Description:
Desco’s Statshield chair cover is a low charging, dissipative (1 x106 <1 x 109 ohms) material designed to
convert a standard chair into an ESD version. The Statshield chair cover is made from a polyester/cotton
blend fabric with BASF carbon suffused mono-filament nylon. The chair back and seat are connected
to a drag chain with a 1 megohm resistor that enables the chair cover to be grounded when used on a
conductive floor or mat. Desco’s Statshield chair covers are machine washable.
Specifications:
Grounding resistance:
1 megohm hermetically sealed resistor
Chain Length:

based on ANSl/ESD STM12.1, Seating - Resistive
Measurement
Static Decay Rate:
5000 volts to 500 volts in less than 0.01
seconds, per FTMS-101C

Seat:
18" x 20", maximum diameter 19" nominal
Back:
15 1/2" x 18 1/2", maximum diameter 17" nominal
Marking:
Product marked with ESD protective symbol to identify used
for ESD control
*Fabric lots vary slightly in color.
Laundering Instructions:
Use cool or warm water. Maximum temperature 120 °F. Do not use bleach, tumble dry on cool.
Installation Instructions:
Attach top part of cover to chair back and bottom part of cover (with grounding chain attached) to chair
seat. Make sure cover is fitted, centered, and secured to chair. Secure the ground chain to center post
underneath chair with hook and loop and make sure ground chain makes contact with ESD floor. A
minimum length of 6 inches of chain should make contact with the floor. For chairs with wheels make
sure the chain is clear of the wheels so that it does not become entangled with the wheels.

Technical Information from ESD Association:
“Fabric upholstered chairs accomplish this by using conductive
fibers woven into the fabric. The fabric is then connected through the
components of the chair, through the cylinder, base and casters (or
drag chain) to the floor.” [ESD Handbook ESD TR20.20 Seating section
