ATEX Testing & Certification
European ATEX Directive 2014/34/EU
Electrical and non-electrical equipment for use in workplaces potentially at risk for explosive atmospheres must ensure a level of safety appropriate to the area of installation.
In Europe this is enforced through the ATEX Directive 2014/34/EU. In addition to CE Marking, equipment used in explosive atmospheres must also gain the Ex Mark which requires accredited testing, Notified Body certifications.
Products included in the scope of the ATEX Directive 2014/34/EU include:
- Equipment and Protective Systems which may be used in potentially explosive atmospheres
- Safety devices, controlling devices and regulating devices intended for use outside potentially explosive atmospheres but which are required for or contribute to the safe functioning of equipment and protective systems, with respect to the risks of explosion
- Components defined as any item essential to the safe functioning of equipment and protective systems but with no autonomous function
There are three steps to being able to gain ATEX certification from an ATEX Notified Body:
- Compliance with the applicable CE marking IEC/EN product standards
- Compliance with the ATEX Ex general standards for products going into explosive atmospheres
- Compliance with one specific type of protection method described in the ATEX specific standards
How we can help
The design requirements for products used in an explosive atmosphere differ significantly from those employed in a non-explosive atmosphere. Furthermore, there are key design differences depending on which type of explosive atmosphere they may be used in. It is therefore imperative to understand the what the design implications are at the start of the product design process.
We can help you at each step of the ATEX compliance process to ensure that the correct assumptions and decisions have been made, test your products and provide you with the appropriate certifications.
