Differences between the 8th ed. and the 7th ed. of UN 38.3
Dear Valued Client,
Greetings.
We would like to inform you that the United Nations Expert Committee on the Transport of Dangerous Goods and on the Globally Harmonized System of Classification and Labelling of Chemicals officially released the 8th revised edition of the "Manual of Tests and Criteria" on November 27, 2023.
I. In the UN 38.3 section, the main differences in the new version are as follows:
1. Addition of Sodium-Ion Battery Testing Terms:
The 23rd revised edition of the United Nations TDG regulations officially introduced dedicated entries for sodium-ion batteries and related equipment: UN 3551 and UN 3552. Testing requirements for UN 38.3 for sodium-ion batteries have been added, bringing comprehensive control. Like lithium-ion batteries, Sodium-ion batteries now require UN38.3 testing before transportation. Therefore, Chapter 38.3 has also been revised in the 8th revised edition of the United Nations Manual of Tests and Criteria, has been amended to include section 38.3.3.2, "Testing of sodium ion cells and batteries," specifying detailed testing requirements for sodium-ion batteries.
2. The testing requirements for battery assemblies have been modified in 38.3.3.1 Testing of lithium cells and batteries, with the addition of sodium-ion batteries also have the same requirements:
For battery assemblies without overcharge protection, if it is designed solely for use as components providing overcharge protection for other batteries, devices, or vehicles, then:
- Verification of overcharge protection is required in other batteries, devices, or vehicles.
- Charging systems without overcharge protection requires a physical system or programmatic control to prevent from being used for differential comparison.
II. Comparison of test differences between sodium-ion batteries and lithium-ion batteries
1. Sodium-ion batteries do not require T.8 forced discharge test.
2. For sodium-ion cells or single-cell sodium-ion batteries, during T.6 crush/impact testing, the cells are in a fully charged state.
III. Sampling Requirements for UN38.3 testing of sodium ion batteries
- Single cells: 20 pcs
- Single cell batteries: 18 pcs of battery, 10 pcs of cell
- Small battery packs (≤12Kg): 16 pcs of battery, 10 pcs of cell
