New instrument for powder testing

The new EVOLUTION Powder Tester measures a powder or granular material’s response to environmental stresses. The major stress on a material is pressure.

The EPT measures a material’s response to pressure by applying pressure to the material and then measuring its resulting strength. This strength is known as the unconfined yield strength. If a powder is to flow, the force making the powder move must be greater than the unconfined yield strength.
