The IEC Common Data Dictionary (CDD) is a registry for metadata used for classification and description of products in all industrial/technical domains.
The data model is described in IEC 61360. The dictionary includes quantities and units that are described in IEC 62720 - Identification of units of measurement for computer-based processing.
It covers any standard or non-standard units of measure currently in use, in two or more distinct ethno-linguistic groups or nations, at least in one domain of industry, for which an explicit method of conversion to a known standard unit of measure or its equivalent is well documented or evident from external references.
