Benefits of eCl@ss


  • eCl@ss promotes international interoperability of data exchange in the supply network with a cross-industry product classification systems and standardized interfaces.
  • The work of eCl@ss is for general use and is based on the following main principles:
    • Industry and usage neutral, cross-industry
    • Structured manufacturers and suppliers neutral
    • The market-oriented structure can be used as merchandise codes
    • ISO / IEC / DIN standard-compliant layout and description
    • included in a neutral way languages ​​and country-specific features
  • The voluntary work in the expert groups of eCl@ss is open to all interested parties to participate.


  • Standardized products and services, to find clearly, quickly and safely, with eCl@ss you save time.
  • Article comprising described also for engineering with eCl@ss to save money.
  • eCl@ss Advanced helps to reduce process costs and -duration.

easy data exchange

data quality

  • eCl@ss has rules and regulations defined based on national and international standards:
    • Technical standards for data model and identifications.
    • Naming rules for structural elements.
    • Special rules for structural elements: e.g. classes, attributes, values.
  • Online portal-based workflow process with expert groups to develop and maintain the standard.
  • eCl@ss defined a version process.

global access

  • Online portal-based workflow process with expert groups to develop and maintain the standard.
  • eCl@ss is available in several languages.
  • eCl@ss members have a combined worldwide annual sales of nearly 1,000 billion EUR.


  • The structural elements have a language-independent unique identifier.
  • Whenever possible find the ISO units used.
  • The maintained pivot language is, for the eCl@ss association American English (Language Code: en, Country Code: U.S.). It is the base for all other necessary translations.

master data management

  • eCl@ss supports with its interbranch standard the unification of your own products and supplier products in your IT.
  • The product data classified by the supplier reduce your classification effort and make possible a clearly internal and external communication
  • eCl@ss helps in the analysis of the use with technical data, prices and product descriptions and represents an explicit advantage in competition.

common language

  • The structural elements have a language-independent unique identifier.
  • The original language of the eCl@ss association is American English (Language Code: en, Country Code: U.S.). It is the basis for all other translations.
  • A current eCl@ss main language is German (Language Code: de; Country Code: DE).


  • eCl@ss lives a clearly defined and transparent workflow, based on standard guidelines for development of the standard.
  • Amendments (change requests), any interested free to submit via the eCl@ss-ContentDevelopmentPlatform.
  • The application for new classes and features is just as possible as modifications to existing content.

ISO/IEC konform

  • The data model of the eCl@ss classification system is based, on the structures of the standards DIN 4002, IEC 61360 and ISO 13584.
  • All properties were structured in accordance with DIN 4002.
  • The association maintains relations with the ISO committees TC 37 and TC 184 as well as co-operations:
    • German Institute for Standardization (DIN)
    • European Comité Européen de Normalisation (CEN)
    • German Association for Materials Management, Purchasing & Logistics (BME)
    • German Machinery and Plant Manufacturers (VDMA)

Implementation of eCl@ss

Standardized device data

  • The development and implementation of the required structure was based on typical examples of equipment from the involved manufacturers of the Cross Expert Group CAx.
  • The eCl@ss CAx expert group will continue its efforts standardized data devices from different manufacturers for system developers to provide.
  • At the time the CAx expert group works on a guide to understanding the structures for integrators and data providers.


  • The development of the eCl@ss Advanced structure was done by the ecl@ss CAx expert group comprising representatives of equipment manufacturers and software companies in close cooperation with the eCl@ss center for research and development.
  • The eCl@ss e.V. organized the IT technical requirements including BMEcat 2005.1-advanced.
  • The new structure of the model were introduced by the CAx expert group.
  • At present, the use will be integrated in several CAE tools.

Standard interfaces

  • The German Association Materials Management, Purchasing and Logistics (BME), Frankfurt, has driven the development of a standard (BMEcat) for electronic data transmission for product catalogs.
  • BME and eCl@ss e.V. cooperate and have jointly developed a new "object-oriented" data model. The new BMEcat 2005.1 and eCl@ss 7.1 Specifications support the potential of this new data model in its entirety.
  • This new model was implemented in 2012 to 2005.1 BMEcat-advanced as an extension.
