Check the user's manual for the HF jack stands. It specifically says
"evenly distributed across two stands".

Of course, that doesn't prove that other manufacturers use the same system;
but I believe that in general, when they are sold as a pair, the rating is
for the pair.
IMO there is also a pretty big safety factor in the rating, at least for the
stands from HF. Although I don't propose to find out, I wouldn't be
surprised if my "6 ton" stands would support 12,000 pounds each under
optimum conditions.
