I. What is the test report of UN38.3
UN38.3 Test report is Part 3, paragraph 38.3, of the United Nations Manual of Tests and Standards for the Transport of Dangerous Goods, which is specially formulated by the United Nations for the transport of dangerous Goods.
Before lithium battery transportation, need to pass the high simulation, high and low temperature cycle, vibration test, impact test, 55℃ external short circuit, impact test, overcharge test, forced discharge test, to ensure the safety of lithium battery transportation. If the lithium battery is not installed with the device, it must also pass the 1.2m free drop test.
UN38.3 is mainly used to ensure the safety of air transportation and meet customers' transportation demand for cargo containing lithium batteries. According to the relevant provisions of the Dangerous Goods Regulations of the International Air Transport Association, the operation specification of rechargeable lithium batteries has been formulated, namely the test of UN38.3 (UNDOT).
According to the requirements of the civil aviation regulations, the airlines and the cargo receiving and handling department of the airport should conduct the examination of the transportation documents of lithium batteries. The important thing is the UN38.3 safety test report of each type of lithium batteries. The report can be provided by a third-party testing institution designated by civil aviation or by battery manufacturers with testing capabilities. If the test report is not provided, the civil aviation will ban the lithium battery for air transport.
