Structure and structural elements

ECLASS is a system for classification and product description. It consists of different structural elements who are in a certain relation with each other.

The relations of the BASIC and the ADVANCED versions are described here.

The translation of the structural elements can be found here.

List of structural elements

ECLASS consists of the following structural elements (SE):

Type of SE Abbreviation of SE Definition of SE Type of SE Code Exists in BASIC Exists in ADVANCED
Classification Class CC A product group identified by a preferred name and an eight-digit coded name that represents the four-level classification structure 01 Yes Yes
Property PR A characteristic of a class 02 Yes Yes
Value VA A specification of a characteristic 07 Yes Yes
Unit UN Standardized unit of measure 05 Yes Yes
Keyword KW An alternative name of a class Z5 Yes Yes
Synonym SY An alternative name of a property Z6 Yes Yes
Value List VL A restrictive list of valid specifications of a property 09 Yes Yes
Application Class AC Class that comprises all characteristics described by properties 01 No Yes
Aspect AS Sub-class of an application class that comprises all properties describing a certain aspect of a product, not the product itself, e.g. packing information 01 No Yes
Block BL Sub-class of an application class that comprises all properties describing a certain part of a product 01 No Yes
Reference Property RP Property that references a block 02 No Yes
...       No Yes

ECLASS structure

ECLASS consists of a four-level hierarchy of classification classes (see class structure).

The fourth level, the commodity class or product group is then further described with the help of properties and property values. Properties and values form the basis for the product description. See also figures 1 and 2 for an example:


Figure 1: the ECLASS tree structure.



Figure 2: Example of the ECLASS tree structure.


With ECLASS 7.0 a BASIC and an ADVANCED version were distinguished for the first time. In order to implement this, two different Application Classes were established: a BASIC Application Class and an ADVANCED Application Class.

In the BASIC Version only the BASIC Application Class is available. But it is not visible to the BASIC user, as to every Classification Class exactly one Application Class is assigned that contains all properties to describe the product class.

In the ADVANCED version an optional ADVANCED Application Class might be additionally assigned to the Classification Class. As this is relevant for the ADVANCED user, both BASIC Application Class (mandatory) and an additional ADVANCED Application Class (optional) are part of the ADVANCED version.

The following figure shows two Application Classes for one Classification Class. In the ADVANCED Application Class, a Reference Property opens a Block that consists of descriptive properties.
