Lithium Battery UN38.3 Certification Test Items and Data Flow

In order to ensure the safety of air transportation and meet the customer's transportation needs for lithium-ion battery-containing goods, according to the relevant regulations of the International Air Transport Association's "Dangerous Goods Regulations", the operation specification for rechargeable lithium batteries, namely UN38.3 test, has been formulated. According to the requirements of civil aviation regulations, airlines and airport cargo collection and transportation departments should review the transportation documents of lithium batteries, and the most important thing is the UN38.3 safety inspection report of each type of lithium battery. The report can be provided by a third-party testing organization designated by civil aviation, or by a battery manufacturer with testing capabilities. If this test report cannot be provided, civil aviation will prohibit lithium batteries from being transported by air.

1. Specific requirements for UN38.3 battery certification

UN38.3 battery refers to Section 38.3 of Part 3 of the "United Nations Manual of Tests and Standards for the Transport of Dangerous Goods" specially formulated by the United Nations for the transportation of dangerous goods. , vibration test, impact test, 55 ℃ external short circuit, impact test, overcharge test, forced discharge test, in order to ensure the safety of lithium battery transportation. If the lithium battery is not installed together with the device, and each package contains more than 24 battery cells or 12 batteries, it must also pass the 1.2-meter free drop test.

2. UN38.3 battery certification test certification process

(1) Sign the quotation.

(2) Send samples and submit materials.

(3) TEST.

(4) Apply for a certificate of appraisal.

(5) Issue a report.

3. UN38.3 battery certification test requires preparation materials

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

(2) Battery specifications.

(3) Cell specifications.

(4) Test the sample (the model and watt-hour parameters must be marked on the sample nameplate, and must be consistent with the battery at the time of shipment). The following information is also required.

(5) Relevant materials such as power of attorney and transportation statement.

(6) Packaging pictures. (Pictures of the outer package, pictures of the outer package opened, pictures of the inner package)

4. UN38.3 battery certification test items

(1) Altitude simulation test; temperature test; vibration test.

(2) Impact test; external short circuit test; extrusion and impact test.

(3) Overcharge test; forced discharge test.

Because the safety guarantee of the UN38.3 battery during transportation must be tested through the above items, and the same batch of test samples must be tested in sequence, so the test cycle takes two weeks.
