It is described in MIL-STD-901. Depending on the mass of the equipment 
you are testing, there is a *light* hammer and a *heavy* hammer.
I have had some of my equipment tested to that level. The peak 
acceleration is in the 150-200G and the waveshape is very sharp, with 
lots of harmonics, to make sure ALL resonances are excited.
