VDE - German association for electrotechnics, electronics and information technologies was founded as early as 1893. It supports modern education for professionals and high acceptance by people. It supports development of electrotechnics, electronics and information technologies and related technologies.
The main task of the association lies in safety in electrotechnics, elaboration of respected technical rules such as national and international standards, tests and certification of equipment and systems.
American version of VDE standards is marked as UL standard (Underwriters Laboratories).
