Needle Flame Test Device (IEC 60695).

The Needle Flame Test Device is a test method used to evaluate the fire resistance of electrical equipment and materials. This test is conducted based on the IEC 60695-2-2 standard to simulate the effects of small flames that may arise from fault conditions.

Application Areas:

• Electrical Equipment: Ensures the safety of products such as lighting equipment, low-voltage household appliances, and electronic devices.
• Insulation Materials: Evaluates the combustion properties of insulation materials.

Key Features:

• Flame Height: Adjustable to 12 ± 1 mm.
• Flame Duration: Adjustable between 0 ~ 999.9 seconds, with automatic recording available.
• Angle Adjustment: Adjustable between 0 ~ 45°.
• Gas Source: Operates with butane or propane gas.

The Needle Flame Test Device uses a needle-shaped burner with a specific size (Φ0.9 mm) and operates with a specified gas (butane or propane).

Applicable Standards:

• IEC 60695-2-2: Covers test methods used to evaluate the fire resistance of electrical equipment.
• IEC 60695-11-5: Defines needle flame test methods and requirements.

These standards are critical for ensuring the safety of electrical and electronic devices.

Standard reference

The needle-flame test is specified in IEC 60695-11-5: a small defined flame (representing the effect of a small flame from a fault) is applied to the specimen for a set time to assess whether parts ignite and how flame and burning particles propagate. The device provides the standardised needle-flame burner and timing.
