All Li-ion cells and packs shipped must be tested to meet the Recommendations on the Transport of Dangerous Goods on lithium-ion batteries for air shipment, rules set by the United Nations (UN).
The electrical test stresses the battery by applying high heat, followed by a forced charge, abnormal discharge and an electrical short.
During the mechanical test the battery is crush-tested and exposed to high impact, shock and vibration.
The UN Transport test also requires altitude, thermal stability, vibration, shock, short circuit and overcharge checks.
The section 38.3 of the UN Manual of Tests and Criteria (UN Transportation Testing) specify the following tests:
T1 – Altitude Simulation
T2 – Thermal Test
T3 – Vibration
T4 – Shock
T5 – External Short Circuit
T6 – Impact
T7 – Overcharge
T8 – Forced Discharge
Genport tests all the designed battery packs according to UN 38.3.
