In the Federal Republic of Germany, various national regulations for the
installation in explosive areas must be taken into consideration. The basis for this
forms the working reliability regulation, which is the national conversion of the
European guideline 99/92/E6. They are complemented by the installation regulation
EN 60079-14. The following are excerpts from additional VDE regulations:
