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组织目标

     IECEx组织的目标是促进在爆炸性环境中使用的设备和服务的国际贸易,同时保持所需的安全水平:

•降低制造商的测试和认证成本 

•缩短上市时间 

•对产品评估过程的国际信心

 •一个国际数据库列表

•对IECEx认证所涵盖的设备和服务保持国际信心

 

什么是危险区域?

     防爆区可以用不同的名称来命名,例如“危险场所”、“危险区域”、“爆炸性环境”等,并且与易燃液体、蒸汽、气体或可燃粉尘的数量可能足以引起火灾或爆炸的区域有关。现代工业的自动化意味着越来越需要在防爆区使用设备。这种设备被称为“防爆设备”。你通常在哪里找到防爆设备?此类区域的防爆设备包括:

•汽车加油站或加油站

•炼油厂、钻机和加工厂

•化学加工厂

•印刷业、纸张和纺织品

•医院手术室

飞机加油和机库

•表面涂层行业

•地下煤矿

•污水处理厂

•输气管道和配气中心

•谷物装卸和储存

•木工区

•制糖厂

•金属表面研磨,尤其是铝粉尘和颗粒

 

IECEx国际认证体系

      除了制定国际标准外,国际电工委员会还促进了合格评定体系的运行。其中一个系统是IECEx系统。IECEx系统包括:

•IECEx认证设备方案

•IECEx认证服务设施方案

•IECEx一致性标志许可制度

•IECEx人员能力认证(COPC)
