Discussion to kick off phase 2 work on defining uniform methods for assessing the risk of thermal propagation across the REESS.

The purpose of this document is to facilitate arrival at a common understanding among EVS informal group contracting parties on thermal runaway propagation risk assessment. Several contracting parties are embarking on a thermal runaway propagation experimental research campaigns for Phase 2 and a common understanding is important to help focus research efforts especially considering the complexity of cost-intensive thermal propagation tests. This approach is expected to further facilitate coordination of contracting parties’ research and to pave a path for effective round-robin testing. For this purpose, this document contains a non-exhaustive list of questions for discussion and agreement among experts.
