Regulation EN1149-3 Antistatic

The sample is placed between two electrodes and it is charged by induction. In this method, a fabric sample is electrically charged. If it has electrostatic properties, the sample will get chargings with the opposite induction sign.

This value shall be higher than 0,20. The second value obtained is the semi dissipation time of the charging (t50). It measures the time that the fabric takes to dissipate all the accumulated electricity and it shall be lower than 4 seconds.
