Classification code
The standard provides with the document kind classification code (DCC) a structured letter-code for the classification of any kind of 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.
