ATEX Compliance of Mechanical Equipment

August 13, 2017

ATEX Manufacturers Directive 94/9/EC  defines the applicability of each of the following product groups for use in potentially explosive atmospheres:

  • Electrical and non-electrical equipment

Electrical and non-electrical “equipment” capable of igniting the explosive atmosphere under   normal or fault conditions are covered under this directive.

  • Electrical and non-electrical protective systems

Separately supplied protective systems for fitting to equipment to control unavoidable explosions such as explosion vents, suppression systems etc. are covered under this directive.

  • Electrical and non-electrical components

Components (items essential to the safe functioning of equipment and protective systems but with no autonomous function) such as electrical components etc. are covered under this directive.

  • Electrical and non-electrical safety devices

Safety devices, controlling devices and regulating devices contributing to the safe functioning of equipment and protective systems such as gas detection systems that de-energize equipment are covered under this directive.

By above definition, many non-electrical equipment or mechanical equipment particularly those which have moving components/parts are covered under the category requiring ATEX approval. However the rules for ATEX compliance of non-electrical equipment/ mechanical equipment differ to those of electrical equipment. Whilst such mechanical devices still need to “comply” with  ATEX Directive however in most  of such cases  the Self Certification of the manufacturer  is sufficient and  as such it’s not always required to obtain a certificate from a Notified Body except those devices which are required to be installed in Zone 0 (Category 1 equipment)
