“All personnel shall be grounded or equipotentially bonded according to the requirements
below when handling ESDS. When personnel are seated at ESD protective workstations,
they shall be connected to ground via a wrist strap system."
[EN 61340-5-1 Clause 5.3.3 Personnel grounding]
"A wrist strap system consists of three elements: the person, the wrist cord and a wrist
band. To ensure that the resistance to ground of personnel is within the specifications, it
is important to measure the entire system (i.e. from the person's body to the end of the
ground cord)."
“Wrist straps typically consist of a wrist band which makes contact with the wearer's
skin. The wrist band is then attached to a grounding cord which is connected to the ESD
ground reference.”
“The wrist band is a flexible, form-fitting device designed to make a reliable continuous
connection to a person's wrist."

“All personnel shall be grounded or equipotentially bonded according to the requirements
below when handling ESDS. When personnel are seated at ESD protective workstations,
they shall be connected to ground via a wrist strap system."
[EN 61340-5-1 Clause 5.3.3 Personnel grounding]
“The ground cord is a wire assembly that connects the wrist band to ground or to a common connection point. It usually consists of an insulated wire with a connector head that
attaches to the band on one end and a termination device on the other end for connecting
to ground. Ground cords usually contain a current-limiting resistor at the band-connecting
end. Any electrical connector that can be attached to ground is acceptable as long as it is
mechanically durable. The preferred grounding point for the groundable end of the cord is
a point connected to ground or to a common connection point.”
