| ISO | IEC 81346 |
The standard EN 81346 Industrial Systems, Plants and Equipment and Industrial Products - Structuring Principles and Reference Marking shows ways to structure information about systems and to create reference marks (formerly: equipment marks). It is also published as a DIN standard . The standard used to be listed as EN 61346 or IEC 61346 , with the new edition in May 2010 the number was renumbered to EN 81346 and IEC 81346 .
structure
The standard consists of two parts and two supplementary sheets:
- EN 81346-1: General rules (IEC 81346-1: 2009)
- EN 81346-2: Classification of objects and coding of classes (IEC 81346-2: 2009)
The application guidelines (IEC / TR 61346-3: 2001) and considerations of terms and their relationships (IEC 61346-4: 1998) to DIN EN 61346 were withdrawn in May 2010 without replacement.
They are translations of the international standard IEC 81346 published by the IEC . In 1997, the IEC changed the numbering of the IEC publications and added 60000 to the standard numbers used until 1997. For example, IEC 61346 from 1996 was published under the number IEC 1346, but was listed under IEC 61346.
From 2010, the standards for reference identification will be published as a common IEC / ISO standard in the 80000 number range and then published under the number 81346.
scope of application
Within the lifecycle of industrial plants and systems, a uniform reference identification system is required for planning, design, implementation, operation, maintenance and dismantling in order to be able to clearly identify all objects within the system at any time.
The scope of the standard goes beyond the purely electrotechnical area, with the aim of describing technical systems as a whole. Objects without electrotechnical relevance (e.g. mechanical elements) are taken into account in the same way as typical electrotechnical objects (e.g. fuses, switches).
EN 81346-1
The first part shows how you can proceed with structuring. Examples of structuring criteria, called "aspects", are shown. However, it is also possible to use other criteria that are not mentioned. The structure obtained should allow easy embedding in a higher-level system.
One of the strengths of the concept of "aspect objects" defined in the standard is that objects can be arranged in different hierarchies at the same time and the object identity is still guaranteed. Typically, a system is broken down under the functional aspect as well as the structural or product component aspect. Another useful aspect could be the spatial position of the components. A component that has to fulfill two different functions f1 and f2, for example, would therefore be assigned four aspects: One for the position within the product component hierarchy, one for the installation position and one each for the functions f1 and f2. Computer-aided modeling tools that implement the concept of “aspect objects” ensure that object identity is preserved, regardless of the hierarchy from which the “object occurrence” is accessed.
The specifications of the standard are kept very general in order to cover a wide range of applications. The terms used are abstract and are defined as follows:
| term | meaning |
|---|---|
| object | Consideration unit that is dealt with in a construction, planning, implementation, operation, maintenance and dismantling process |
| aspect | Specific way of looking at selecting information about a system or selecting a system or an object of a system |
| structure | Organization of relationships between objects of a system, which describes a component-of-relationship (consists of / is part of) |
| Reference number | Unique identification of a specific object in relation to the system of which the object is part. It is based on the aspects of the system. |
The standard distinguishes between three different aspects (ways of looking at objects).
- What is the system or the object doing? (Functional aspect)
- How is the system or the object composed? (Product aspect)
- Where is the system or the object located? (Location aspect)
With regard to these three aspects, the standard describes the corresponding structures:
- Function-related structure
- Product-related structure
- Location-based structure
The standard defines the following signs for the identification of the aspects to which a reference label relates:
| sign | Aspect type of the reference identifier |
|---|---|
| = | if it relates to functional aspects of an object |
| - | if it relates to product aspects of an object |
| + | when it relates to the location aspects of an object |
EN 81346-2
The second part shows how objects are classified and which code letters are to be used. The code letters apply to both mechanical and electrical objects.
In EN 81346-2 the identification letters of the main classes for the purpose and task of objects are specified. In addition, the code letters for subclasses have been adopted from the withdrawn DIN 6779-2 . In contrast to DIN 40719-2 from 1978, the code letters describe the function instead of the type of component.

Application of the standard
The standard has so far been implemented only slowly, although it offers significant advantages over the previous standard IEC 750. One of the reasons for this is that the previous fixed assignment of the code letters to device types (F for fuse, K for contactor, Q for circuit breaker, etc.) has been changed and the same devices could therefore have different code letters depending on their function (F for automatic circuit breaker as line protection, Q for automatic circuit breaker as circuit breaker).
With CAx systems, this means that the code letters for symbols can no longer be permanently assigned.
The standard is the basic standard for other standards that are based on the principles of the standard and specify them for special applications:
- ISO / TS 16952-1 (Technical Product Documentation - Reference Identification System - General Application Rules) defines rules for the identification of technical objects, connections, signals and their documents.
- The RDS-PP (Reference Designation System for Power Plants) defines proposals for a labeling similar to EN 81346, while retaining the KKS codes, for power plants.
- In the VDMA standard sheet 34191 "Code letters for subclasses of objects for use for reference marking on machine tools", typical components of a machine tool are uniformly identified in accordance with EN 81346.
- in the system identification regulation for the national roads in Switzerland (AKS-CH). Since 2009, FEDRO has defined the product aspect of the labeling of these systems and derived the location aspect from EN 81346-2009. It also relies on the spatial base reference system (RBBS) for the national roads.
