UN38.3 Certification Test Report for Lithium Batteries

To market lithium batteries, especially for export, UN38.3 certification is required. So, what is un38.3 certification, what is its scope, and what does the testing involve? China JJR Laboratory provides the answers.

What is un38.3 Certification?

UN38.3 refers to Section 38.3 of Part 3 of the "United Nations Manual of Tests and Criteria" for the transportation of dangerous goods. UN38.3 is a safety performance testing report for batteries, conducting a comprehensive set of safety performance tests on various types of batteries according to both domestic and international standards. This ensures product quality and safety, helping battery manufacturers meet standards and enhance export capabilities.

In simple terms, it is safety testing for the transportation of lithium batteries.

What is the Scope of UN38.3 Certification?

1. Various types of lithium-ion secondary batteries (e.g., power vehicle batteries, electric road vehicle batteries, electric tool batteries, hybrid vehicle batteries, etc.)

2. Various mobile phone batteries (e.g., lithium-ion batteries, lithium polymer batteries, etc.)

3. Various small secondary batteries (e.g., laptop batteries, digital camera batteries, camcorder batteries, various cylindrical batteries, wireless communication batteries, portable DVD batteries, CD and MP3 player batteries, etc.)

4. Various primary batteries (e.g., lithium-manganese batteries, etc.)
