What is IEC 61511 and what does it cover?

IEC 61511 is the sector specific standard for electrical and/or electronic and/or programmable electronic (E/E/PE) systems within the process sector. The series of documents have been developed following the basic safety publication IEC 61508 for application within the process sector.

The standard covers the following aspects of functional safety within the process sector (excluding nuclear):

  • Framework for requirements (hardware, software and integration as a system)

The standard utilises different terminology which is more aligned to the industries which it serves. A safety related system becomes a Safety Instrumented System for instance.
