Glow Wire Tester GW-1
Standard:IEC60695-2-10, IEC60695-2-13 and UL746A.
Application:This device simulates the thermal stress test of glowing component
or heat source like overload resistance or ignition source which is
caused in a 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.
Test sample:Electrical equipment and its components and parts, solid electrical
insulating materials and other solid combustible materials.

Feature: Test principle: the glowing filament whose material and shape is
required(Ni77/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.
