Comité Européen de Normalisation

The European Committee for Standardization, CEN

CEN was founded in 1961 by the national standardization bodies of the member states of EEC and EFTA. It has its headquarters in Brussels (Belgium).

CEN is an officially recognized standardization organization and is responsible for European standards in all technical fields except electrical engineering (here CENELEC is responsible) and telecommunications (here ETSI is responsible). The National Standards Institutes of 34 National Members represent former and current EU member countries, members of the European Free Trade Association (EFTA) and countries that will join the EU or EFTA in the future.

More than 60 0000 experts from various societal interest groups are active in CEN’s working groups.

Besides the secondment of experts from national standards institutes, there are experts with observation status through partner organizations such as Small Business Standards (SBS).

UEG’s membership of SBS also enables it to send experts with observer status to the scaffolding-specific Technical Committee 53 (TC 53).


CEN TC 53 deals with the standardization of temporary structures used for the maintenance and erection of buildings and other temporary structures made of the same components. The products and systems are usually intended for repeated use. Standardization of mechanical engineering systems is not within the scope of the task. The technical committee is chaired by Dr. Robert Hertle. The secretariat is the German Institute for Standardization (DIN).

Below is a list of the existing Working Groups (WGs). The highlighted working groups are currently active.
