ISA worked with industry experts who are active on the ISA/IEC 61511 standard committee to develop three certificate exams that are designed to increase knowledge and awareness of the ISA/IEC 61511 standards. Compliance with the standard requires a focused and continuous approach to functional safety. The standard is a performance-based standard, so there is a need for competent and qualified people to develop and monitor the application of the standard to a facility or process.
Analyze safety system configurations and technologies to verify SIL compliance using hardware fault tolerance, diagnostic coverage, and safe failure fraction criteriaEvaluate existing and proposed systems against SIL performance requirements to determine upgrade needsOptimize manual test intervals using system modeling to balance testing frequency against risk and operational costModel system reliability accounting for common cause factors, diagnostic levels, imperfect manual testing, and confidence limitsApply detailed design requirements including non fail-safe design, interface requirements, and dual-use control and safety device considerations
