Equipment Overview
Samples and Restrictions: Electrical equipment and its components and parts, solid electrical insulating materials and other solid combustible materials, etc.
Application: 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 non-flame ignition source fire test to determine initiation temperature and flammability index of related glowing filament.
Test Principle: The glowing filament whose material and shape is required(Ni80/Cr20) is heated to the testing temperature of 550 ℃ ～ 960 ℃ for 1 min by using the glow wire tester with large current. Then using required pressure (0.95N) vertically burns the test sample for 30s. By observing whether the test sample and bedding object ignite or the burning time, the users can judge the ignition danger of electric and electronic products. It is used for the ignition test, ignition temperature (GWIT) test, flammability test and flammability index (GWFI) test of solid insulating material and other solid combustible material.
Structure: Adopting advanced PLC control, and 7inch color touch screen, it is with solenoid valve switch to control the burning depth of test sample and equipped with measuring gauge, this device has the features of exact and rapid. The test sample will break away automatically from glowing filament after reaching the set time. Adopting the original imported UK BB K type thermocouple(1mm)whose temperature resistance is up to 1100°(exceed 1050°of standard requirement) , this device is with accuracy temperature control.
