The current dates are as follow:
June 1, 2014, all Class 3 and Class 4.
Class 2 June 1, 2015
Class 1 June 1, 2016
However, there is a public consultation in-progress now.
The current proposal is as follow:
Class 4 January 1, 2015
Class 3 July 1, 2015
Class 2 January 1, 2016
Class 1 July 1, 2016
The public consultation end in February. As per MFDS officials feedback, it is very likely to be validated.
There is a link but I'm not allowed to post here.
I made an attachment which contain the links.
The new proposed dates can be found in the attachment of the first link - sorry all in Korean...
The previous dates are in the attachement of the second link of the word document.
and also sorry, all in Korean.
You made a valid point regarding the IEC 60601-1 Edition status globally. Some time ago I posted a file which is a working document. I attached it here. I requested the feedback of the covers here but didn't get any at that time.
I hope this helps.
