DX8383 Glow Wire Tester
Glow wire test is to test the stability of electronic and electrical products during operation. The glow wire itself is actually a resistance wire ring with a fixed specification. During the test, it needs to be electrically heated to the specified temperature to make the top of the glow wire contact the sample for the standard time, and then observe and measure its state. The test range depends on the specific test procedure.
Glow wire tester is applicable to electrical equipment and its components and parts, as well as solid electrical Insulating material Or other solid combustible materials, in accordance with GB/T5169.10~13 、 IEC60695-2-1/0~2-1/3 、 GB2099 、 VDE 0620 、 GB4706 、 UL817 Test standard requirements.

Corresponding test method of glow wire burning tester:
Glow wire flammability test method for finished products (IEC 60695-2-11:2000/GB/T 5169.11-2006)
Glow wire flammability test method of materials (IEC 60695-2-12:2000/GB/T 5169.12:2006)
Glow wire ignitability test method of materials (IEC 60695-2-13:2000/GB/T 5169.13-2006)
Flammability index GWFI
GWFI —— glow-wire flammability index
The higher test temperature of a test sample of specified thickness in three consecutive tests shall meet one of the following conditions:
a) After removing the glow wire The flame or burning heat of the test sample goes out within 30 seconds, and the wrapping silk paper placed under the test sample does not ignite;
b) The test sample did not ignite.
Ignition temperature GWIT
GWIT —— glow-wire ignition temperature
The temperature is 25K higher than "the higher temperature at the top of the glow wire that will not ignite the test sample of the specified thickness after three consecutive tests (30K higher between 900 ℃ and 960 ℃)".
