Standards For Implementing Safety-Related Controllers - Siemens Sinamics S120 Function Manual

defined for a particular machine, type B standards can be applied when the machine is
constructed.
A complete list of the standards specified and the mandated draft standards are available on
the Internet at the following address:
http://www.newapproach.org/
Recommendation: Due to the rapid pace of technical development and the associated
changes in machine concepts, the standards (and C standards in particular) should be
checked to ensure that they are up to date. Please note that the application of a particular
standard may not be mandatory provided that all the safety requirements of the applicable
EU directives are fulfilled.

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 safety functions failing in a dangerous
fashion is sufficiently minimized. EN ISO 13849-1 (formerly EN 954-1) and 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.

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,
