International IECEx Certification: The Way To Safety Compliance In Hazardous Areas

Faster Access To Markets - Improved Safety

IECEx Certificate of ConformityThe IECEx is a multilateral conformity assessment system based on IEC standards that offers a single international Ex test report (ExTR) for acceptance in all participating countries-eliminating the need for duplicate testing. These IECEx System ExTRs can be taken to any of the participating countries to obtain certification to whatever the applicable requirements may be -- whether local, regional, or global. For the hazardous locations market, 30 countries across Asia-Pacific, Europe and North America are accepting these IECEx System ExTRs for in-country certification. Learn more » About the IECEx

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 refueling stations or petrol stations
  • Oil refineries, rigs and processing plants
  • Chemical processing plants
  • Printing industries, paper and textiles
  • Hospital operating theatres
  • Aircraft refueling 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 aluminum dusts and particles

IECEx Rules

The administration of the IECEx System is governed by the IECEx Rules:

  • IECEx 01: IEC System for Certification to Standards relating to Equipment for use in Explosive Atmospheres (IECEx System)-Basic Rules
  • IECEx 02: IEC System for Certification to Standards relating to Equipment for use in Explosive Atmospheres (IECEx System), IECEx Certified Equipment Scheme covering equipment for use in explosive atmospheres – Rules of Procedure
  • IECEx 03-2: IECEx Certified Service Facilities Scheme-Part 2: Selection of Ex equipment and design of Ex installations-Rules of Procedure
  • IECEx 03-3: IECEx Certified Service Facilities Scheme-Part 3: Ex installation and initial inspection – Rules of Procedure
  • IECEx 03-4: IECEx Certified Service Facilities Scheme-Part 4: Ex inspection and maintenance-Rules of Procedure
  • IECEx 03-5: IECEx Certified Service Facilities Scheme-Part 5: Repair, overhaul and reclamation of Ex equipment-Rules of Procedure
  • IECEx 04: IEC Scheme for Certification to Standards relating to Equipment for use in Explosive Atmospheres (IECEx Scheme)-IECEx Conformity Mark Licensing System-Regulations
  • IECEx 05: IEC System for Certification to Standards relating to Equipment for use in Explosive Atmospheres (IECEx System), IECEx Scheme for Certification of Personnel Competence for Explosive Atmospheres-Rules of Procedure
