Flame Testing for Ignition, Burning Behavior, and Fire Hazard Evaluation
Flame testing is used to evaluate how materials, components, and finished products respond when exposed to a defined ignition source. Depending on the governing method, the test may call for a needle flame, a Tirrill or Bunsen-style burner, a wing-tip burner arrangement, or a complete burn-test fixture with specimen support and measurement accessories.
ED&Dās flame test equipment family covers the supporting enclosure, ignition source, and accessory hardware needed for these workflows. That includes ducted flame hoods, needle flame burners, flame height gauges, copper blocks, Tirrill and UL burners, burn test apparatus, and complete test kits.
These products are aligned with testing programs associated with UL 94, IEC 60695-11-5, IEC 60335, ASTM D5025, and ASTM D3713, while final suitability still depends on the exact product standard, burner configuration, flame height, specimen support arrangement, and test sequence.
Important standards note: flame testing is only meaningful when the burner geometry, flame height, gas supply, burner angle, specimen support, hood environment, and timing all match the exact method required by the governing standard.

Frequently Asked Questions
What is the difference between a needle flame burner and a UL burn burner?
A needle flame burner is used for methods that call for a small, defined needle flame ignition source, while UL burn burners such as Tirrill or Bunsen-type systems are used for broader flame and burn test methods that specify different burner geometry and flame conditions.
What does the flame height jig do?
The flame height jig is used to verify the flame height of a needle flame burner so the burner is set to the required flame condition before testing.
Why are copper blocks used with needle flame burners?
Copper blocks with thermocouples are used in calibration and verification work related to the needle flame burner setup, helping the lab confirm the burner condition against the method requirements.
Why would a lab need a flame hood?
A flame hood helps provide a more controlled draft-free environment for flame testing and helps organize burner-based testing on a dedicated bench-top platform.
Can one flame test setup cover every flame standard?
No. Different standards may call for different burner types, flame heights, burner angles, specimen supports, and supporting accessories, so the correct setup depends on the exact method.
What is included in a burn test kit?
That depends on the kit. For example, the ULB-01 includes a burn test apparatus, burner, wing tip, tissue paper, cheesecloth, wire screens, and an angle meter, while the BTK-01 focuses on needle flame testing components.
Send the exact flame or burn test method, and we can help narrow the right burner, hood, accessory, or full kit.
