TS EN IEC 81355-1
Industrial systems, installations and equipment and industrial products - Classification and designation of information - Part 1: Basic rules and classification of information
IEC 81355-1:2024 provides rules and guidelines for the classification and designation of information containers based on their inherent content. This document is applicable for information used in the life cycle of a system, e.g., industrial plants, construction entities and equipment. This document defines classes of information and their information kind classification code (ICC). The defined classes and codes provided are used as values associated with metadata, e.g., in information management systems (see IEC 82045-1 and IEC 82045-2). The rules, guidelines and classes are general and are applicable to all technical areas, for example, mechanical engineering, electrical engineering, construction engineering and process engineering. They can be used for systems based on different technologies or for systems combining several technologies. This document also has the status of a horizontal publication in accordance with IEC Guide 108. It is intended for use by technical committees in preparation of publications related to classification and designation of information. IEC 81355-1:2024 cancels and replaces the second edition of IEC 61355-1 published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 61355-1:2008: a) focusing on classification of information rather that classification of document kinds; b) introduced a classification scheme based on inherent content of information; c) introduced a distinction between an information container and a document, the latter being for human perception; d) introduction of information kind classification code (ICC), replacing document kind classification code (DCC); e) introduced structuring of information containers; f) introduced an information model of the concepts dealt with; g) introduced a conversion table for merging from the use of DCC to the use of ICC.

About This Item
TS EN IEC 81355-1 is a foundational horizontal standard for classifying and designating information in industrial systems, installations, equipment and other industrial products. Its focus is the meaning carried by the information itself rather than the carrier, providing rules for how information kinds are grouped and how those groups are represented in metadata.
Information kinds and the ICC approach
The standard distinguishes between an information container and the information content it carries. In general technical terms, this means a drawing, record, data set or other information object is classified by its inherent content, not merely by its format. The document defines information classes and the corresponding information kind classification code (ICC), intended for use as metadata values in information management systems. This supports consistent classification across domains and across different kinds of technical documentation.
A common framework across technical disciplines
The rules are stated as general and applicable to multiple technical areas, including mechanical engineering, electrical engineering, construction engineering and process engineering. That breadth matters in mixed-technology systems, where consistent information designation helps maintain traceability and order over the asset life cycle. In this edition, the standard shifts the emphasis from classifying document kinds to classifying information by inherent content, and it replaces the former document kind classification code (DCC) with ICC. It also introduces structuring concepts, an information model and a conversion table to support transition from DCC-based use.
