Needle Flame Test Device.
Needle Flame Test Device plays a critical role in fire safety assessments of electrical and electronic equipment. This device simulates the impact of small flames on materials, particularly under fault conditions, to minimize fire risk.
What is the Needle Flame Test?
The needle flame test simulates a small flame caused by an electrical fault, such as a short circuit or spark. Engineers expose a test specimen to this flame for a specific duration to determine the material’s ability to resist ignition and self-extinguish. This test is particularly crucial in industries where safety is paramount, such as lighting fixtures, household appliances, and electronic devices.
Purpose of the Test
The needle flame test evaluates whether a flame will ignite a component under specific conditions or cause a combustible reaction. It also measures whether the component’s burning duration or length is limited and assesses flaming or glowing particles or debris that might fall during combustion.
Features of the Needle Flame Test Device
The Needle Flame Controller consists of a needle-shaped burner of 0.9 mm outer diameter, applied at 45° and supplied with butane gas. It assesses fire hazards in equipment caused by ignition under fault conditions by evaluating the flammability, burning duration, and length of the sample. This test device complies with the standard requirements specified in IEC 60695-11-5 and IEC 60598-1, Clause 4.
Application Areas
- Electrical and Electronic Equipment: Used to assess fire risks in cases of short circuits or overheating.
- Lighting Fixtures: Tests the fire resistance of lamps and lighting systems.
- Household Appliances: Ensures compliance with safety standards for white goods and small appliances.
- Insulating Materials: Evaluates the flammability characteristics of electrical insulation materials.
Standards and Compliance
The Needle Flame Test Device is designed to meet international fire safety standards, primarily IEC 60695-11-5. These standards define detailed test procedures and criteria.

Questions fréquentes.
What is the needle flame test and what does it simulate?
The needle flame test simulates a small flame caused by an electrical fault, such as a short circuit or a spark. A test specimen is exposed to the flame for a specific duration to find out whether the material resists ignition and self-extinguishes. The test matters most where safety is paramount, for example in lighting fixtures, household appliances and electronic devices.
Which standards specify the needle flame test?
IEC 60695-11-5 is the main international standard for the needle flame test and defines the test procedures and criteria in detail. The test device itself complies with the requirements specified in both IEC 60695-11-5 and IEC 60598-1, Clause 4.
What burner and gas does a needle flame test device use?
The burner is needle-shaped with an outer diameter not exceeding 0.9 mm; it is supplied with butane gas, and the 12 mm flame is applied to the specimen at a 45° angle. Under fault conditions, the fire hazard from ignition is judged by the specimen's flammability, burning duration and burning length.
What does the needle flame test evaluate on a specimen?
The needle flame test checks whether the flame ignites a component under specific conditions or causes a combustible reaction, and whether the component's burning duration or burning length stays limited. Flaming or glowing particles or debris that fall from the specimen during combustion are also part of the assessment.
Which products and materials are tested with the needle flame test?
The needle flame test is used on electrical and electronic equipment to assess fire risk from short circuits or overheating, and on lighting fixtures to test the fire resistance of lamps and lighting systems. Household appliances, both white goods and small appliances, are tested for compliance with safety standards. Electrical insulating materials are evaluated for their flammability characteristics.
