Why You Need Julie Industries StaticSmart ESD Carpet
in the Networked Office Environment
1. What is ESD?
ESD is an acronym for ElectroStatic Discharge, commonly
referred to as static electricity, is generated when two materials contact and
separate. Repeated contact and separation, or friction, increases the accumulated
static charge. When contact is made between an object that is charged with static
and a conductive surface, electrostatic discharge, (ESD), occurs. One classic
example of an ESD event is a lightning bolt striking an object. Another example
of ESD is when you get a surprising shock as your hand touches a metal door handle.
ESD is particularly prevalent in environments when humidity is low. Some common
ways that static charges will accumulate on your body are:
- Rubbing a balloon on your head.
- Shoe soles walking on nylon carpet.
- Clothing moving on furniture fabrics or plastic surfaces.
- Clothing moving on human skin, (nylon stockings)
- Two clear plastic bags separating from each other.
2. What is the unit of static measurement?
The basic unit of measurement for static electricity is
the volt. The numbers are often so high that the kilovolt (Kv) is a commonly used
Typical Electrostatic Voltages at 20% Relative Humidity
- Sliding across a foam cushion
- Walking across a vinyl floor
- Walking across nylon carpet
- Walking across computer grade carpet
- Walking across StaticSmart ESD carpet
with ESD footwear
3. Is there a difference between human and computer
sensitivity to static?
Yes. Computers are much more sensitive to static electricity
than people are. Computer manufacturer's recommend that their equipment not be
exposed to voltage levels over 2.0 Kv, (see IBM user manual at www.IBM.com).
ESD related interference to computers is difficult to determine because people
are not aware that it is occurring. Human sensitivity generally begins at about
3.5 Kv. At this level an ESD event may cause you to feel a very slight tingling
on your body. The startling ZAPS!, that you feel when you discharge into a door
handle or metal object generally measure in excess of 5-8 KV. One thing is for
sure - If you can feel static, then you have a great potential for electronic
interference in your environment. Computer engineers estimate that static electricity
in the user's environment is the cause of up to 60% of all equipment service calls.

4. How does ESD cause computer downtime?
Most electronic equipment is programmed to function according
to specific electronic codes, a series of electrical pulses called binary code.
Unfortunately, the discharge of static electricity can also produce rogue electrical
pulses, or shock waves, which may influence the programmed electrical pulses in
the computer. This random and erratic ESD produces ElectroMagnetic Interference,
or EMI, which can cause false electronic signals, program interruptions, memory
loss and alteration of stored data. It is estimated that business losses in the
billions of dollars have resulted from daily systems interruptions caused by ESD
and EMI. To prevent your electronics from static interference and to keep static
generation at safe levels, you will need to design your facility with a built-in
permanent static control system.

5. What impact will new electronics technologies have
in your workplace
Currently, just about every commercial facility uses sensitive
electronic equipment. Whether it is desktop computers, network servers, data storage
devices, telecom switches and routers, wireless systems, communications equipment,
etc., these end-users are continually upgrading their electronics to keep pace
with their competitors in the Information Economy.In the future, as new electronics
technologies evolve, they will be even more advanced than they are today. New
microchip designs will be smaller, faster and run on less energy. They will be
more easily influenced by outside electronic interference. Optical storage technologies
based on laser light, like CD and DVD devices will be more susceptible to electronic
interference than the old floppy disks and magnetic disk drives we may have used.As
new electronic technologies are introduced, the facilities environments they are
used in must be designed protect them from any potential interference. One of
the significant changes we will see in the contemporary workplace will be how
the facilities and design departments will be required to work closely with the
IT and engineering departments. The integration of new building development trends
with emerging electronic technologies will present significant specification challenges
for both customer and vendor, as well. New "Smart Buildings" will be
designed to reduce and eliminate the threat of static interference to the electronics
they will surround.
6. Why is this change an important concern for the carpet
Now, more than ever, flooring specifiers need to consider
the static propensity (Kv rating), and the electrical resistance, (ER rating),
of commercial floor coverings. Static propensity measures how much static charge
a floor covering will generate. Electrical resistance measures the floor's ability
to safely dissipate a potentially harmful static charge. Understanding the difference
between static propensity and electrical resistance is a fundamental requirement
for flooring specifiers. New generations of electronics are being introduced that
require floors to have extremely low Kv ratings and ER ratings in the static dissipating
and conductive ranges.

