IEC 705-88 Microwave Oven power measurement???what is it?

What is the IEC 705-88 procedure for measuring microwave
oven power output?

I've googled myself silly. Only thing I found is one
Amazon book excerpt. Starts describing the procedure,
but deletes two pages out of the middle...please insert
$200 to read the entire article...thankyouverymuch.

Maybe if I write it 5 times, the message will get through.

I know how to measure it with a thermometer and a stopwatch.

What I'm asking is...
When I go to the store and look at the numbers written
on the box that state the power output per iec705,
what do THEY mean...and how does that relate to what I'm
gonna find when I use my stopwatch and thermometer.

One more time.

I'm asking how IEC705 measures power output.
