With the development of electrical and electronic technology, household appliances are becoming increasingly popular and electronic, radio and television, post and telecommunications and computer networks are becoming increasingly developed, and the electromagnetic environment is becoming increasingly complex and deteriorating, making the electromagnetic compatibility of electrical and electronic products (EMC electromagnetic interference EMI and electromagnetic anti-EMS) issue is also paid more and more attention by governments and manufacturers. The European Community government stipulates that from January 1, 1996, all electrical and electronic products must be certified by EMC and affixed with the CE certification mark before they can be sold in the European Community market. This has caused a wide impact in the world, and governments have taken measures to implement mandatory management of RMC performance of electrical and electronic products. According to the EU's Electromagnetic Compatibility (EMC) Directive 2014/30/EC, all electronic and electrical products sold in the EU market must strictly comply with EU legal requirements in terms of their interference with other products and their resistance to external influences. -- -- -- < a href = "http://www.globalgd.com/" > < strong > CE certification body < / strong > < / a > < / div >
