Failure data sources

The failure rates and modes used in safety analysis are taken from industrial and military sources. Paitron integrates multiple well-established reliability databases to provide comprehensive failure data for components.

Built-in data sources

note

Some data sources support calculation of failure rates adjusted for operating conditions (column Operating conditions). This allows for more accurate reliability predictions based on the actual operating environment of the system.
