Medium Hammer
The 2.25 kg "Medium" Hammer was initially based on the
"standard proctor" 2.5 kg laboratory compaction hammer but evolved to its
present weight and drop-height for measuring shock attenuation characteristics of natural
and artificial playing surfaces. It is constructed to be the same size as the Standard
Hammer by using a mechanical combination of aluminum and hardened steel for the striking
end rather than steel with a hardened steel end as used for the Standard Hammer. In
the GTM style, shipping weight is a bit over 10 kg. Notation for the output is CIV/M when
the Medium Hammer is dropped from its standard height of 45 cm.
