Surface resistance/resistivity

With circular electrode or polymeric blade electrode (Bayer electrode). Documentation in report as direct result (depending on electrode) and surface resistivity. Conditioning as agreed, measurements even under conditions deviating from the standard climate of 23°C/50% r. h. possible in climate chamber.

This test determines the electrical surface resistance of flexible packaging materials to assess their electrostatic properties. Using specialized circular or blade electrodes, a defined voltage is applied to the material surface to measure how effectively it conducts or dissipates electrical charges.

The resulting values indicate whether a material is antistatic, dissipative, or insulating. This information is essential for packaging developers to prevent hazardous static discharges in sensitive environments, such as those involving flammable substances or electronic components.
