UN38.3 testing reviews lithium battery safety performance under transport-related conditions. Common items include altitude simulation, thermal, vibration, shock, external short circuit, impact or crush, overcharge, and forced discharge. Different cells, battery packs, and product combinations require document review according to structure and transport mode.
Information to Confirm Before Testing
| Item | Review Focus |
|---|---|
| Battery information | Confirm cell model, battery pack model, capacity, energy, series/parallel configuration, and protection board information. |
| Product relationship | Separate battery shipped alone, battery packed with equipment, battery contained in equipment, or spare battery. |
| Sample and model | Prepare sample quantity, model differences, battery photos, labels, specifications, and circuit protection information. |
| Transport documents | Prepare UN38.3 report, test summary, MSDS/SDS, transport assessment, and packaging information together. |
| Change control | Evaluate the impact of changes in cell, protection board, capacity, enclosure, supplier, or packaging method. |
Report Boundary
UN38.3 documents should match the specific cell, battery pack model, structure, capacity, and test version. Cell replacement, series/parallel changes, capacity upgrades, protection-circuit changes, or packaging changes may require further review.
Green Ark Recommendation
Green Ark (Shenzhen) Certification Co., Ltd. recommends checking transport documents at the battery selection stage. For cross-border e-commerce, air transport, sea transport, or products shipped with batteries, UN38.3, SDS, transport assessment, and packaging/label documents should be prepared before shipment planning.
