Series of standards EN 61508 (VDE 0803)

The series of standards describe state--of--the--art technology.
EN 61508 is not harmonized in line with any EU directives, which means that an
automatic presumption of conformity for fulfilling the protective requirements of a
directive is not implied. However, the manufacturer of a safety--related product can
use EN 61508 to fulfill basic requirements from the European directives according
to the new concept. For instance in the following cases:
S If no harmonized standard exists for the application in question. In this case, the
manufacturer can use EN 61508, although no presumption of conformity ap-
plies here.
S A harmonized European standard (e.g. EN 62061, EN ISO 13849,
EN 60204--1) makes reference to EN 61508. This ensures that the appropriate
requirements of the directives are complied with ("standard that is also applica-
ble"). If the manufacturer correctly applies EN 61508 in the sense of this refe-
rence and acts responsibly, then he uses the presumption of conformity of the
referencing standard.
EN 61508 covers all the aspects that must be taken into account when E/E/PES
systems (electrical, electronic, and programmable electronic systems) are used in
order to execute safety functions and/or to ensure the appropriate level of functio-
nal safety. Other hazards, e.g. hazards as a result of electric shock are not inclu-
ded in the standard.
A new aspect of EN 61508 is its positioning as "International Basic Safety Publi-
cation", which makes it a framework for other sector--specific standards (e.g.
EN 62061). As a result, this standard is now accepted worldwide, particularly in
North America and in the automotive industry. Today, many regulatory bodies
already specify it, e.g. as basis for NRTL listing.
A new aspect of EN 61508 is also its system approach. This extends the technical
requirements to the complete safety installation -- from the sensor to the actuator --
the quantification of the probability of dangerous failure due to random hardware
failures and the generation of documentation associated with every phase of the
complete safety--related lifecycle of the E/E/PES.
