Compliance testing for electronic devices include emissions tests, immunity tests, and safety tests.<ref name="ECMAAGuide99">{{cite web |url=https://www.ecma-international.org/publications/files/ECMA-TR/ECMA%20TR-074.PDF |title=ECMA Technical Report TR/74: A Guide to the Application of the EMC Directive to ITE |publisher=ECMA |date=June 1999 |access-date=22 February 2018}}</ref> Emissions tests ensure that a product will not emit harmful electromagnetic interference in communication and power lines. Immunity tests ensure that a product is immune to common electrical signals and [[electromagnetic interference]] (EMI) that will be found in its operating environment, such as [[electromagnetic radiation]] from a local radio station or interference from nearby products. Safety tests ensure that a product will not create a safety risk from situations such as a failed or shorted power supply, blocked cooling vent, and powerline [[voltage spike]]s and dips.

For example, [[Ericsson]]'s telecommunications research and development subsidiary [[Telcordia Technologies]] publishes conformance standards for telecommunication equipment to pass the following tests:<ref name="EricssonElectro17">{{cite web |url=http://telecom-info.telcordianjdepot.comericsson.net/site-cgi/ido/docs.cgi?ID=SEARCH&DOCUMENT=GR-1089& |title=Electromagnetic Compatibility and Electrical Safety - Generic Criteria for Network Telecommunications Equipment |publisher=Ericsson |date=December 2017 |access-date=22 February 2018}}</ref>

; Radiated immunity : An [[antenna (electronics)|antenna]] is used to subject the device to [[electromagnetic waves]], covering a large frequency range (usually from 80&nbsp;MHz to 6&nbsp;GHz).
