The number in the circle is an indication for the "Environment Friendly Use Period", the period in which it's safe the contained substances will not leak out. 10 in your circle means that it's pretty safe that for 10 years, no RoHS-critical substances will leak out.

Which Standard does include it?
I had a look into EN 62368-1 and couple of other Standards and regulations.
Could not find any source showing this logo.
Is it voluntary or is it a mandatory by and Standard or Regulation?
Does anyone know?

I am searching for the meaning of some other symbols present on power supplies.
And I already found information on many symbols on the web, for example:

http://www.technick.net/public/code/cp_dpage.php?aiocp_dp=guide_safetymarks
http://www.swecheck.com.au/pages/learn_product_approvals.php
http://www.atbatt.com/laptop-chargers.asp

http://www.energystar.gov/ia/partners/prod_development/revisions/downloads/International_Efficiency_Marking_Protocol.pdf

However I cannot find the meaning of the symbol "10" surrounded by 2 arrows, like on the right side of picture here:

Do you know the meaning of this "10" symbol ?
