Series of standards EN 61508 (VDE 0803)

This series of standards describes the current state of the art.
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. The manufacturer of a safety-related product, however, can also use EN 61508 to
fulfill basic requirements of European directives in accordance with the latest conceptual
design, for example, in the following cases:
● If no harmonized standard exists for the application in question. In this case, the
● A harmonized European standard (e.g. EN 62061, EN ISO 13849, EN 60204-1)
EN 61508 covers all the aspects that must be taken into account when E/E/PES systems
(electrical, electronic, and programmable electronic System) are used in order to execute
safety functions and/or to ensure the appropriate level of functional safety. Other hazards
(e.g. electric shock) are, as in EN ISO 13849, not part of the standard.
EN 61508 has recently been declared the "International Basic Safety Publication", 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 stipulate it (e.g. as a basis for NRTL listing).
Another recent development with respect to EN 61508 is its system approach, which extends
the technical requirements to include the entire safety installation from the sensor to the
actuator, the quantification of the probability of hazardous failure due to random hardware
failures, and the creation of documentation covering all phases of the safety-related lifecycle
of the E/E/PES.

references EN 61508. This ensures that the appropriate requirements of the directives
are fulfilled ("standard that is also applicable"). When manufacturers apply EN 61508
properly and responsibly in accordance with this reference, they can use the presumption
of conformity of the referencing standard.
