Standards guide

UN 38.3

Lithium battery transport safety testing

This guide is an engineering orientation, not a substitute for the current official standard text or the requirements of the receiving market. Confirm the applicable edition and scope with the responsible technical or regulatory team.

A defined set of tests for lithium cells and batteries intended to support transport-safety assessment under the applicable UN Manual of Tests and Criteria.

Questions to resolve first

  • What cell or battery is being shipped?
  • Is the sample production or prototype status?
  • What transport mode and packaging apply?
  • Which preliminary design or validation data exist?

How ThermSafe can help

  • Map the requirement to an agreed test scope.
  • Review existing data and identify dependencies.
  • Plan simulation or local physical testing where required.
  • Interpret results for design and validation decisions.
