I have all the documents at work, so I would not be able to post that section until Monday. I can't post the whole document, since that is not allowed.
In 61010-1 3rd Edition, the over voltage and surge tests have been removed. They are now covered in 61010-2-033 for DMM's and 61010-2-032 for clamp meters. Basically, a large surge event like 6kV or 8kV is a lightning type event, and would rarely happen. This is why the meter does not have to survive, but does still need to protect the user. The standard even states that you do not need any transient protection devices in the unit. However, "IF" you choose to install these protection devices, then they must be able to withstand 5 pulses in each polarity without being damaged. But, they are not required to be there, if the meter can take the surge without becoming a hazard.
A requirement that got tougher to meet in this latest standard is over voltage on any dial position. Past standards allowed you to state what level of protection you had designed in. For example, if you had a DMM that measured to 600V, you could say the the resistance input is only protected to 250V, and this was sufficient to pass the standard. Now, it states that the meter can not become a hazard if you have the full rated voltage on any switch position, and any jack combination. Again, the meter does not have to survive this, just not become a hazard. You can find a bunch of videos where the meter catches fire with 600V applied to the resistance input. That fails the IEC specs now. But, if it had failed gracefully, it would have passed. Of course, the better designed units can survive that over voltage, and still function.
