Needle Flame Test Apparatus

Needle Flame Test Apparatus for Manufacturers and Test Labs

This apparatus evaluates how materials and components respond to a small, controlled flame. It supports qualification of plastics, rubber, and electrical parts in labs and production settings. Stable control of the burner and chamber conditions helps deliver repeatable results.

What the Needle Flame Method Evaluates

The method assesses ignition, flame spread, and self-extinguishing behavior when a fine flame is applied to edges, corners, or flat surfaces. It is commonly used for electrical insulation parts, connectors, housings, and other polymer components in electronics, appliances, and vehicle interiors.

Standards and Compliance

Systems conform to IEC 60695-11-5, IEC 60695-2-2, and GB/T 5169.5. Flame height, nozzle dimensions, and timing are set to each method, with clear documentation and preset recipes to simplify compliant testing.

Key Features and Specifications

• Burner and flame control: 0.5 mm nozzle with fine adjustment; 12 mm ±1 mm flame height per method; stable gas regulation and optional pre-heating to keep flame profile steady.


• Timing and positioning: Programmable exposure from seconds to extended durations; automated start/stop and after-flame time capture; adjustable specimen angles (0–45°) and precise burner approach.


• Safety and observation: Safety interlocks, gas cut-off, and over-temperature protection; high-clarity viewing window, internal lighting, and optional camera; efficient ventilation to manage combustion products.


• Construction and quality: Precision-machined hardware, tight-tolerance assembly, and controlled calibration routines. Quality system aligned with ISO 9001; documentation and traceable build records available.


• Data and integration: On-board memory, serial/Ethernet outputs, and exportable logs for traceability. User-level permissions and calibration reminders support consistent operation.


• Typical configurations: Bench-top or floor-standing chamber volumes; optional data logging and automation to suit throughput needs.

Applications

• Electrical and electronics: Terminal blocks, PCB-mounted parts, switch housings, insulation pieces.


• Wire and cable accessories: Cable ties, grommets, plug bodies, strain-relief parts.


• Consumer and appliance housings: Polymer enclosures and trim components.


• Automotive interiors: Trim plastics and other small parts subject to small-flame exposure.


• Plastics and rubber parts: Thermoplastics and elastomers where ignition resistance and self-extinguishing behavior must be verified.

Model Options and Automation

Choose compact bench-top testers for routine checks or larger chambers with automated burner motion for intensive qualification. Optional carousels and programmable sequences support batch testing with consistent timing. Combined suites can pair this method with glow wire or UL 94 to streamline workflows.

Integration, Data, and Traceability

These chambers can connect via serial or Ethernet to export logs and audit trails. Calibration reminders and user permissions help maintain method fidelity across teams and sites.

Test Guidance and Best Practices

Follow specimen conditioning and positioning per the applicable standard. Use templates and adjustable fixtures to mark edge, corner, or surface exposure points. Check flame height before each run and verify timing devices at defined intervals.

Related Equipment

• Glow wire tester for hot-wire ignition assessment.


• UL 94 horizontal/vertical burning chambers for material classification.


• Precision burner nozzles and adjustable specimen clamps to improve repeatability.

Services and Support

Installation, on-site training, and technical support help teams start quickly and maintain reliable operation. Preventive maintenance and routine calibration with certified tools sustain performance over time.

FAQ

Q: Which standard should I use for my component?

A: Select the method referenced by your product standard or customer requirement. If unsure, compare IEC 60695-11-5, IEC 60695-2-2, and GB/T 5169.5 against your product category and safety objectives.

Q: How is the flame height verified?

A: Set the burner to the specified height using a gauge or reference mark, then confirm visually and record the setting before testing, as required by the method.

Q: How do I choose between bench-top and larger chambers?

A: Consider specimen size, required automation, and throughput. Bench-top units suit routine checks; larger enclosures with motion control support frequent qualifications and varied sample geometries.

Q: How does this differ from glow wire or UL 94?

A: Needle flame applies a small flame to features and edges. Glow wire uses a heated element for ignition risk, while UL 94 classifies vertical/horizontal burning behavior.
