEC 60332-3-10 (testing device)
The KBT 916 from NETZSCH TAURUS Instruments GmbH is easy to operate, offering innovative control and data acquisition options in an intuitive format with ample user guidance.
The high-resolution color touch display on the “KBT Control” cabinet allows for measuring and control with the integrated Single Board Computer, Windows operating system and KBT software. There is thus no longer any need for manual controls such as switches, controllers or buttons; the status of the testing system is clearly displayed and the system prevents any critical operating errors. The storage, analysis and recording of all test data is handled entirely via the control unit. Well thought-out details along with the use of high-quality materials guarantee the KBT 916 test system a long product life and a low degree of wear and tear.

Method
Test Method
The cable is exposed to the flames in a closed chamber for 20 minutes. The cables are mounted in a vertical tube furnace on a ladder and the flame is ignited with a propane gas ribbon burner. The time of ignition provides information for evaluating the combustion behaviour.
Test Setup
The cables to be tested are evenly distributed on the conductor. During the fire test, the conductor with the cable samples facing inwards is placed vertically against a wall in a combustion chamber. The burner is placed in front of the conductor at a distance of 7.5 cm from the samples.
Measurement
The spread of the flame and the burning droplets/particles are observed and the length of the fire damage is measured at the end of the test. The flue gases produced during combustion are discharged via an exhaust air duct, where the speed of the air flow, theO2 andCO2 content as well as the light absorption and temperature are measured.
