The best glow wire test apparatus for IEC standards should match the IEC 60695 test method, provide stable temperature control, accurate contact force, repeatable specimen movement, safe operation, and reliable documentation for laboratory audits.
For laboratories testing electrical and electronic products, household appliances, lighting components, connectors, switches, insulating materials, plastic enclosures, or cable-related components, glow wire testing is an important fire hazard assessment method. It helps simulate abnormal heat caused by overheated parts, loose electrical connections, overloaded resistors, or internal fault conditions.
KINGPO provides a complete Flame Test Equipment range for laboratories that need standard-oriented fire hazard testing solutions, including glow wire testing, needle flame testing, horizontal and vertical flame testing, cable flame propagation testing, hot wire ignition testing, and burner calibration accessories.
Quick Answer: What Should a Good IEC Glow Wire Tester Include?
A reliable IEC glow wire test apparatus should include:
- Stable glow wire temperature control for common IEC test temperatures
- Standardized glow wire structure and thermocouple arrangement
- Controlled contact force between the glow wire and specimen
- Controlled specimen movement and penetration depth
- Accurate timing for application time, ignition time, and flame extinction time
- Clear observation of ignition, afterglow, molten drops, and wrapping tissue ignition
- Enclosed test chamber with exhaust and operator protection
- Calibration support for temperature, force, timing, and movement
- Test data recording and documentation support
- Fixture flexibility for materials, components, and end products
For most manufacturer QC labs, R&D labs, and third-party testing laboratories, a semi-automatic or automatic Glow Wire Tester is usually more suitable than a fully manual device because it reduces operator influence and improves repeatability.
Why Glow Wire Testing Matters for IEC Compliance
Electrical products can fail because of abnormal heat inside the product, not only because of external flame exposure. A connector, terminal block, insulation part, plastic housing, switch, relay, PCB support, or appliance component may be exposed to local overheating during fault conditions.
Glow wire testing helps laboratories evaluate:
- Whether the material ignites under defined thermal stress
- Whether flame self-extinguishes within the required time
- Whether molten or burning particles ignite the wrapping tissue
- Whether the end product has limited ability to propagate flame
- Whether the selected plastic or insulation material is suitable for the application
- Whether production batches remain consistent before certification or market release
For laboratories that also need to evaluate small flame fault conditions, KINGPO’s Needle Flame Test Apparatus can be used as a complementary fire hazard test method. Glow wire testing simulates heat from a glowing element, while needle flame testing evaluates the effect of a small internal flame on products and materials.
Which IEC Standards Are Related to Glow Wire Testing?
IEC 60695-2-10: Apparatus and Common Test Procedure
IEC 60695-2-10 is the foundation for selecting a glow wire test apparatus. It defines the glow-wire apparatus and common test procedure used to simulate thermal stress from glowing elements or overloaded resistors.
For equipment selection, this part is especially important because it relates to:
- Glow wire construction
- Temperature measurement
- Contact force
- Specimen movement
- Timing
- Test chamber conditions
- Repeatability of the test setup
For this application, the recommended product anchor is IEC 60695-2-10 Glow Wire Test Apparatus.
IEC 60695-2-11: Glow-Wire Test for End Products
IEC 60695-2-11 is used for end-product evaluation. It is relevant when the laboratory needs to test a finished product, component assembly, or accessible test point rather than only a standard material specimen.
This test is important for manufacturers of:
- Household appliances
- Lighting products
- Electrical accessories
- Switches and sockets
- Connectors and terminal blocks
- Plastic housings and assemblies
When end-product testing is combined with other flame risk evaluations, laboratories may also consider the Horizontal Vertical Flame Test Chamber for UL 94 and IEC 60695-11-3 / IEC 60695-11-4 related flammability comparison.
IEC 60695-2-12: GWFI for Materials
IEC 60695-2-12 is used for Glow Wire Flammability Index, or GWFI. It is mainly used for material evaluation and comparison.
GWFI is useful when engineers need to compare plastics, insulating sheets, or flame-retardant material formulations before choosing a material for final product design.
IEC 60695-2-13: GWIT for Materials
IEC 60695-2-13 is used for Glow Wire Ignition Temperature, or GWIT. It helps evaluate the ignition tendency of materials under glow wire exposure.
GWIT is often used during R&D, supplier qualification, and material selection.
