The ATEX directive consists of two EU directives which describe the minimum safety requirements of the workplace and equipment used in explosive atmosphere. Like all EU Directives, the ATEX Directive generally relies on the application of relevant standards to assess technical compliance. Compliance with the technical requirements of EU harmonised standards provides a presumption of conformity with the Directive’s essential requirements. In cases where relevant harmonised standards do not exist, manufacturers are required to apply other EU standards, or applicable national or international standards. In rare cases, where a particular product is not covered by any existing standard, a manufacturer is required to complete a thorough evaluation of the product to demonstrate compliance.
