Figure 3. Grounding the smock
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.
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
single-wire 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/ Resistivity Tesk Kit Item #19770, by
placing 5 pound electrodes on different panels. 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 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.

Maintenance
For proper operation, the ESD protective smock must be
laundered periodically. Launder garment in cool or warm
water, tumble dry with low heat or hang dry. DO NOT
BLEACH. The carbon-suffused mono-filament nylon is
sensitive to heat and should not be exposed to laundering
heat in excess of 120°F. Use only non-ionic softeners and
detergents when laundering. Under normal wearing and
recommended washing conditions, Desco ESD protective
smocks will maintain their useful ness and effectiveness
for a minimum of 100 washings. Some other ESD smocks
have as little as 1% suffused carbon and lose their ESD
protective qualities after a few washings.
