Standards For Implementing Safety-Related Controllers - Siemens SINAMICS V90 Operating Instructions Manual

8.1 Standards and regulations
Type C standards/product standards
C standards are product-specific standards (e.g. for machine tools, woodworking machines,
elevators, packaging machines, printing machines etc.). Product standards cover machine-
specific requirements. The requirements can, under certain circumstances, deviate from the
basic and group standards. Type C/product standards have the highest priority for machine
manufacturers who can assume that it fulfills the basic requirements of Annex I of the
Machinery Directive (automatic presumption of compliance). If no product standard has been
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:

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.
8.1.2.3

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.
