Subject to certain safeguards, products bearing the ‘CE’ mark are permitted to be sold throughout the EU  
without interference from national regulatory authorities. The Directives have been put in place in order to  
remove artificial trade barriers within the European Union previously caused by individual countries’ national  
standards, a secondary function is as a means of regulating safety.

The Directive applies to all equipment and systems for use in potentially explosive atmospheres within the EU.  
The scope of the Directive includes electrical and mechanical equipment for use in Group I (mining) or Group II  
(industrial) applications, both on and offshore and considers risks of ignition of potentially explosive gas, vapour,  
mist and dust atmospheres. In addition, devices intended for use outside potentially explosive atmospheres that  
contribute to the safe functioning of equipment and systems with regard to explosion risk are also included.

Compliance of products to the ATEX Equipment Directive, through conformity assessment, takes a modular  
approach, and is generally in two stages; design and production.  
Increased  
safety  
Ex e  
design excludes  
the possibility of  
incendive arcs, sparks  
or hot surfaces  
2
A common route to product design compliance is to apply to a Notified Body (Ex. Test House) for an EC  
Type Examination Certificate. To comply, the equipment or system must meet the Essential Health and Safety  
Requirements (EHSRs) listed in the Directive. Harmonised EU standards have been adopted by CENELEC and  
CEN, relating to the design, construction and testing of equipment; a product complying with these standards  
is deemed to meet the EHSRs to which the standards relate. Where apparatus follows a protection concept  
not covered by these standards, compliance to the 94/9/EC Directive is still possible by compiling a ‘Technical  
File’ from first principles, demonstrating compliance through test and assessment to the EHSRs relating to  
design and construction of equipment for use in explosive atmospheres.

The production quality stage of the conformity assessment procedures ensure continued product compliance  
in manufacturing. Typically a manufacturer should have a certified ISO 9000 quality management system and  
comply with one of the quality modules in the ATEX Equipment Directive, however this will vary depending on  
product equipment category; equipment used in higher risk areas will require more onerous conformity  
assessment procedures to be applied.

In addition to the 94/9/EC ATEX (Equipment) Directive, products for use in potentially explosive atmospheres  
may require to be compliant with other Directives including the 89/336/EEC Electro-Magnetic Compatibility  
(EMC) Directive, which became mandatory on 1/1/96. This Directive applies to virtually all electrical and  
electronic apparatus potentially able to generate interfering emissions or exhibit an undue sensitivity to

It lists a set of obligations and safety measures for employers, requiring the adoption of a coherent risk  
assessment based strategy for the prevention of explosions. These obligations include:  
Generation of an explosion protection document, evaluating explosion risk, including: likelihood of the  
presence of the explosive atmosphere, the presence of ignition sources (including electrostatic discharge),  
identification of the substances and processes in use, definition of specific measures taken to safeguard  
the health and safety of workers.
