The Basics of UN 38.3 and its Requirements
Lithium batteries are considered dangerous goods and as such, they must meet certain provisions laid out in the global UN 38.3 standard to be transported. This test standard is part of the dangerous good regulations, and focuses on their transportation, not their electrical safety.
As such, it considers all points where a lithium battery may be transported, from: sub-suppliers to end-product manufacturer; manufacturer to distributor, in or out of the product, in the field, product return or within non-original packaging. It requires several tests:
The most recent update, 6th Edition, Amendment 1, went into effect at the start of the year, and it includes several key changes:
To adhere to the basics of UN 38.3 it is important to get test reports from cell vendors and subcontractors and to complete the test summary for your shipments, maintaining the supporting information. Always consider what level or subassembly of battery will be offered for shipment. The "Battery Assembly" clauses are useful for larger assemblies, as long as cell and "subassembly" level of battery is already tested. Identify the samples tested and the models/versions to be covered by a single test report. Be aware of model number changes, which may call the test summary into question.
