Charge Relaxation Time Test By Sigma

February 22, 2021

The Charge Relaxation Time compliments the Powder Volume Resistivity measurement as it indicates how long a material can retain its electrostatic charge. This is especially important with materials that are found to be insulating so as to minimise the risk from electrostatic spark discharges. Again the tests are performed at two relative humidity’s.

This test data is useful for operations that involve powder movement or storage such as pneumatic conveying, blending, milling, big bag storage etc.
