You can get more information from the IEC web site. Go to 'web store 
search' and enter '61000-4-3'. that gets you a list of all versions, 
with the newest one at the top. You will see it has been amended twice 
and the latest version dates from April this year.

If you scroll down, you will se 'Stability date 2011'. This means that 
it won't be changed before 2011, and is actually inconsistent with the 
latest amendment being dated 2010, so I don't believe it.

A similar search for 61000-4-6 shows that the latest edition is dated 
2008-10, and no Stability Date is given.

There is another route to information. If, from the front page, you 
click on 'TC Dashboard', you get an input page that requires you to know 
the committee number. It is possible to get this from the Webstore 
search; just below the title of the publication. Just enter 77b, no 
TC/SC.

That leads you to a page with numerous choices. Click on 'Work 
programme' and you will see that there is no current work on 61000-4-3 
but a revised or amended 61000-4-6 is expected to be published in 2013.

You will see that the latest draft document is 77B/624/CD and if you 
click on that, you see details that include the closing date for 
National Committee comments, which was March this year. Since it has 75 
pages, it's a full revision, not an amendment.

You can't see the document, but if you go back to the 'choices' page and 
click on 'Working Documents', you get a long list that includes the 
result of the CD circulation, 77B/635/CC. Again, you can't see it, but I 
can tell you that there were very many comments, so it is likely that 
the 2013 date for a new edition is realistic.

>Are they going to be revised?  If yes, any idea what would be changed 
>(test frequency, instrument specification requirment, etc.?)

There is strong resistance to changing anything that introduces more 
testing or requires costly changes to test equipment, without very solid 
justification.

I hope the guide to the IEC web site is useful.
