IEC 60331 Wires and Cables Fire resistance testing equipment Shipped to Azerbaijan

Product Introduction:

Designed according to GB/T19216.11-2003 (replacing GB12666.6) and IEC60331-11, this device is used to test the ability of wires and cables to operate continuously under specified conditions under a certain flame source and time. Key components are made of stainless steel, resistant to smoke and gas corrosion. The control system is highly automated, featuring automatic ignition, digital display of temperature and time, convenient observation and recording, and stable and reliable operation. The gas source for the test flame is propane or liquefied petroleum gas. This test apparatus is used for the following measurement conditions: when the flame temperature reaches at least 750°C, testing the circuit integrity of cables exposed to the flame.
