The European Community government stipulates that starting from January 1, 1996, all electrical and electronic products must pass EMC certification. Electromagnetic compatibility (EMC) refers to the ability of equipment or systems to operate in their electromagnetic environment in compliance with requirements without causing adverse electromagnetic interference to any other equipment in their environment. It involves various products such as electronics, motors, information, communication, etc. With the widespread application of these products in various fields, in addition to users' quality requirements for electromagnetic compatibility, governments of various countries are also actively formulating relevant control standards and specifications The scope of EMC certification for electromagnetic compatibility is in accordance with Article 2.1 of the Directive, which applies to all devices that are prone to electromagnetic interference or whose functions are susceptible to electromagnetic interference. Instruments listed in the vicinity of the EMC directive The equipment is as follows: household radio and television receivers, industrial manufacturing equipment, mobile radios, mobile radios, and commercial mobile phones, medical and scientific equipment, information technology equipment, general electrical and household appliances, aviation and marine wireless equipment, educational electronic equipment, telecommunications networks and instruments, medical and scientific equipment, lighting and fluorescent lights, EMC testing classification 1.
