ATEX equipment certification

ATEX motor

The European Directive 2014/34/EU, also known as ATEX 114, includes the requirements for devices and protective systems that are intended for use in Explosives Atmospheres.

According to the requirements of this Directive, electrical equipment intended to be installed in Zone 0 or 1, shall be certified from a Notified Body. The Notified Body is responsible to:

  1. Examine and evaluate the conformity of the submitted Technical File of the product
  2. Conduct the required tests in an accredited laboratory
  3. Assess the quality system of the production process as provided by the corresponding paragraphs of the directive in order to assign the "Ex" designation to the product and the corresponding explosion protection class

Regarding electrical equipment intended to be installed in Hazardous Areas classified as Zone 2, the directive requires the creation of a Technical Compliance Documentation File for the explosion protection product and internal production control.  

Regarding non-electrical equipment intended to be installed in Hazardous Areas classified as ‘’Zone 0’’, similarly as for electrical equipment, the following are required: submission of the Technical Compliance Documentation File to a Notified Body for examination and evaluation, implementation of the required tests by the Notified Body and examination of the production quality system.

Regarding ‘’Zone 1’’ non-electrical equipment, it is necessary to submit the technical file for safekeeping to a Notified Body, while for "Zone 2" non-electrical equipment only the compilation and safekeeping of the Technical File by the manufacturer is required.

Regarding ATEX equipment of all Groups and Categories that belong to the «Unit Verification scheme», the involvement of the Notified body into the certification procedure is necessary (Annex IV of the ATEX Directive)
