SIS Failures
Random Hardware Failures:
A failure of a hardware component.
•
Typically caused by component wear, corrosion,
thermal stress, physical manufacturing defects;
•
Most SIS component failures result in a safe failure
causing a spurious activation of the SIS;
•
The failure rates of components can be mathematically
predicted, providing:
•
Average probability of failure data;
•
Typical failure modes for the failure.
