What is a needle flame test?
The full name of IEC 60695-2-2 is Fire hazard testing Part 2: Test methods – Section 2 Needle-flame test. It was prepared by IEC technical committee 89: Fire hazard testing. This section of IEC 60695-2-2 specifies a needle-flame test to simulate the effect of small flames which may result from fault conditions within the equipment, in order to assess by a simulation technique the fire hazard. It applies to electrotechnical equipment, its sub-assemblies, and components and to solid electrical insulating material or other combustible materials.

In the era of electrical generation, the danger of electrical fires already exists, whether it is in the vehicles used, or in all aspects of electrical appliances used in life. How to better prevent these controllable dangers? Whether it is a brand owner, a factory, or a chain store, they must have certain testing requirements for their products. The most common and convincing international standard for electrical combustion is IEC 60695.

Needle Flame Test – IEC 60695-11-5
The needle flame test is used to simulate the effect of small flames that may arise in malfunctioning electrical equipment.A 12 mm high flame held at a 45° angle is applied to the base of a test specimen for a specified period of time. Tissue paper is laid out 200 mm beneath the test specimen (alternatively materials that would normally surround the test material in application may be laid out in place of tissue paper to measure the effect of the test material on surrounding materials).

Needle Flame Tester, to determine the fire hazards of insulation and combustible materials used inside electrical and electronic products, when they are subject to components ignited, the test flame does not cause ignition, or that a combustible part ignited by the test flame has a limited duration of burning or a limited extent of burning, without spreading fire by flames or burning or glowing particles falling from the test specimen.
