Frequently Asked Questions
An EU Directive is a legislative act of the European Union that sets out goals that all EU member states must achieve. However, it is up to each member state to devise their own laws on how to reach these goals through national transposition. Directives are used to harmonize laws across the EU, particularly for the functioning of the single market.
Directive 97/53/EC covers "Electrical apparatus for use in explosive atmospheres using certain modes of protection". There are 26 standards associated with this directive.
Harmonized standards under 97/53/EC are European standards (ENs) developed by CEN, CENELEC, or ETSI in response to a mandate from the European Commission. When these standards are cited in the Official Journal of the European Union, products manufactured in conformity with them benefit from a presumption of conformity with the essential requirements of 97/53/EC, facilitating CE marking and free movement within the European Economic Area.
