EN 60695-11-5 Needle flame test

EN 60695-11-5 (or International version IEC 60695-11-5) is a small-scale flammability test intended to evaluate the flammability of electrical and electronic devices. It is designed to replicate the effects of a small flame or an overheating component and assess its impact on the surrounding environment.

What does EN 60695-11-5 involve?

A small flame (~12mm) is lit on a needle-shaped burner and applied at a 45° angle to the test specimen for between 5 seconds and 2 minutes, depending on the classification requirements for the end product. Cotton is placed under the test setup to detect any flaming particles or drops that may spread the burning. The flame is then withdrawn, and the time the specimen burns for and to extinguish itself is measured.

• It does not ignite, or
• The material burned for less than 30 seconds
• The flames or any glowing drops or particles do not spread

Why should I test to EN 60695-11-5?

Fire and flammability tests, such as EN/IEC 60695-11-5 are important for several reasons:

• Selecting the right materials for the product by testing at the design stage can save time and money further down the line.
• Compliance with industry standards and HSE fire safety regulations is vital.
• Improves product safety and liability by reducing the risk of fires, potential product recalls, and legal issues.
