The designation ATEX stands for the French abbreviation „Atmosphère explosible“. The term refers to two Directives of the European Union (EU), namely the ATEX Equipment  Directive  94/9/EC  and  the  ATEX  Workplace Directive 1999/92/EG. In Germany, the European ATEX Equipment Directive 94/9/EC is implemented in national law by the Explosion Protection Ordinance (Explosionsschutzverordnung / 11. GPSGV).

AHP Merkle can manufacture hydraulic cylinders according to the ATEX directive. However, the specific application must be considered in detail for this.
