Functional Safety Standards

Sira was the first certification body in the world to be accredited for functional safety certification to IEC 61508. Sira assesses a wide range of companies and products involved in many diverse applications supplying for example, the process, machinery, railway and nuclear industries. The relevant standards which are now widely accepted are:

IEC 61508- the generic standard. It provides a firm basis for the specification, design and operation of electrical or electronic (including software controlled) safety systems and allows the potential of this technology to be realised fully and safely. It also forms the basis for related industry-sector standards, such as:

IEC 61511 – Functional Safety of safety instrumented systems for the process industry.

IEC 61513 – Nuclear power plants: Instrumentation and control for systems important to safety.

IEC 62061 – Safety of Machinery: Functional safety of safety-related E/E/PE control systems.

EN 50402 – Detection and measurement of combustible or toxic gases, vapours or oxygen.
