The UN38.3 certification project is actually drafted and implemented by the United Nations in the United Nations Dangerous Goods Transport Tests and Standards Manual, Part 3, Article 38.3, the specific definition is based on the "Dangerous Goods Transport Rules", this article is only for lithium battery transportation safety carry out testing. Lithium batteries are divided into rechargeable lithium-ion batteries and non-rechargeable lithium metal batteries. Each type of lithium battery must be tested without problems before a UN38.3 safety test report can be issued. At this time, the lithium battery will be considered as capable Safe transportation (more common, such as air transportation and sea transportation), and the packaging method of lithium battery transportation is divided into pure battery individual packaging, packaged with the equipment and transported on the equipment. Any laboratory capable of performing UN38.3 testing can issue this report, but if only the UN38.3 report is available in mainland China, the battery cannot be exported. It is also necessary to provide the identification report of the cargo transportation conditions, referred to as the identification certificate, which is divided into air, sea and land transportation. The identification results of different packages are different, but there is no need to have an identification certificate for shipment at Hong Kong Airport. In order to fully guarantee the safety of the goods during transportation, it is very necessary and meaningful to make a report of the UN38.3 certification project for lithium batteries.

The specific test items of the UN38.3 certification test for lithium batteries are:

1. Altitude simulation test

2. Temperature test

3. Vibration test

4. Impact test

5. External short circuit test

6. Extrusion/impact test

7. Overcharge test

8. Forced discharge test

Because the battery safety test of the above 8 items must be passed to confirm the safety of the battery during transportation, and the same batch of test samples must be tested in order from 1 to 5, so the test cycle takes two weeks.

The materials to be prepared for the UN38.3 certification test of lithium batteries are:

1. Fill in the application form (fill in the battery information)

2. Battery specifications

3. Battery specifications

4. Test samples (the model and watt-hour parameters should be marked on the sample nameplate, and must be consistent with the battery during shipment and transportation)

If you need to issue a report on the identification of the transportation conditions of the goods (air/sea/land), you must also provide the following information

5. Related documents such as power of attorney and transportation declaration

6. Packing pictures (outer packing picture, outer packing open picture, inner packing picture)

(The above information can provide templates)

The certification process of the UN38.3 certification test for lithium batteries is as follows:

1. Sign the quotation

2. Send samples and submit materials

3. Test

4. Application for certification

5. Issue report
