International standards

National standards also exist in most EU member states, and may be used in these countries in addition to the valid EN standards. In the Federal Republic of Germany, these are the DIN standards and the VDE regulations.

However, extensive harmonization has already been carried out in the explosion protection sector, and most standards now also exist as "DIN EN ...." versions, which have also been incorporated into the VDE regulations. DIN EN standards are identical to the corresponding EN standards, were special national features, e.g. concerning areas of validity etc., are formulated in a national foreword.
