application of a particular standard may not be mandatory provided that all the safety requirements of the applicable EU
directives are fulfilled.
22.1.2.3
Standards for implementing safety-related controllers
If the functional safety of a machine depends on various control functions, the controller must be implemented in such a way
that the probability of the safety functions failing is sufficiently minimized. EN ISO 13849-1 (formerly EN 954-1) and EN
IEC61508 define principles for implementing safety-related machine controllers which, when properly applied, ensure that all
the safety requirements of the EC Machinery Directive are fulfilled. These standards ensure that the relevant safety
requirements of the Machinery Directive are fulfilled.
Standards for implementing safety-related controllers:
The application areas of EN ISO 13849-1, EN 62061, and EN 61508 are very similar. To help users make an appropriate
decision, the IEC and ISO associations have specified the application areas of both standards in a joint table in the
introduction to the standards. EN ISO 13849-1 or EN 62061 should be applied depending on the technology (mechanics,
hydraulics, pneumatics, electrics, electronics and programmable electronics), risk classification and architecture.
