The standard IEC 61355-1 Classification and designation of documents for plants, systems and equipment describes rules and guidelines for the uniform classification and identification of documents based on their characteristic content of information.
It is applied for all documents within the life cycle of a technical products like plants, systems or equipment. It also includes non-technical documents. The main application is the construction, erection and operation of industrial plants where the number of documents of all engineering disciplines may sum up to some 100,000 documents.
During 2024, the new cross-standard ISO/IEC 81355 will be published and will replace the second edition of IEC 61355-1 published in 2008. The new standard will switch from "document classification" to "information classification" methods.
Classification code
The standard provides with the document kind classification code (DCC) a structured letter-code for the classification of any kind of document.
A public access database IEC 61355 DB is available in order to facilitate the individuation of the correct code to be applied to a document
The document kind classification code consists of three code-letters A1, A2, A3, with the prefix "&". A1 Letter code for technical area class A2 Letter code for main class A3 Letter code for sub-class
The letter code A1 is optional, if all documents are from the same technical area. The letter codes A2 and A3 are identical for all technical areas.
Technical Areas The technical areas are:
A1 Technical area A Overall management B Overall technology C Construction engineering E Electrical engineering, instrumentation and control engineering M Mechanical engineering (normally including process engineering)) P Process engineering (only if separation from M is required))
Classes The main classes are:
A2 document kind classes, main classes A Documentation describing documents B Management documents C Contractual and non-technical documents D General technical information documents E Technical requirement and dimensioning documents F Function describing documents LLocation documents MConnection describing documents P Object listings QQuality management documents; safety-describing documents T Geometry-related documents W Operation records
