Why evaluate to Edition No. 2 of IEC 62368-1 now, when we will have to test to Edition No. 3 by 2020?
Evaluations to 3rdEdition will not universally be required in 2020. Edition No. 3 of IEC 62368-1 will not become mandatory until it is adopted in Europe, the U.S. and elsewhere and has an associated DOW in Europe and Effective Date in the U.S. If IEC 62368-1 Edition 3 is published in 2018, and national versions of Edition 3 are published in 2019 - in the EU (as EN 62368-1 Ed 3) and US (as UL 62368-1 Ed 3), these formal transition dates (DOW/Effective Date) likely will not be until approximately three (3) years from publication, or sometime in 2022.
