IEC 61355

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.
