TS EN 61666
Industrial systems, installations and equipment and industrial products - Identification of terminals within a system
This International Standard establishes general principles for the identification of terminals of
objects within a system, applicable to all technical areas (for example mechanical
engineering, electrical engineering, construction engineering, process engineering). They can
be used for systems based on different technologies or for systems combining several
technologies.
Requirements for marking of terminal designations on products are not part of this publication.
NOTE The standard is based on the general principles for the structuring of systems including structuring of the
information about systems, established in the International Standard ISO/IEC 81346 series, published jointly by
IEC and ISO.

About This Item
TS EN 61666 addresses the general principles for identifying terminals within a system. Its focus is not the physical marking of terminal designations on products, but the consistent and unambiguous designation of terminals as part of the system structure. In practice, this helps reduce ambiguity where several disciplines must work from the same technical documentation and reference scheme.
The standard provides a framework that can be applied across all technical areas, including mechanical engineering, electrical engineering, construction engineering and process engineering. It is also suitable for systems based on different technologies as well as systems combining several technologies. In that sense, the document is about structural identification within a system rather than a product-specific terminology for one industry only.
How terminal identification fits into system structuring
In general technical usage, a terminal is a point where a connection ends, is terminated, or interfaces with another part of the system, such as a conductor end, connection point, or subsystem interface. Clear terminal identification helps keep drawings, parts lists, maintenance records and installation documents aligned. TS EN 61666 supports this by setting out general principles for how such identification should be organised within the overall system structure, in line with the system-structuring approach of the ISO/IEC 81346 series.
