How to measure the static index of anti-static flooring?
In the field of electrostatic discharge protection, materials that are neither highly insulating nor highly conductive are advantageous. These materials are the so-called static dissipative materials, they are between the insulator and the conductor. Therefore, we can define them as materials with a surface resistance of 104~1011Ω and a volume resistance of 104~1011Ω·cm. The advantage of materials that are neither insulators nor conductors is that they can avoid static electricity accumulation or large currents.
Example measurement:
How to measure the static index of anti-static floor:
Anti-static floor is often used in anti-static production workshops. The surface resistance tester is often used to measure static index. Spread the anti-static floor flat. When measuring surface resistance, just place the instrument on the surface of the object to be measured and press The red test button, then the LED light will display the static index, and record the data by itself. In order to measure the anti-static floor more accurately, we will perform five measurements, namely the center and the corners of the anti-static floor. Ensure that the static index of every part of the anti-static floor is within the required range.
