Anyone interested in getting involved in their own country can find contact details here (if your country has not paid it dues to be a member of IEC TC 56 you cannot take part):,FSP_LANG_ID:1270,25

TC 56/WG2 is the working group responsible for IEC 60812,FSP_LANG_ID:2378,25

The documents on the IEC site are password protected. Here in the UK people can sign up to be members of an ISO committee for free (and thus gain password access). I suspect the same is also true of IEC committees here in the UK, but don't know for sure since I have not tried recently.
