Installation
Description
Follow the directions below for proper installation and
grounding of the Statshield® smock.
Desco Statshield® Smocks with Convertible Sleeves
are designed to be antistatic, low tribocharging,
and create a Faraday Cage around the torso and
arms of the wearer to protect ESD susceptible items
from electrostatic fields generated by clothing on
the operator’s clothing. Static control garments are
intended to attenuate electrostatic fields that may be
present on personnel clothing. Statshield® Smocks
meet the requirement for Groundable Static Control
Garment System per ANSI/ESD S20.20 required
limit of < 3.5 x 107 ohm Rtg tested per ANSI/ESD
STM2.1 and ESD TR53 (23° ± 1° C, 12% ± 3% RH,
and 50% ± 5% RH).
Yes
Statshield® smocks are constructed of a lightweight
dissipative material which made from texturized
polyester and a minimum of 9% carbon nylon
monofilament. The conductive nylon fibers are
woven in a chain-link design throughout the
material, providing continuous and consistent
charge dissipation. All of the seams in Statshield®
smocks are designed to maintain electrical continuity
from panel to panel and from sleeve to sleeve in
accordance with the ESD Association Garment
Standard, ESD-STM2.1.
Standard Colors Available:

Figure 2. Proper Installation of Smock wearer’s body
1. Put on the smock and fasten all of the snaps on the
front of the smock, making sure that clothing is not
exposed outside of the smock.
2. Operators may roll up sleeves, so long as all clothing
remains covered. Operators wearing long sleeved
shirts must leave the sleeves down. Operators must
be grounded with foot grounders or wrist straps when
wearing a smock and handling any ESD susceptible
items.
3. Throughout use, it is essential that material be in
contact with operator’s skin.

Grounding Integrity Testing
Panel-to-panel conductivity is essential so as not
to leave portions of the smock as isolated charged
conductors. Panel-to-panel conductivity is can be
tested using the Surface Resistance Meter Kit. For
additional information, refer to ANSI/ESD S20.20,
ESD TR20.20, ESD TR53 and the Garment Standard,
ANSI/ESD STM2.1.

Heat Sealed Patches
Patches may be heat-sealed to the smocks. The
patch should be small and the smock should be
tested before and after application.
Maintenance
Desco recommends Woolite. Liquid detergents are
better than dry because there is less caking and
frictional wear. Use only non-ionic softeners and
detergents when laundering. Launder Statshield®
smocks in cool or warm water, tumble dry with
low heat or hang dry. DO NOT USE BLEACH OR
FABRIC SOFTENER.
*Fabric lots vary slightly in color and weight.
Limited Warranty, Warranty Exclusions, Limit of
Liability and RMA Request Instructions
See Desco Terms and Conditions
Use a standard household machine on gentle cycle or
industrial machine “Pony” (typically under 200 pound
loads) machine. It is not recommended to launder
these Statshield® smocks in heavy industrial laundry
machines because it will lead to premature wear;
degrading the ESD properties.
Statshield® smocks should be tumbled dry using
low heat. The carbon-suffused mono-filament nylon
is sensitive to heat and should not be exposed to
laundering heat in excess of 120°F. Under normal
wearing and recommended maintenance conditions,
Desco Statshield® ESD protective smocks will
maintain their usefulness and effectiveness for a
minimum of 100 washings.
