The 4.5 kg "Standard" Clegg Impact Soil Tester was the first Clegg Hammer developed by Dr. Baden Clegg in the 1970's. It was initally conceived for racecourse testing but has turned out to be the "general purpose" Clegg. It is based on the instrumentation of a "modified proctor" laboratory compaction hammer.

The Hammer mass is 5 cm in diameter at 4.5 kg and is dropped from a set height of 45 cm. In the GTM style, the weight of the guide tube and metre is approximatley 1.6 kg. The shipping case weighs 6 kg. Total weight is 12 kg. Instrument height is 70 cm and the guide tube is 15 cm in diameter. The shipping case is around 25 cm by 25 cm by 80 cm. The output of the standard Hammer when dropped from its standard height is known as the Clegg Impact Value (CIV).
