The user and the smock will now be properly grounded. The
“hip to cuff” grounding feature allows greater freedom of
movement of user’s arms and hands, and a reliable path to
ground while the ESD smock offers extra protection against
damaging electrostatic fields which may be generated by
the user’s clothing.
NOTE: ANSI/ESD S20.20 REQUIRES THAT THE
GROUND CORD SELECTED FOR GROUNDING OF
PERSONNEL CONTAIN A BUILT-IN CURRENT LIMITING
1 MEGOHM RESISTOR.
Heat Sealed Patches
It is possible to heat seal patches to our smocks. The patch
should be small and the smock should be tested before and
after application.
Installation
Follow the directions below for proper installation and
grounding of the ESD smock.

Maintenance
For proper operation, the ESD protective smock must be
laundered periodically. Woolite works well. Liquid
detergents are better than dry in that there is less caking
and frictional wear. Launder garment in cool or warm water,
tumble dry with low heat or hang dry. Launder the smocks
by hand or with a washing machine. Use a standard
household machine on gentle cycle or use an industrial
machine if “Pony” (typically under 200 pound loads)
machines are used. It is not recommended to launder these
garments in heavy industrial laundry machines as it will lead
to premature wear. Garments should be tumbled dry using
low heat. DO NOT BLEACH.

Grounding Integrity Testing
For daily testing or monitoring of the grounding integrity of
Desco ESD protective smocks and ground cords, we
recommend the use of standard wrist strap testers or
singlewire workstation continuous monitors. Panel-to-panel
conductivity is essential so as not to leave portions of the
smock as isolated charged conductors. Panel-to-panel
conductivity is easy to test using our Surface Resistance
Test Kit Item #19780. Place the two five-pound electrodes
on different panels to test. Unless properly grounded, the
smocks can hold a charge and become a possible source
for discharge to ESD susceptible products. For additional
information, refer to ANSI/ESD S20.20, TR20.20, and the
ESD Association Garment Standard, ESD-STM2.1. Desco
has several testers available for this purpose. For
more information ask for specification drawings or operating
instruction manuals by item number.
