E.2 Electrostatic Charging of Persons
Charging
Every person with a non-conductive connection to the electrical potential of its
surroundings can be charged electrostatically.
Figure E-1 shows you the maximum values for electrostatic voltages which can
build up on a person coming into contact with the materials indicated in the figure.
These values are in conformity with the specifications of IEC 801-2.
