IEC 61511 & IEC 61508 Compliance Support

Cradle-to-grave compliance support across the SIS and product safety lifecycle

Technical overview

IEC 61511 & IEC
61508 Compliance Support

Comprehensive IEC 61511 (process sector) and IEC 61508 (electronic systems) compliance — from gap assessment through certification readiness. We support both end-user SIS programmes and equipment manufacturer product certification.

Lifecycle Gap Analysis

Conduct comprehensive gap analysis against IEC 61511 Phases 1–16 lifecycle and IEC 61508-1 to -7; benchmark current practice against each phase requirement; identify gap categories — documentation, technical, competency, organisational.

FSM Programme Design

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.

Procedure & Workflow Authoring

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.

Document Management & Traceability

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.

Competency & Training Programme

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.

Compliance Verification & Certification

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.
