IECEx System Objective

The objective of the IECEx System is to facilitate international trade in equipment and services for use in explosive atmospheres, while maintaining the required level of safety:

  • reduced testing and certification costs to manufacturer
  • reduced time to market
  • international confidence in the product assessment process
  • one international database listing
  • maintaining International Confidence in equipment and services covered by IECEx Certification

What is an Ex area?

Ex areas can be known by different names such as “Hazardous Locations”, “Hazardous Areas” “Explosive Atmospheres”, and the like and relate to areas where flammable liquids, vapours, gases or combustible dusts are likely to occur in quantities sufficient to cause a fire or explosion.

The modern day automation of industry has meant an increased need to use equipment in Ex areas. Such equipment is termed “Ex equipment”

Where do you commonly find Ex equipment?

Ex equipment in such areas include:

  • Automotive refuelling stations or petrol stations
  • Oil refineries, rigs and processing plants
  • Chemical processing plants
  • Printing industries, paper and textiles
  • Hospital operating theatres
  • Aircraft refuelling and hangars
  • Surface coating industries
  • Underground coalmines
  • Sewerage treatment plants
  • Gas pipelines and distribution centers
  • Grain handling and storage
  • Woodworking areas
  • Sugar refineries
  • Metal surface grinding, especially aluminium dusts and particles

IECEx International Certification System

In addition to the preparation of International Standards, the IEC facilitates the operation of Conformity Assessment Systems. One such System is the IECEx System.

The IECEx System comprises the following:

  • The IECEx Certified Equipment Scheme
  • The IECEx Certified Service Facilities Scheme
  • The IECEx Conformity Mark Licensing System
  • The IECEx Certification of Personnel Competencies (CoPC)

Informative Guideline for national officials for regulation

Explosion protection is an essential part of the overall risk management to be conducted for industrial sectors such as coal mining, oil, gas and chemical industries, to ensure safety in industrial processes using or producing hazardous materials like – for example – combustible gas, dusts or vapours. The risks to life and health of persons and the risk of loss of property when using the equipment which operates in the presence of explosive atmospheres are high.

Equipment used in high-risk facilities is highly sophisticated. Checking that it conforms to international best practice and current regulations is a complex task, even for those regulatory authorities who have substantial resources and modern equipment at their disposal.

Most national regulatory frameworks require that conformity assessment be conducted by independent, third-party inspection bodies. This is a prerequisite for safety in a sector where hazards are substantial and may involve many casualties. The IECEx Certification System offers a global framework for equipment, repair facilities or personal competence in this field.

Invitation to communicate and exchange of information with the IECEx-System
The IECEx system sees themselves as a transparent organisation with the aim to have a high safety level an interaction with national officials for regulation is essential in cases of e.g. non-compliance matters. In case of non-compliance matters the IECEx-System appreciates to be contacted by national officials for regulation in the Ex-field. One of the unique and key features of the IECEx is the IECEx “On-Line” Certificate System with full public display of all IECEx Certificates, which provides a one-stop location that provides instant verification and checking of claims of holding IECEx Certification for either Ex Products, Ex related Service Organisations and Persons certified as Competent in the Ex field. For further information our contact is:

The IECEx system offers high confidentiality with respect to non-compliance or also general technical matters. The secretariat in conjunction with a steering committee of IECEx can handle your concerns.

The IECEx System appreciates your trust and support by starting the communication and discussion to get a highly recognized certification system.
