UN38.3

I. Introduction of International UN38.3 Certification


UN38.3 refers to Section 38.3 of the United Nations Manual on the Testing and Standards of the Transport of Dangerous Goods, specifically for the transport of dangerous goods, referred to as UN38.3. According to the relevant provisions of the IATA "Dangerous Goods Regulations", each airline applies to mobile phone batteries, laptop batteries, walkie-talkie batteries, camera batteries, etc., which are rechargeable lithium batteries, including but not limited to separate or with equipment. Related products such as remote control toy batteries have been tested. The requirements for testing products containing lithium batteries are 38.3 of Part 3 of the UN Manual of Transport and Standards for the Transport of Dangerous Goods, ie UN38.3.

Second, the importance of battery UN38.3 certification

 

As lithium batteries are widely used in mobile communication equipment, electronic digital products, power products, and medical and security fields, the country's transportation monitoring of lithium batteries is becoming more and more strict. Because lithium-ion batteries such as mobile phones and notebook computers are in danger during transportation, in order to ensure the safety of battery air transportation and avoid unsafe incidents, the batteries need to prove that the batteries meet during each type of battery collection and transportation. Section 38.3 (ie UN38.3) of Part 3 of the UN Manual of Transport and Standards for the Transport of Dangerous Goods cannot be accepted for shipment without the UN38.3 Declaration of Conformity.

 

Third, the batteryUN38.3 certificationProduct range


1. Various lead-acid batteries (such as lead-acid batteries for automotive start-up, fixed lead-acid batteries, small valve-regulated sealed lead-acid batteries, etc.);
2. Various types of power secondary batteries (such as batteries for power vehicles, batteries for electric road vehicles, batteries for power tools, batteries for hybrid vehicles, etc.);
3. Various mobile phone batteries (such as lithium ion batteries, lithium polymer batteries, nickel hydrogen batteries, etc.);
4. A variety of small secondary batteries (such as laptop batteries, digital camera batteries, camera batteries, various cylindrical batteries, wireless communication batteries, portable DVD batteries, CD and MP3 player batteries, etc.);
5. Various primary batteries (such as alkaline zinc-manganese batteries, lithium manganese batteries, etc.).

• Logarithmic sweep: keep the maximum acceleration of 1gn from 7 Hz until the frequency is 18 Hz, then keep the amplitude at 0.8 mm (total offset 1.6 mm) and increase the frequency until the maximum acceleration reaches 8 gn (frequency is about 50 Hz) ), keep the maximum acceleration at 8gn until the frequency increases to 200 Hz.

• One of the directions of vibration must be the vertical sample polarity, and each cell is cycled 12 times from three mutually perpendicular directions, 3 hours in each direction for 9 hours.

• The open circuit voltage after the sample test should be no less than 90% of the open circuit voltage before the test. This requirement does not apply to fully discharged batteries and cells.

The sample (battery) should be free of liquid leakage, no venting, no disintegration, no cracking, and no ignition.

T.4 impact test

• Secure the surface of all fittings for each cell and battery sample with a stable bracket.

• For each cell or battery with a half-sinusoidal acceleration of 150gn peak for 6 milliseconds, large batteries and large battery packs must withstand a maximum acceleration of 50gn and a half-sine wave impulse with a pulse duration of 11ms.

• Each battery or battery pack is subjected to three impacts in the positive direction of three mutually perpendicular battery mounting orientations, followed by three impacts in the opposite direction, for a total of 18 impacts.

• The open circuit voltage after the sample test should be no less than 90% of the open circuit voltage before the test. This requirement does not apply to fully discharged batteries and cells.
