“IEC1355” is the popular name of the IEC61355-1 standard.

 

“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 technical products like plants, systems or equipment. It also includes non-technical documents. The main application is the construction, erection and operation of chemical plants and power plants, where the number of documents may sum up to some 100,000 documents.

 

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.”
