RRA Re-Announces the Application of Simplification of Test Items for USB or Battery-Powered Devices

-

 

Through the conformity assessment announcement in 2015, USB or battery-powered devices were permitted to simplify their conformity assessment tests. However, there have been instances of inappropriate use of simplified test items, prompting a re-announcement to clarify their application.


- When simplifying testing for USB or battery-powered devices, only Radiated Emission (RE) testing is applicable for EMI, and Disturbance Power (DP) testing cannot be used as a substitute.


- Disturbance Power (DP) testing is applicable when testing product groups that include conducted tests, and it is not applicable during simplified testing.
