In recent years, with the steady increase in the demand for batteries for portable products, the market demand for batteries is also increasing year by year. Compared with other types of batteries, lithium batteries have advantages such as higher energy density, longer cycle life and more green environmental protection, which are favored by the market and have become mainstream batteries in the consumer market.
But at the same time, due to the high energy density, lithium batteries are weak in their own energy control, and are prone to fire and explosion under extreme conditions. In view of the potential safety hazards of lithium batteries, the United Nations has classified them as Class 9 dangerous goods. , so it cannot be transported as general cargo. It is necessary to hold a cargo transportation safety appraisal report issued by a third-party inspection and testing agency with relevant qualifications, and the UN38.3 test is an extremely important battery safety test.
What is UN38.3 testing?
UN38.3 refers to Section 38.3 of the United Nations Manual of Tests and Criteria for the Transport of Dangerous Goods specially formulated by the United Nations for the transport of dangerous goods, referred to as UN38.3. That is to say, before the lithium battery is required to be transported, it must pass the high simulation, high and low temperature cycle, vibration test, impact test, 55 ℃ external short circuit, impact test, overcharge test, and 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 testing is a prerequisite for the transportation of lithium batteries. It selects various types of lithium batteries safely at the front end, thereby ensuring the safety of the transportation of lithium batteries at the back end.
