EMC Product standards may apply either to particular products, such as electricity meters and printed circuit boards, or to a group of products that have common general characteristics, that may operate in the same environment and have neighbouring fields of application. Medical devices, IT equipment (ITE) and low-voltage household equipment are examples of such groups.
In the latter case, the publication is known as an EMC Product Family standard. If the field of application is particularly wide, covering the scopes of several IEC product committees, it will be developed by one of the 'horizontal' committees. The IEC Advisory Committee on Electromagnetic Compatibility (ACEC) maintains a list of all the main product families covered by IEC EMC standards.
