UN EN 3481 Standard Test Method for Lithium-Ion Batteries

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of UN EN 3481 testing. UN EN 3481 batteries are rechargeable lithium-ion batteries contained in or packaged with equipment.

UN EN 3481 lithium-ion batteries are classified as:

• Class 9 – UN EN 3481 – Lithium-ion batteries packed in or with the equipment but not connected to the source;
• Class 9 – UN EN 3481 – Source-installed/integrated lithium-ion batteries packed in or with the equipment.

There are different requirements that need to be verified for each battery model:

• Battery type;
• Weight of the battery;
• Dimensions of the battery;
• Battery capacity;
• Mode of transport.

Lithium batteries are designed to provide high levels of power and can generate significant amounts of electrical energy. So in case of a short circuit, such batteries can sometimes generate a large amount of heat. In addition, the chemical content of these batteries that are damaged or incorrectly designed or installed can cause a fire. For these reasons, the shipment of such batteries is controlled by safety regulations.

While all lithium batteries are classified as dangerous goods (also referred to as dangerous goods), there are exceptions that facilitate air shipment rules for commonly used small-size batteries. Such common lithium batteries are only accepted in these terms when the batteries are packaged with or contained within the equipment.
