Verification Dossier

Additionally, IMS can assist in achieving a compliant Verification Dossier for your DSEAR Areas and ATEX Installations.

This dossier is a set of documents showing the compliance of electrical equipment and installations in hazardous areas. BSEN 60079-14 states that a verification dossier shall be prepared for every installation to correctly install or extend an existing installation.

The following information is additional to that required for non-hazardous areas and is required as part of the verification dossier where applicable:


  • Area classification documents (see IEC 60079-10-1 and IEC 60079-10-2) with plans showing the classification and extent of the hazardous areas including the zoning (and maximum permissible dust layer thickness if the hazard is due to dust);
  • Optional assessment of consequences of ignition;
  • Where applicable, gas, vapour, or dust classification in relation to the group or subgroup of the electrical equipment;
  • Temperature class or ignition temperature of the gas or vapour involved;
  • Where applicable, the material characteristics including electrical resistivity, the minimum ignition temperature of the dust cloud, minimum ignition temperature of the dust layer and minimum ignition energy of the dust cloud;
  • External influences and ambient temperature.


  • Manufacturer’s instructions for selection, installation, and initial inspection;
  • Documents for electrical equipment with conditions of use, e.g. for equipment with certificate numbers which have the suffix “X”;
  • Descriptive system document for the intrinsically safe system;
  • Details of any relevant calculation, e.g. for purging rates for instruments or analyser houses;
  • Manufacturer’s/qualified person’s declaration. Consideration should be given to obtaining information for maintenance and repair to meet the requirements of IEC 60079-17 and IEC 60079-19 respectively.


  • Necessary information to ensure correct installation of the equipment provided in a form which is suitable to the personnel responsible for this activity;
  • Documentation relating to the suitability of the equipment for the area and environment to which it will be exposed, e.g. temperature ratings, type of protection, IP rating, corrosion resistance;
  • Plans showing types and details of wiring systems;
  • Records of selection criteria for cable entry systems for compliance with the requirements for the particular type of protection;
  • Drawings and schedules relating to circuit identification;
  • Records of the initial inspection;
  • Installer’s/qualified person’s declaration
