How shall the adaptive EPSs be verified for compliance with the regulation?

The European standard EN 50563 published in 2013 does not provide a testing methodology for adaptive EPSs that utilises the USB-C protocol. 

Annex II point 3 specifies that measurements and calculations shall be made using harmonised standards the reference number of which have been published for this purpose in the Official Journal of the European Union, or other reliable, accurate and reproducible methods, which take into account the generally recognised state of the art. Thus, a (future) harmonised European standard that would allow the measurement of adaptive EPSs, or any other generally recognised state-of-the-art testing methods could be used, provided that they are duly mentioned in the laboratory test reports. An example of such alternative method is the US DOE test method for adaptive EPSs. In this situation the applicable maximum power consumption for the no-load condition shall be 0,21 W.
