The safety of plants such as chemical plants, refineries or oil and gas production plants in the process industry is becoming increasingly reliant upon complex safety systems. Requirements of these electrical, electronic and programmable electronic safety-related systems (E/E/PES) are described in the internationally acknowledged standard IEC/EN 61508, parts 1-7.

The application standards EN 61511 and VDI/VDE 2180 - derived from the IEC/EN 61508 - define the requirements regarding the application and implementation of these safety-related systems (safety instrumented systems - SIS) in the process industry. They describe requirements of functional safety in process technical plants in detail, starting from the first concept, through design, installation, operation, and maintenance to decommissioning.

If you are a designer, developer or user of safety-related systems, our functional safety experts can support you when required to produce proof or evidence of functional safety within this system.
