IEC 61508
Functional Safety of E/E/PE Safety-Related Systems
IEC 61508 is the umbrella functional safety standard for E/E/PE safety-related systems. It defines the lifecycle, targets, systematic capability, hardware integrity, and assessment expectations that sector standards build on.
It applies across machinery, mining, energy, robotics, and other industrial products when a safety function depends on control logic, sensors, actuators, diagnostics, or software. The practical unit of compliance is a safety function, not a whole product.
CSA supports lifecycle planning, allocation, and fault analysis review, certification evidence, independent assessment readiness, team training, and staffing for functional safety managers and engineers.
