UN 38.3 refers to Part 3, Paragraph 3, of the United Nations Handbook on the Testing and Standards of Transport of Dangerous Goods. In order to ensure the safety of lithium battery air transportation and avoid unsafe incidents.
Lithium batteries are classified as dangerous goods and can pose a safety risk if not tested and packaged in accordance with transport regulations.
UN 38.3 Tests series
Li-ion batteries must pass several tests to ensure the relative safety of batteries and cells during transport that vary based on the battery and components.
UN 38.3 test report requires:
- altitude simulation test (Primary and Secondary Cells and Batteries);
- thermal test (Primary and Secondary Cells and Batteries);
- vibration test (Primary and Secondary Cells and Batteries);
- shock test (Primary and Secondary Cells and Batteries);
- 55 °C external short circuit (Primary and Secondary Cells and Batteries);
- impact test (Primary and Secondary Cells and Batteries) including packaging drop test before transportation;
- overcharge (Secondary Batteries);
- forced discharge (Primary and Secondary Cells and Batteries);
Products without the UN38.3 test qualification report can not be accepted.
All electric bike smart lithium-ion batteries made by Tritek are certified with un dot 38.3.
Certification of UN-Products
Is Un 38.3 mandatory?
Nearly all lithium batteries are required to pass section 38.3 of the UN Manual of Tests and Criteria, to ensure the safety of lithium batteries during shipping.
What are UN 3090 and UN 3480?
UN 3090 for lithium batteries and UN 3480 for lithium-ion batteries apply to cells shipped alone, batteries shipped alone, a consignment of cells and batteries, modules or other incomplete battery sub-assemblies, power banks, power packs, and batteries shipped in a separate package from the device they power (even if the device and batteries are on the same consignment or shipment).
UN 38.3 Packaging and Shipping
Recent updates to transportation regulations include new labels to show the risk of fire associated with the battery in the package. Lithium-ion batteries shipped separately should be set to 30% or less of the state of charge (SOC) for air freight transport.
