The group discussed forming subgroups (fluid performance and component performance), scheduling their meetings, and possibly shifting the main reporting call to a monthly cadence. Members shared Summit takeaways including debate over whether fluid flow velocity and erosion should be in scope, test temperature ranges for compatibility, material cleanliness and mold-release contamination, and the need to involve the full value chain and hyperscaler material-qualification experts.
