Description

Desco Heavy Duty Poly Cotton ESD Scrubs are made in
America and are designed to be low charging (antistatic),
and shield ESD sensitive items from electrostatic charges
generated by regular clothing.

Outfitting lab technicians in Desco ESD Scrubs is the single
most powerful step to demonstrate a company’s commitment
to their ESD / Static Control Program.

The Desco ESD Scrubs create a Faraday Cage effect
around the body of the wearer that shield ESD susceptible
items from static charges generated on the wearers’ clothing.

Our Static Control Garment’s fabric content is heavy duty
poly-cotton: 80% Polyester, 19% Cotton and 1% BASF
Carbon Suffused Mono-Filament Nylon.

Made in America

Instructions for use

Put on the garments and ensure no regular clothing is
exposed outside of the Top or Pants.

Note: EN 61340-5-1 paragraph 5.2.5 Garments “Coats,
jackets, smocks and overalls shall completely cover all
clothing in the area of the arms and torso.

“Garments that become worn or damaged should be repaired
or replaced by a qualified source to ensure the electrical
integrity of the seams. Once the repair is made, the periodic
test…should be conducted to validate the repair.” (ESD
TR20.20-2008 section 5.3.13.4.1 Repairs)

Fabric Specifications

Fabric Weight: 5 ounces/sq yard
Fabric Content: Texturized polyester (80%),

cotton (19%), 1% BASF carbon
suffused mono-filament nylon

Surface Resistance: RTG <1 x 10E9 ohms per ANSI/

ESD STM2.1

Static Decay Rate: 5,000 volts to 500 volts in less

than 0.1 seconds, per
FTMS-101C

Compliance Verification Testing

Panel to panel conductivity is essential and easy to test

using our Surface Resistance Tesk Kit Item #41290,

by placing 5 pound electrodes on different panels. For
additional information, refer to ANSI/ESD S20.20, ESD
TR20.20, the ESD Association Garment Standard,
ANSI/ESD STM2.1, and Compliance Verification ESD
TR53.

All of the seams in the garment are stitched with conductive
thread and designed to maintain electrical continuity from
panel to panel, sleeve to sleeve, leg to leg in accordance
with the ESD Association Garment Standard, ANSI/ESD
STM2.1.

Per the ESD Handbook ESD TR20.20-2008 section 5.3.13.1:
“Garments are intended to attenuate electrostatic fields that
may be present on personnel clothing.”

The Desco ESD Scrub has a Resistance point-to-point (Rtt)
<1 x10E9 ohms meeting the static control garment required
limit < 1 x 10E11 ohms of ANSI/ESD S20.20 when tested per
ANSI/ESD STM2.1 or ESD TR53.

Labeling

Label includes ESD protective symbol identifying the
garment as an ESD protective Garment. In addition
the label includes size, manufacturer traceability, fabric
composition, and laundering instructions. Label identifies
product as being made in America.

Maintenance

For proper operation, ESD garments 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. In terms of laundering
the smocks by hand or with a washing machine, most
prefer using a washing machine. This works well if using
a standard house machine on gentle cycle. Industrial
machines are fine 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.

The conductive fibers are 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 Heavy Duty Poly Cotton
ESD Scrubs will maintain their usefulness and
effectiveness for a minimum of 50 washings.

Unisex Sizing Chart

The unisex Desco ESD Scrubs are designed for both
men and women to wear these scrubs. The cut is a
loose fit. Thus women tend to size down. The sizing
chart is a guide to find the closet appropriate size.

Personnel Safety

Per ESD Handbook ESD TR20.20-2008 section

5.3.13.6 Other Considerations: “For personnel safety,
static control garments should not be worn in situations
where there is exposure to high voltage. Regular
laundering of static control garments according to the
manufacturer’s recommendation is suggested to make
sure conductive fibers do not become contaminated and
rendered insulative. After laundering, thorough rinsing
of the garment will help eliminate the possible buildup
of chemicals on the conductive fibers, which can cause
them to become insulative. Drying garments at high
temperatures may degrade conductive fibers in fabrics
used to manufacture garments.”
