According to the United Nations "on the transport of dangerous goods recommendations model regulations" requirements, lithium batteries in the application for air maritime identification, in addition to the UN38.3 report to provide, depending on the situation also need to provide 1.2 meters drop report.
Why a 1.2 meter drop test?
the 1.2-meter drop test can simulate the actual situation when the package falls freely on the ground. Through this test, the damage of the product can be understood and the accidental drop of the product packaging components during transportation, loading and unloading, handling and other processes can be evaluated, so as to improve and perfect the packaging design and other measures according to the actual situation of the product and within the standard range, so as to ensure the safety of freight transportation and reduce potential safety hazards in transportation.
During the transportation of battery goods, combustion and explosion accidents occur from time to time due to falling and collision. Therefore, the battery package must be able to withstand falling on a hard, inelastic horizontal surface from the location of the most damage caused by the height of 1.2 meters. After the test, such as the top, bottom, long and short sides and edges are not broken, the battery is not damaged, no lead to battery direct contact with the movement, no content leakage, that is qualified.
what is the 1.2 meter drop test applicable to?
it is suitable for small energy lithium batteries to be transported separately or packaged with equipment for transportation.
Note: Small energy lithium battery refers to lithium metal battery with lithium content not exceeding 1g or lithium metal battery pack with lithium content not exceeding 2g; or lithium ion battery with rated watt-hour value not exceeding 20Wh or battery pack not exceeding 100Wh.
Not applicable to lithium batteries installed in equipment
Not applicable to high-energy lithium batteries
note: Large energy lithium batteries refer to lithium batteries that exceed the limit of small energy lithium batteries.
how is the 1.2 meter drop test performed?
under the condition of 20±5 ℃, the packing box containing lithium battery is free to fall from the top, bottom, long side, short side and edge angle respectively from the height of 1.2m according to the predetermined state and collide with the impact table.
1.2 m drop test sample delivery requirements
the package must be a complete package and must be completely consistent with the complete product of the packaging operation during actual transportation, and the packaging of the sample for inspection must be completely consistent with the packaging during export customs clearance.