For laboratories evaluating ignition risk by heating wire methods, the IEC 60695-2-20 Hot Wire Ignition Tester can also be considered as part of a wider material ignition testing program.
KINGPO Recommendation: Match the Tester to the Laboratory Workflow
There is no single “best” glow wire tester for every laboratory. The right configuration depends on the test object, applicable standard, testing frequency, automation requirement, fixture design, and documentation level.
For Manufacturer Quality Control Labs
A manufacturer QC lab usually needs stable and easy-to-operate equipment for repeated inspection of materials or components.
Recommended configuration:
- Stable temperature control
- Repeatable contact force
- Standard specimen holder
- Clear observation window
- Safe enclosed chamber
- Simple operation interface
- Basic test record support
Best suited for:
- Plastic housings
- Insulating materials
- Switch components
- Connector parts
- Appliance components
- Lighting product components
For this type of lab, KINGPO’s Glow Wire Tester is suitable as the core instrument for glow-wire-based material and product evaluation.
For R&D Laboratories
R&D labs often test different materials, shapes, and structures before final product design. Fixture flexibility and repeatable setup are more important than basic manual operation.
Recommended configuration:
- Adjustable specimen fixture
- Flexible sample positioning
- Stable heating and contact system
- Repeatable movement control
- Data recording for comparison
- Support for material and end-product evaluation
For R&D teams comparing plastic materials, flame-retardant formulations, and insulation structures, the IEC 60695-2-20 Hot Wire Ignition Tester and Horizontal Vertical Flame Test Chamber can be used together with glow wire testing to build a broader flammability evaluation workflow.
For Third-Party Testing Laboratories
Third-party laboratories need repeatability, traceability, and documentation. Manual variation should be minimized as much as possible.
Recommended configuration:
- Semi-automatic or automatic operation
- Accurate timing and movement control
- Calibration documentation
- Clear test records
- Safety enclosure and exhaust support
- Repeatable fixture setup
- Audit-ready reporting workflow
For third-party labs that cover multiple fire safety methods, KINGPO’s Flame Test Equipment category allows the lab to build a complete equipment set, including glow wire, needle flame, horizontal vertical flame, hot wire ignition, cable flame propagation, and flame calibration accessories.
For Cable and Wire Testing Laboratories
If the lab mainly tests cable insulation, sheath materials, or single insulated wires, glow wire testing alone may not be enough. Cable flame propagation behavior should be evaluated with a dedicated vertical cable flame test system.
For this application, KINGPO provides Flammability Test for Cables IEC 60332 Vertical Flame Tester, which is suitable for single cable vertical flame propagation assessment.
For Refrigerant and Combustible Gas Safety Testing
Some laboratories also need to evaluate combustion characteristics of refrigerants or flammable gas mixtures, especially for HVAC, heat pump, and low-GWP refrigerant applications.
For these applications, the ISO 817 & IEC 60335-2-40 Burning Velocity Test Apparatus is more suitable than a glow wire tester, because it focuses on laminar burning velocity rather than solid material ignition.

KINGPO vs Basic Glow Wire Testers: What Should Labs Compare?
When comparing KINGPO KP-FT01 with other glow wire test apparatus options, laboratories should not compare only the product name, display type, or price. The real comparison should focus on test reliability.
1. Standard Coverage
Check whether the apparatus is suitable for IEC 60695-2-10 apparatus requirements and whether it can support the intended applications under IEC 60695-2-11, IEC 60695-2-12, or IEC 60695-2-13.
A tester may look similar, but fixture design, movement control, temperature measurement, and documentation support can affect whether it is suitable for the lab workflow.
2. Temperature Stability
Glow wire testing depends heavily on stable temperature before contact with the specimen. Temperature drift may affect ignition behavior, flame duration, and result repeatability.
A good apparatus should provide controlled heating, reliable temperature measurement, and calibration support.
3. Contact Force and Penetration Depth
Contact force affects heat transfer between the glow wire and the specimen. If the force is not controlled correctly, the test may become operator-dependent.
For repeatable testing, laboratories should check:
- Contact force control
- Penetration depth control
- Specimen movement control
- Sample holder stability
- Adjustment method before testing
4. Timing and Observation
Glow wire testing requires accurate timing for glow application, ignition observation, and flame extinction. Operators must also observe afterglow, molten drops, burning particles, and wrapping tissue ignition.
