IEC 61511
Process Industry Safety Instrumented Systems
IEC 61511 applies principles to safety instrumented systems in process industries. It covers the SIS lifecycle from hazard analysis and allocation through operation, proof testing, and modification.
Use it for process plants, energy systems, chemical facilities, and other installations where instrumented protections reduce process risk. The standard expects lifecycle management as much as design evidence.
CSA helps with verification, lifecycle audits, proof-test strategy, assessment readiness, training, and staffing for process functional safety roles.
