## What is RDS 81346?

The RDS 81346 app helps you to easily look up classification codes to be used in reference designations for technical systems and their documentation, based on the ISO/IEC 81346 standard series for Reference Designation Systems (RDS) for systems and the IEC 61355 standard for classification of documents.

You can easily find the proper classification by searching either for letter codes, definitions or technical terms. You can also quickly find your most recently used classification.

Examples of common terms from the standards and industry are available for all classes, making it possible to simply search for the name of an object you want to classify and find the proper class.
