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)
IECEx組織目標
IECEx組織的目標是促進在爆炸性環境中使用的設備和服務的國際貿易，同時保持所需的安全水平：
•降低制造商的測試和認證成本
•縮短上市時間
•對產品評估過程的國際信心
•一個國際數據庫列表
•對IECEx認證所涵蓋的設備和服務保持國際信心
什么是危險區域？
防爆區可以用不同的名稱來命名，例如“危險場所”、“危險區域”、“爆炸性環境”等，并且與易燃液體、蒸汽、氣體或可燃粉塵的數量可能足以引起火災或爆炸的區域有關。現代工業的自動化意味著越來越需要在防爆區使用設備。這種設備被稱為“防爆設備”。你通常在哪里找到防爆設備？此類區域的防爆設備包括：
•汽車加油站或加油站
•煉油廠、鉆機和加工廠
•化學加工廠
•印刷業、紙張和紡織品
•醫院手術室
飛機加油和機庫
•表面涂層行業
•地下煤礦
•污水處理廠
•輸氣管道和配氣中心
•谷物裝卸和儲存
•木工區
•制糖廠
•金屬表面研磨，尤其是鋁粉塵和顆粒
IECEx國際認證體系
除了制定國際標準外，國際電工委員會還促進了合格評定體系的運行。其中一個系統是IECEx系統。IECEx系統包括：
•IECEx認證設備方案
•IECEx認證服務設施方案
•IECEx一致性標志許可制度
•IECEx人員能力認證（COPC）
