IEC60335-1 clause 30.2.3.2, Annex E Needle Flame Test Apparatus

The Needle Flame Test Apparatus is designed to evaluate the fire hazard of electrical and electronic products, components, insulating materials and solid combustible materials under fault conditions.

The tester applies a controlled needle flame to the test specimen at a specified angle and evaluates whether the material ignites, as well as the flame duration and combustion behavior after exposure.

The equipment is designed in accordance with IEC 60695-11-5 and is applicable to the needle flame testing requirements specified in IEC 60335-1 Clause 30.2.3.2, Annex E, and other relevant standards.

With PLC control and a 7-inch color touchscreen, the SN773 provides automated test operation and convenient parameter monitoring for laboratory and quality-control applications.

The test uses a needle-shaped burner supplied with butane gas. The burner is positioned at 45° to the specimen during the test.

A specified flame is applied to the sample for the required duration. The fire hazard is evaluated based on factors including:

• Whether the specimen ignites
• Whether combustion continues after flame application
• Burning duration
• Flame propagation or combustion behavior

The test helps assess the resistance of materials and components to ignition caused by a small external flame under abnormal or fault conditions.

The PLC control system automates the test sequence and improves testing repeatability.

A user-friendly touchscreen interface allows operators to set and monitor the test parameters conveniently.

The flame height is adjustable to 12 ± 1 mm and can be checked using the supplied flame height gauge.

The integrated timer supports precise measurement of ignition and combustion duration.

The test procedure incorporates an independent air-draft system to help maintain the required testing conditions.
