Centrifuge system for testing waterproof footwear launched
05/01/2007
Indiana-based centrifuge manufacturer U.S. Centrifuge has developed a way of testing military boots to ensure soldiers’ feet stay dry in harsh conditions. The system uses a centrifuge to spin the boots around, filled with water, to prove liquid is unable to leak out or seep in.
Spinning the boots in a centrifuge forces the water to find any route through or around the waterproof material.
The machine can test up to 16 boots at a time, each containing 400cc of water, spinning them around at just 170rpm to create a water pressure of 2psi at the sole. Each test cycle takes 30 minutes.
It is expected that the project will be extended to test other shoes and boots, including golf shoes.
