What I've seen is language like
"2011/65/EU RoHS directive with amendment 2015/863/EU"
or
"2011/65/EU RoHS directive as amended by 2015/863/EU"
The 2015 amendment adds four substances to the original six, so you should
mention both it and the 2011 directive.

I think it would be reasonable to expect that a product marked 100-240 Vac and
as compliant with 62368-1 would have been tested, where specified in the
standard to test to the "most unfavorable supply voltage," to values in the
90-264 range. If in doubt, you could ask the manufactu
for 230 Vac for the
EU market and want to sell it in Australia.

We have found "pre-screening" EMC testing early in the development cycle to be

when using EMC-savvy design principles. Extra PCB board spins are cheap in the
