Equipment Overview
This device simulates the thermal stress test of glowing component or heat source like overload resistance or ignition source which is caused in s short time. It is suitable for electric and electronic products, household appliances and other material to do fire hazard testing. It is also used in the No flame ignition source fire test to test initiation temperature and flammability index of related glowing filament.
1.2 The test equipment adopts to solenoid valve switch to control the burning depth of test sample and equipped with measuring gauge. The test sample will break away automatically from glowing filament after reaching the set time. Also adopting the original imported UK BB K type armour (Ф1mm) whose temperature resistance is up to 1100° (exceed 1050°of standard requirement), this device is with accuracy temperature control.
