ECLASS (formerly styled as eCl@ss) is a classification system for products and services. It is maintained by industry consortium ECLASS e.V. association.
The ECLASS classification system is based on a hierarchical grouping of products and services. There are 4 levels of hierarchy:
* Segments,
* Main group,
* Group,
* Sub-group or product class.
This classification provides a grouping from point of view of purchasing.
A product class has a 1:1-relation to an application class. Application classes are described in further details with properties according IEC 61360. This approach separates the definition of the classification hierarchy from the definition of the product descriptions.
