You need to know if electrical parts can handle heat and not catch fire. The glow wire test helps you check this. When you use this test, you see how materials react to high temperatures. This is important because many electrical faults start with heat. If a wire gets too hot, it can cause a fire. You want to make sure the materials in your products do not burn easily.
-
The glow wire test checks the flame resistance of materials.
-
It simulates high temperatures that could cause fire hazards.
-
You can see if materials can handle short bursts of heat and stop or slow down burning.

Sample Preparation
You must get your samples ready before the test. Cut the material to the right size and shape as the standard says. Make sure the surface is clean and has no dust or oil. Put the sample in the holder so it does not move during the test. This helps you get clear and correct results.
Always follow safety rules when using hot tools and samples. Wear gloves and safety glasses to protect yourself. Good preparation and careful setup make your glow wire test safe and successful.
Glow Wire Test Procedure
Preparing the Sample
You start by getting your sample ready. Cut the material to the size that the test standard asks for. Make sure the edges are smooth and the surface is clean. Remove any dust, oil, or dirt. Place the sample in the holder so it stays still during the test. If the sample moves, you may not get the right results.
Tip: Always wear gloves and safety glasses when you handle the sample. Hot tools and sharp edges can hurt you.
Setting Up the Tester
Next, you set up the Kingpo KP-FT01 Glow Wire Tester. Turn on the machine and check that the touchscreen works. Select the test type you want to run. You can choose from glow wire ignition temperature (GWIT), glow wire flammability index (GWFI), or the basic glow wire test. Make sure the K-type thermocouple is clean and connected. This sensor checks the wire’s temperature. Set the wire to the right starting temperature for your test.
-
Check the ventilation in the room.
-
Make sure the tester is on a stable table.
-
Review the safety features before you begin.
Heating and Application
Now you heat the wire. The tester brings the wire to the temperature you set. The temperature depends on the test type. Here is a table that shows common settings:
|
Test Type |
Starting Temperature |
Increment/Decrement |
Final Condition |
|---|---|---|---|
|
GWIT |
500°C |
+50°C |
Sustained combustion observed |
|
GWFI |
960°C |
-50°C |
Specimen self-extinguished |
You wait until the wire reaches the right heat. The tester will tell you when it is ready. Then, you move the hot wire to touch the sample for a set time, usually 30 seconds. Watch for any sparks, flames, or melting.
Observing Results
You must watch the sample closely during and after the test. Look for signs of burning, glowing, or self-extinguishing. Write down what you see. The tester may also record data for you. If the sample catches fire and keeps burning, it does not pass. If the sample stops burning on its own, it passes.
-
Record the time it takes for the flame to go out.
-
Note if the sample drips or melts.
-
Save your results for your report.
Note: Careful observation helps you understand how safe your material is. The glow wire test gives you clear answers about fire risk.
Safety Measures
Safety Protocols
You must follow strict safety protocols when you perform a glow wire test. These rules protect you and your workspace from harm. Always check your equipment before you start. Make sure the Kingpo KP-FT01 Glow Wire Tester sits on a stable surface. Keep the area around the tester clean and free of flammable items.
You should set up good ventilation in your lab. Hot wires and burning samples can release smoke or fumes. Open windows or use an exhaust fan to keep the air fresh. Never leave the tester running without supervision. Stay alert and watch the test from start to finish.
Here is a quick checklist for safety protocols:
-
Inspect the tester and wires for damage.
-
Remove paper, cloth, or plastic from the test area.
-
Turn on ventilation systems.
-
Keep a fire extinguisher nearby.
-
Read the user manual before you begin.
Tip: If you see sparks or flames spreading, stop the test right away and use the fire extinguisher.

Testing Standards and Result Interpretation
International Standards (e.g., IEC 60695)
You need to follow international standards when you perform a glow wire test. These rules help you get results that everyone can trust. The most important standards come from the International Electrotechnical Commission (IEC). Here is a table that shows some key standards and what they cover:
|
Standard |
Description |
|---|---|
|
IEC 60695-2-10 |
General method for the Glow Wire Test |
|
IEC 60695-2-11 |
Glow Wire Ignition Temperature Test |
|
IEC 60695-2-12 |
Glow Wire Flammability Index Test |
You may also see other standards like UL 746A for polymeric materials. These rules make sure your tests match what is needed around the world.
Compliance Steps
You must follow clear steps to meet these standards. First, choose the right test method for your material. Set up your Kingpo KP-FT01 Glow Wire Tester according to the standard you need. Check that your sample size, wire temperature, and test time match the rules. Record all your settings and results. This helps you show that your products are safe.
Tip: The Kingpo KP-FT01 makes it easy to follow these steps. Its touchscreen and automatic data storage help you keep good records for every test.
Interpreting Results
You need to look at your results carefully. The glow wire test checks how your material reacts to heat and if it catches fire. You should pay attention to these main points:
-
Ignition temperature: The lowest temperature where your material starts to burn.
-
Contact time: How long the hot wire touches your sample.
-
Burning duration: How long your sample keeps burning after the wire moves away.
|
Parameter |
Description |
|---|---|
|
Ignition Temperature |
The minimum temperature at which the material ignites when exposed to the heated wire. |
|
Contact Time |
The duration for which the heated wire is in contact with the material during the test. |
|
Burning Duration |
The length of time the material continues to burn after ignition. |
If your sample stops burning quickly or does not catch fire, it passes the test. If it keeps burning, you may need to change your material.
Actions After Testing
After you finish the test, you should review your results and check your records. Clean the tester and get it ready for the next use. You should also calibrate the Kingpo KP-FT01 often. Regular calibration and maintenance keep your results accurate and help you meet safety rules every time.
