Equipment Overview
Samples and Restrictions: Electrical devices, their components and parts, solid insulating
substances, and other solid flammable materials.
Application: This device replicates the thermal stress caused by glowing
elements or heat sources, such as overload resistance or ignition
points, within a brief period. It is suitable for assessing the
fire risk of electrical and electronic devices, household
appliances, and other materials. Furthermore, it is used in
non-flame ignition source fire tests to determine the ignition
temperature and combustibility index of related glowing filaments.
Test Principle: The glowing filament, made of the required material and shape
(Ni80/Cr20), is heated to the testing temperature range of 550°C to
960°C for 1 minute using a high-current glow wire tester. The test
sample is then vertically exposed to a pressure of 0.95N for 30
seconds. By observing whether the test sample or surrounding
materials ignite, or the duration of the burn, users can assess the
ignition risk of electrical and electronic products. This device is
used for ignition tests, ignition temperature (GWIT) tests,
flammability tests, and flammability index (GWFI) tests of solid
insulating materials and other solid combustible substances.
Structure: The device features advanced PLC control and a 7-inch color touch
screen. It is equipped with a solenoid valve to control the burning
depth of the test sample and a measuring gauge, ensuring precise
and rapid operation. The test sample will automatically detach from
the glowing filament once the set time is reached. Using the
original imported UK BB K-type thermocouple (1mm), which has a
temperature resistance of up to 1100°C (surpassing the 1050°C
standard requirement), this device offers highly accurate
temperature control.
