IEC 61511 and IEC 61508 Compliance Support
We support compliance from cradle to grave across the safety system and the product safety lifecycle
IEC 61511 and IEC
61508 Compliance Support
IEC 61508 is the foundational standard for the functional safety of electrical, electronic and programmable safety systems, and IEC 61511 is its application in the process sector. Compliance with either is not a certificate obtained once but a lifecycle obligation, a functional safety management regime that holds from conceptual hazard analysis through to decommissioning and is evidenced by a documented trail and demonstrable competence at every stage. We support both sides of that obligation. We help end users build or remediate safety system programmes to IEC 61511 through gap assessment, lifecycle procedures, verification and assessment readiness, and we help equipment manufacturers pursue IEC 61508 product certification through TÜV or exida by developing safety requirements, architectural constraints and the evidence for systematic capability and hardware fault tolerance. The result is a defensible compliance position that withstands assessor, regulator and customer audit.
IEC 61511 and IEC 61508 Compliance Support workflow
Conduct comprehensive gap analysis against IEC 61511 Phases 1, 16 lifecycle and IEC 61508 Parts 1 to 7, benchmark current practice against each phase requirement, identify gap categories, documentation, technical, competency, organisational.
Design Functional Safety Management programme per IEC 61511 Cl.5, roles (FSEng, FSE, FSP), competency framework, training plan, CPD requirement, specify governance structure with FSM steering committee and corporate site interface.
Author lifecycle phase procedures, PHA, SIL allocation, SRS, design, FMEDA, verification, FAT/SAT, installation, commissioning, operations, modification, decommissioning, integrate with site MOC, PHA revalidation, and audit procedures.
Design FSM document management with version control, change history, and chain of traceability from hazard → SIF → SIL → SRS → design → verification → operation, specify electronic system (Aveva PI, SAP, Maximo) integration.
Build competency matrix per role (FSEng, FSP, operator, technician), deliver training to TÜV / exida CFSE / CFSP certification standards, establish CPD programme with annual refresher and triennial recertification.
Engage third party (TÜV, exida, SIRA) for compliance certification per IEC 61511 / 61508 management framework, establish ongoing FSA cycle (Stage 4 every 3, 5 years), maintain compliance register with corporate HSE / corporate engineering.
