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.
