What do they do, send them to a certified and independent lab that runs 
the tests with calibrated equipment? That should only run a few thousand 
dollars so it must be something more than just intermod and harmonics 
they look at and probably over a very wide spectrum.

Back in the old days (BC) I did a wide range of instrument calibrations 
an took part in a couple of "round robin" groups in developing 
resistivity standards.  They had me doing everything from field strength 
measurements from 100KHz through about 10 MHz, to lifetime standards for 
single crystal Silicon.
