It contains the following parts: IG EVU-01 Designation and Documentation - part 1: Structuring principles and Reference designation in accordance with IEC 81346 IG EVU-02 Designation and Documentation - part 2: Designation and order of Documentation in accordance with IEC 61355 IG EVU-03 Designation and Documentation - part 3: Planning Tool for Structuring and Designation IG EVU-04 Designation and Documentation - part 4: Examples of Documents in accordance with IEC 6102, IEC 81346 and IEC 61355 This publication series is an application of IEC 81346 and IEC 61355 developed by the German electrical energy transmission companies to create a common standard for technical documentation in German speaking countries. IG EVU-001E: Designation and documentation – Part 1 English translation. 2019-09-18 © IG EVU 2005 – copyright – all rights reserved - 3 - Preface IEC 81346 is the basis for the international classification of objects, and IEC 61355 is the international classification of nomination of documents. (IEC 81346 is the new edition and successor of IEC 61346. Non-electrical interests drove this review. The rules have been altered as little as possible. However, additional letters have been defined for main classes and in particular for subclasses.) The standard is valid for all electrical and non-electrical objects. The benefit of IEC 81346 compared to earlier versions is the efficiency in using the designation principles and will result in less effort. Therefore, the following benefits are noteworthy and will help to improve future documentation: - The classification is applicable for all departments and disciplines and is no longer restricted to electrical engineering. For example, constructive and constructional objects like steel and civil engineering works can easily be integrated in the same classification system. Note: The new standard requires new schematic representation and letter designations because previously only electrical equipment had been considered. - The classification system enables, if properly applied, the integration of any system and components without changing previously defined nomination. - Classification designations are not restricted to a fixed grid (e.g. designation block and data bits). Therefore, the designation system is flexible and expandable in upper and lower directions. Note: This may complicate the interpretation of the reference designation. Therefore, the tree structures used must be documented. - The application of different aspects enables the independent designation (e.g. of functions) regardless of their products (devices) and locations, which implement this function. Note: Until now only the designation of objects and location was possible. The meaning of the prefix has changed because of the new definition in the current version. - By applying IEC 61355, a separation of document designation and object designation for the displayed objects is reached. * - The different aspects (views) enable a state of the art and virtually unlimited structural definition of selection criteria. This can be used, for example, for the automatic generation of documents. Predictably, the user will question the purpose of the specific designation. Many benefits will only become visible during the innovative application of data processing. The goal is to implement the documentation as a resource for specified tasks. IEC 81346 reference designation is a necessary requirement.
