The IEC 61000-4-3 has been used for many years as the basic test standard for radiated electromagnetic field immunity testing in order to satisfy one of many European Union requirements for the CE mark.
This standard is usually used in conjunction with a product standard that will specify this and other test standards, detailing the requirements the product must meet. The product standard may give additional guidance on how this test standard is used, including test level severity and changes to procedure.
The object of this standard is to establish a common reference for immunity to radio frequency (RF) radiation caused by any source. Electronic products need to be designed and tested to have immunity from these sources. RF radiation can come from many sources such as other electronic devices, electric motors and intentional transmitters such as walkie-talkies and cell phones. The introduction of more wireless devices in the past couple of years has increased the need for this testing, not only to satisfy governmental requirements, but also to increase product reliability, which increases customer satisfaction.
