EN 61511-1:2017+A1:2017

Within the framework of IEC 61508, this standard is tailored to the process industry and its safety systems as a basic safety standard for functional safety. It requires the performance of a hazard and risk analysis in order to be able to derive the specification of safety-related systems. Other safety systems are only considered to the extent that their contribution can be taken into account when considering the performance requirements of the safety systems. The safety-related system includes all components and subsystems from the sensor to the actuator that are required to perform the safety-related function.
