For the import of equipment for use in potentially explosive atmospheres to Russia and the Eurasian Economic Union (EAEU: Russia, Belarus, Kazakhstan, Armenia and Kyrgyzstan), the explosion-proof equipment (EX equipment) must be certified according to EAEU standards. The EAC EX certification of an explosion-proof electrical or non-electrical device is carried out in accordance with the technical regulations of the Customs Union TR CU 012/2011 On safety of the EX equipment. The certification requires an ignition hazard assessment for explosion-proof equipment.

The ignition hazard assessment confirms that the essential health and safety requirements of the technical regulation are met. The technical regulation was developed in accordance with ATEX Directive 2014/34/EU of the European Parliament and of the Council for the harmonization of the laws of the Member States relating to equipment and protective systems intended for use in potentially explosive atmospheres. The EU and EAEU standards are largely harmonized. However, the ATEX certification does not exempt you from having to certify the equipment to the standards of the Eurasian Economic Union.

The ignition hazard assessment is carried out according to the standards GOST 31441.1-2011 (EN 15198: 2007) and GOST R (EN 15198: 2007), GOST 31441.1 / 2/3/5/6 / 8-2011, GOST 31438.1-2011 (EN 1127-1 : 2007), GOST 31438.2-2011 (EN 1127-2: 2007).

The ignition hazard assessment requires four steps:

  1. analysis of ignition hazards
  2. evaluation of ignition hazards
  3. determination of the necessary measures
  4. final evaluation with determination of the device category

Analysis of ignition hazards

In this step, the ignition hazards and their causes are analyzed. The document lists all potential sources of ignition:

  • hot surfaces of the device
  • open fire in the operating area
  • hot liquids and gases
  • mechanically generated sparks
  • adiabatic compression
  • shock waves
  • exothermic, chemical reactions and thermite welding
  • flammable dusts
  • static electricity

Evaluation of ignition hazards

There is an evaluation, if the potential ignition hazard can become an effective source of ignition and how often this can occur.

Determination of the necessary measures

For each individual ignition hazard identified, appropriate protective measures must be defined depending on the fault conditions to be taken into account and proved with the necessary evidence and technical documentation.

Final evaluation with determination of the device category

In this step, the risk of ignition is compared with protective measures and whether additional protective measures are necessary.
