Static electricity
Friction and ensuing separation of two objects can create tribo-electrification, the most common cause of static electrical discharge. This can cause electrical shocks when touching metal objects, foils and paper sticking together, static when removing clothes made of synthetic materials, and lightening. This discharge could cause damage to items like electrical equipment.
Electrical resistance
Floor coverings with low electrical resistance can rapidly dissipate electrical charges. Electrical resistance is expressed in Ohm (Ω)
Marmoleum ohmex is the dissipative linoleum floor covering.
Safety resistance
A floor’s electrical resistance can’t be too low. This could cause electrocution where there is contact with a mains voltage of 220-230 Volts.
According to the VDE0100/T160 a floor covering requires a minimal electrical resistance of: 5.104. This is called the safety resistance.
