ESD Statshield® Protective Smocks
Grounding, Testing and Maintenance
Description
Statshield Smocks are a Groundable Static Control
Garment System meeting the ANSI/ESD S20.20-2007
required limit of < 3.5 X 10E7 ohm RTG tested per ANSI/
ESD STM2.1.
“While a person may be grounded using a wrist strap or
other grounding methods, that does not mean that insulative
clothing fabrics can dissipate a charge to that person’s skin
and then to ground. Personnel clothing usually is electrically
separate or isolated from the body.” “Groundable Static
Control Garment System, Garments that are used to
establish the primary ground path for a person shall provide
a resistance of less than 35 megohms from the person to
the groundable point of the garment.”[ESD TR20.20-2008
section 5.3.13 Garments]
Outfitting a work force in ESD smocks is an important step
to demonstrate a company’s commitment to their ESD
control program. The Desco Statshield® ESD protective
smock is designed to be antistatic, low tribocharging, and
offers protection from electrostatic fields generated by
clothing on the user’s body. Using high quality material
with a minimum 9% carbon nylon monofilament, the smock
creates a Faraday Cage around the torso of the wearer.
Static charges generated by the wearer and wearer’s
clothing will be shielded from ESD susceptible products.
The dissipative material becomes part of the ground path
to remove static charges. The smock is available in two
lengths -- the lab coat length and the jacket length. Both
lengths are available in two styles - with snaps and with
conductive elastic cuffs. Smocks are available in six colors
-- blue, white, teal, burgundy, black, and camouflage.
COIL CORD TO GROUND
Made in America
The Desco Statshield® premium smock incorporates our
“hip-to-cuff” grounding feature which allows for hands-free
grounding with no tugging at the operator’s wrist. This
feature allows connection of a ground cord to a 4mm
snap stud on the hip. A seam of carbon-suffused threads
provides a secure and direct electrical connection from the
snap stud on the hip to conductive elastic cuffs, providing a
highly reliable connection via the user’s skin. The smock will
quickly and effectively ground the person when used in this
manner.
The smock is constructed of a lightweight dissipative
material which incorporates 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 the garment 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.
“After verifying that the garment has electrical conductivity
through all panels, the garment should be electrically
bonded to the grounding system of the wearer so as not to
act as a floating conductor.” [ESD TR20.20-2008 section
5.3.13 Garments] The conductive fabric in smock is a
conductor. If not grounded, the smock can become an
isolated charged conductor. If not grounded via a wrist strap
coil cord, ground the ESD garment using ESD footwear to
ESD flooring.
