What is EMC Testing?

Writer： admin Time：2019-10-11 13:57 Browse：℃

　　EMC is an acronym for Electro Magnetic Compatibility. All electronic devices have the potential to emit and be susceptible to electromagnetic fields. With the proliferation of electronic devices into everyday life there is a huge potential for devices to interfere with each other. No electrical product or installation’s design can be considered complete unless all aspects of EMC are taken into account.
 

　　This is not only important for common products such as television sets, computers, washing machines, etc.; it is especially important for complex products such as vehicles, aircraft, ships and large industrial installations. These are very sensitive to EMC problems. Compatibility testing allows you to observe the interaction of all electrical and electronic equipment operating in the same environment.
 

　　EMC Testing is a long term investment since it provides evidence that your product complies with relevant EMC regulations and directive(s). After a successful test program, you can be confident that your product’s reliability will be increased, thus reducing warranty issues and servicing costs, and encouraging brand loyalty. Testing also highlights potential issues or problems with the product that can be fixed before production. Having the right EMC test equipment and design provided by a reliable strategic partner can play a key role in the long term success of your product.