A practical tester should make timing and observation easy, especially for frequent testing.
5. Safety and Exhaust
Glow wire tests may produce flame, smoke, fumes, and hot residues. A suitable laboratory apparatus should include a safe chamber, observation window, exhaust connection, and operator protection features.
This is especially important for labs performing repeated testing on plastics and insulation materials.
6. Burner Calibration and Flame Verification
For laboratories using flame-based methods such as needle flame or 50W flame testing, calibration accessories are also important. KINGPO provides the IEC 60695-11-4 50W Test Flame Burner and IEC 60695-11-4 Figure 1 Copper Block for flame verification and burner-related calibration work.
These products are not replacements for a glow wire tester, but they are useful when a lab needs to maintain traceable flame test conditions across multiple IEC 60695 test methods.
How to Choose the Best Glow Wire Tester for Your Lab
Before selecting a glow wire test apparatus, laboratories should answer these questions:
- Which IEC 60695 part applies to your test?
- Are you testing a material specimen, component, or end product?
- Do you need GWFI, GWIT, end-product testing, or a combination?
- What test temperature points are required?
- What is the sample size, shape, and thickness?
- Do you need a standard fixture or customized fixture?
- How often will the lab perform the test?
- Is manual operation acceptable, or is semi-automatic operation preferred?
- Do you need test data recording and report support?
- What calibration documents are required by your quality system?
- Does your lab have proper ventilation and exhaust conditions?
- What power supply and installation space are available?
- Do you also need needle flame, UL 94, cable flame, or hot wire ignition testing?
If the lab cannot answer these questions clearly, the supplier should help clarify the test scope before quoting.
Recommended KINGPO Configuration Approach
KINGPO recommends choosing a glow wire tester according to the actual laboratory scenario.
For routine QC testing, choose a stable and easy-to-operate IEC 60695-2-10 Glow Wire Test Apparatus.
For R&D testing, choose a configuration with fixture flexibility and adjustable test setup.
For third-party testing, choose a configuration with stronger repeatability, calibration support, and documentation workflow.
For laboratories covering several fire hazard methods, combine glow wire testing with Needle Flame Test Apparatus, Horizontal Vertical Flame Test Chamber, Flammability Test for Cables IEC 60332 Vertical Flame Tester, and IEC 60695-2-20 Hot Wire Ignition Tester.
This approach helps avoid two common purchasing problems:
- Buying a low-cost tester that cannot support future standard-based testing needs
- Buying an over-complex system that does not match the actual laboratory workflow
Common Mistakes When Buying a Glow Wire Test Apparatus
Mistake 1: Choosing Only by Price
A low-cost tester may be acceptable for basic internal screening, but it may not provide the repeatability, documentation, or fixture flexibility required for IEC-related laboratory work.
Mistake 2: Ignoring the Applicable IEC Part
IEC 60695-2-10, IEC 60695-2-11, IEC 60695-2-12, and IEC 60695-2-13 are related but not identical. The laboratory should confirm whether the test is for apparatus setup, end products, GWFI, or GWIT.
Mistake 3: Overlooking Sample Fixtures
Many testing errors come from poor specimen positioning. A stable and suitable fixture is essential for repeatable heat transfer and observation.
Mistake 4: Not Planning Calibration
Temperature, force, timing, and movement-related parameters should be checked regularly. Without calibration planning, test results may be difficult to defend during audits or customer review.
Mistake 5: Treating Glow Wire Testing as the Same as Needle Flame or UL 94
Glow wire testing, needle flame testing, and UL 94 testing evaluate different fire hazard scenarios. They are not interchangeable. The correct test method should be selected according to the product standard and risk scenario.
For small flame fault simulation, use a Needle Flame Test Apparatus. For horizontal and vertical burning behavior of plastic materials, use a Horizontal Vertical Flame Test Chamber. For single cable flame propagation, use Flammability Test for Cables IEC 60332 Vertical Flame Tester.
Mistake 6: Using the Wrong Tester for Oil or Enclosure Fire Risk
Some applications involve special fire scenarios, such as hot flaming oil exposure in equipment enclosure evaluation. In this case, a glow wire tester is not the correct method. KINGPO provides the IEC 60950-1 Annex A.3 Hot Flaming Oil Tester for this specific test scenario.
