电子电器产品CE-EMC认证

EMC(电磁兼容性)的全称是Electro Magnetic Compatibility， 其定义为“设备和系统在其电磁环境中能正常工作且不对环境中任何事物构成不能承受的电磁骚扰的能力” 该定义包含两个方面的意思，首先，该设备应能在一定的电磁环境下正常工作， 即该设备应具备一定的电磁抗扰度(EMS); 其次，该设备自身产生的电磁骚扰不能对其他电子产品产生过大的影响，即电磁骚扰(EMI)。电磁兼容性认证几乎是所有带电产品进行欧盟CE认证都需要进行的认证标准。这也是电，磁互生关系造成的结果，因此几乎所有具备电路板的通电产品都会随着电路的流通产生磁场，而欧盟为了这类产品产生的磁场不会对自身以及周围的人和事物产品影响，所以在1989年5月3日在官方公报上颁布了一项89/336/EEC指令，即EMC指令。从1996年1月1日起， 所有投放欧盟市场的电气或电子器具、设备均需符合EMC指令的要求， 否则不准进入欧盟市场。2007年7月20日，EMC指令2004/108/EC替代89/336/EEC发布；2016年4月20日，新EMC指令2014/30/EU开始代替2004/108/EC作为现行最新指令，销往欧盟的产品，对于适用于本指令设备满足其要求是强制的，并且满足本指令时要加贴 CE标识。EMC 指令中规定，各成员国不得以电磁兼容为由，阻碍满足本指令要求的设备在本国投放市场和投放使用。

The full name of EMC(electromagnetic Compatibility) is Electro Magnetic Compatibility, which is defined as "the ability of equipment and systems to work normally in their electromagnetic environment and not to constitute an unbearable electromagnetic harassment of anything in the environment." The definition contains two aspects of meaning, first, The equipment should be able to work normally in a certain electromagnetic environment, that is, the equipment should have a certain electromagnetic immunity (EMS); Secondly, the electromagnetic harassment generated by the device itself cannot have an excessive impact on other electronic products, that is, electromagnetic harassment (EMI). Electromagnetic compatibility certification is the certification standard that almost all live products need to carry out the EU CE certification. This is also the result of electrical and magnetic mutuality, so almost all powered products with circuit boards will generate magnetic fields with the circulation of the circuit, and the European Union in order to produce such products will not have a magnetic field on their own and the surrounding people and things products, so on May 3, 1989 in the official Gazette issued an 89/336/EEC directive. The EMC Directive. Since January 1, 1996, all electrical or electronic appliances and equipment placed on the EU market must meet the requirements of the EMC Directive, otherwise they are not allowed to enter the EU market. On July 20, 2007, EMC Directive 2004/108/EC was issued to replace 89/336/EEC. On April 20, 2016, the new EMC Directive 2014/30/EU began to replace 2004/108/EC as the current latest directive, and products sold to the EU are mandatory for equipment applicable to this directive to meet its requirements, and to meet this directive to attach the CE mark. According to the EMC Directive, member States shall not use electromagnetic compatibility as an excuse to prevent equipment meeting the requirements of this directive from being placed on the market and put into use in their own countries.
