Static discharge behaviour

There are three basic routes to modify the static discharge behaviour of plastics used in building or other applications ... 

The surface resistivity is easy and relatively reproducible to determine with the ring electrode but it is limited for various reasons, for example it is based on a static test with no information about the important charging and discharging behaviour of the textiles. Therefore, combination with a charge dissipation test is favoured. 

A material s behaviour in the proximity of electrical fields or discharges and the static build-up and dicharge behaviour of a material are tested. Tests include volume and surface resistivity, permittivity, breakdown strength, insulation resistance, power (or loss) factor and tracking resistance.
