List Version Source flow Name there Why this flow
EF 3.1 db7982d3-297b-453d-a310-99f2f1ee5cf1 nitrogen trifluoride The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu 2026-v1 00f94ae2-e906-5c01-b2f1-c26b83e75b81 Nitrogen trifluoride The CAS numbers are the same (7783-54-2); both name the same compartment.

Characterisation factors

12

Every implementation that says anything about this flow. Published as is what this list did with the row: where more than one implementation states a number and they agree it publishes it as agreed; where only one speaks, as sole; where they disagree it publishes nothing and asks.
