This equipment simulates a glowing element inside electrical products to assess ignition resistance, after-flame, and after-glow. It determines GWIT and GWFI with repeatable accuracy. Typical parts include appliance components, terminal blocks, connectors, switchgear, lighting fixtures, and wire and cable accessories. As an ISO 9001–certified manufacturer in Dongguan, we supply turnkey systems for QC/QA and R&D with precise control, automation, and safe operation.
The system is built around IEC 60695-2-10. It supports GWFI per IEC 60695-2-11 and GWIT per IEC 60695-2-12/-13. Methods aligned with UL 746A and relevant EN/ISO equivalents are available. The tester maintains specified temperatures and forces with traceable measurement and automatic timing to generate consistent, compliant results.
A high-stability heating loop and contact thermocouple with closed-loop PID enable fast heat-up, minimal overshoot, and tight stability. Digital setpoints, ramps, and live display improve repeatability.
Automatic approach/retreat, interlocked doors, spark-resistant enclosures, and fume extraction interfaces protect operators. Programmable dwell and force, plus auto-stop on flame-out or time-out, help reduce human error and raise throughput.
Software captures temperature, after-flame/after-glow times, and GWIT/GWFI outcomes. Export reports via USB/Ethernet, maintain audit trails, and add an optional camera for ignition documentation and training.
CNC-machined fixtures, heat-resistant materials, and robust sensors ensure alignment, measurement stability, and long service life.
Single-station models minimize footprint and cost. Dual-station systems double capacity and allow parallel conditioning, each with independent controls.
Support for standard glow-wire temperature points with fine resolution and stability. Choose thermocouple types and traceable calibration packages to match internal quality protocols.
Add high-speed imaging, event-based timers, and method-ready report templates to capture ignition onset and after-flame durations with auto-filled compliance summaries.
Tailor specimen holders, enclosures, language packs, and interfaces to fit unique parts and lab workflows. Options include private labeling and LIMS/MES connectivity.
Standard power input with benchtop or cart-mounted formats. Provides ventilation interfaces for smoke removal and optimized clearances for safe placement and maintenance.
Condition specimens per method, verify dimensions and surface state, and mount consistently to achieve repeatable contact and force.
Preheat to target temperature. Apply the glowing element at the specified force and time, then record after-flame/after-glow. Determine GWFI/GWIT and store time‑stamped records with operator IDs.
Inspect heating loops, verify thermocouples, calibrate force, and clean the chamber on a set schedule. Use traceable calibration to sustain accuracy.
Our team contributes to national standards and holds utility model patents that enhance temperature stability and force consistency.
ISO 9001–certified production, in-house CNC, and dedicated calibration/reliability labs validate performance before shipment.
We provide installation, training, spare parts, remote diagnostics, and long-term technical support through a global partner network.
Related solutions include UL 94 chambers, needle-flame testers, CTI testers, and environmental chambers for temperature/humidity and thermal shock.
Unlike UL 94 or needle-flame tests that use an external flame, this method simulates resistive heating faults from glowing elements inside devices. It is ideal for parts not exposed to open flame and complements other flammability tests.
Assess housings, coil formers, terminal blocks, and insulating parts for appliance and ICT safety.
Qualify connector shells, lamp holders, sockets, and cable management components for ignition resistance.
Validate switches, control panels, and interior components to help reduce fire risk and support market access.
For assessing ignition from small flames; complements glow-wire evaluations.
For material classification under standardized flame exposure.
For comparative tracking index under electrical stress and contamination.
For temperature/humidity conditioning and thermal shock cycles.
Q: How do I choose the target temperature?
A: Select temperatures specified by the product standard and material class. Common setpoints include 550–960°C for appliance and component parts.
Q: What is the difference between GWIT and GWFI?
A: GWIT relates to the temperature at which ignition occurs under specified conditions. GWFI indicates whether a material self-extinguishes and limits spread after contact.
Q: Do I need fume extraction?
A: Yes. Provide ventilation or connect to a fume extraction system to remove smoke and combustion products per lab safety policies.
Q: How often should I calibrate?
A: Verify temperature and force regularly and schedule traceable calibration at intervals set by your quality system and usage intensity.
