The standard IEC 61355-1 Classification and designation of documents for plants, systems and equipment describes rules and guidelines for the uniform
classification

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:
Classes
The main classes are:
