Component data
Draft: typed from the cited tables and tested against known values, not yet checked by an engineer. Typed from the cited tables and checked by tests against known values (Antoine at the normal boiling point, Cp at 298 K). Not yet checked against the book by an engineer (lib/process/data.js, D-CH4, O7).

Failure data
No failure rates. CadCraft does not supply any: a rate is only as good as the plant and the period it was counted on, so you bring your own, with its source.
To add your own rates, make a file from a CSV of mode, rate, unit, basis and source with tools/library/components/failure-import.mjs and upload it here as a new version of this item (Upload). The rates stay marked as yours or the community's, and the record's review state does not change.
