Functional Safety Management

Functional safety standards like IEC 61508, IEC 61511 and associated industry sector standards like the automotive standard ISO 26262 define requirements for functional safety management and functional safety assessments as well as documentation for these procedures. Project managers and engineers have the obligation and responsibility to conform to these requirements throughout all relevant phases of the safety life-cycle. Our audit and certification services are based on these requirements, and we support companies in developing a compliant functional safety management system.

Based on ISO 17021 and ISO 17065, TÜV Rheinland offers its services for auditing and certification of Functional Safety Management Systems (FSMS) and processes according to the requirements of the following international standards:

  • IEC 61508 / IED 61511 – Functional Safety Management (FSM)
  • ISO 26262 – Automotive Functional Safety Management (A-FSM)

Certification Cyles and Maturity Levels


  • Maturity Levels 4 and 5 could be granted also beginning from “Stage 2 – Certification Audit”, if preconditions are fulfilled, proved and accepted, see definitions in table below.









At this level, the Auditee has the capability to manage the MS according to written policies (including objectives).

The Auditee also has evidence to show that personnel who will perform the process have the expertise, are trained and follow written procedures to perform it.

However, at this level, the organization does not have experience to provide services or products to all of the written policies.


Defined -

The performance of a level 3 Auditee can be shown to be repeatable (has practiced for at least one product or service) across the Auditees organization.

The processes have been practiced, and evidence exists to demonstrate that this has occurred.


Improved -Quantitatively Managed

The Auditee is using suitable process metrics, product suppliers control the effectiveness and performance of the product and demonstrate continuous improvement in these areas.


Improved -Optimized
