Summary:
Many companies in Europe are using the floor/footwear system as a primary means for grounding personnel. The ECF are qualified according to the IEC 61340-4-1 based on their Rtg only. The conductive shoes are also qualified based on their Rtg only. We have found in many locations, qualified conductive epoxy floors,
used in conjunction with qualified ESD shoes, giving peak voltage values up to 600 volts and very long decay times. This paper reviews the situation in detail.
Introduction
More and more companies in Europe are using the floor/footwear system as a primary means for grounding personnel. Based on the new international standard, IEC 61340-4-1, the floor resistance to ground, Rtg, should be less than 1.106 ohm for an ECF. The shoe resistance through the wearer should be less than 35 Mohm.