7. Why is conventional anti-static protection in carpets
insufficient for today's workplace?
Conventional anti-static carpet is designed to enhance
human comfort only. Conversely, Julie Industries' StaticSmart ESD Carpet is designed
to enhance human comfort and improve the performance of electronic equipment.
Static electricity in the workplace is generated from many sources other than
the carpeted floor, such as clothing, the interaction of clothing and furniture,
plastic, etc. Anti-static carpet only ensures that the carpet itself does not
generate harmful static charges. StaticSmart ESD Carpet ensures that the carpet
and the people do not generate harmful static charges.
8. What is conductivity?
Ohms are a measure of electrical resistance. Electrical
Resistance measures the ability of a material to conduct an electrical charge
to ground. Ground is a point in an electrical circuit or building infrastructure
that has zero electrical potential. Ground provides a path to neutralize all electrical
A Conductor is a material with low electrical resistance
that will safely attract an electrical charge to ground. Examples of conductors
are water, copper, aluminum and carbon. A practical example of a conductor is
a lightning rod, or Julie Industries' StaticSmart ESD Carpet.
An Insulator is a material with high electrical
resistance that will not conduct a charge to safely ground. Examples of insulators
are plastic, rubber, vinyl, wood and most commercial and residential anti-static
carpets. A practical example of an insulator is the rubber or vinyl casings around
common electrical wires, or a commercial carpet tile with a low Kv rating.
Anti-Static refers to the ability to suppress charge
generation or the prevention of static build up. Anti-static materials will not
safely attract or decay a static charge before it randomly discharges. Anti-static
material is usually indicated by an electrical resistance range, measured in ohms,
of a minimum of 1.0 x 1010, (10 billion ohms), to a maximum of 1.0 x 1012, (1
Static Dissipative refers to the ability of a material
to conduct a charge to ground and is usually indicated by an electrical resistance
range, measured in ohms, of a minimum of 1.0 x 106, (1 million ohms), to a maximum
of 1.0 x 109, (1 billion ohms).
Note: Many ESD flooring
manufacturers will recommend electrical resistance measurements as high as 1.0
x 109, (1 billion ohms or "One Thousand Meg"). However, Julie Industries
feels that the gap between 100 million ohms to a 1 billion ohms is too large,
(900 million ohms), of a jump in electrical resistance. If the material's electrical
resistance happens to deteriorate over time, beginning at 1.0 x 109, it may not
provide adequate ESD protection over the useful life of the product.Conductive
refers to the ability of a material to conduct a charge to ground and is usually
indicated by an electrical resistance range measured in ohms of a minimum of 2.5
x 104, (25,000 ohms), to maximum of 1.0 x 106, (1 million ohms)
9. Why is conductive carpet better than anti-static
Obviously, the lower the electrical resistance, the more
conductive a material is. Naturally, since conductive materials measure lower
electrical resistance ratings, they will attract and decay static faster than
Static Dissipative materials. Likewise, Static Dissipative materials will attract
and decay static faster than Anti-Static or Insulation materials. Anti-Static
or Insulating materials will never attract or decay static charges. Most commercial
grade anti-static carpets are insulating range materials.
Julie Industries' StaticSmart ESD Carpet is conductive.
StaticSmart ESD Carpet has the ability to attract and remove harmful static charges
before they can be randomly discharged, keeping the total environment free from
costly static interference. It is specifically engineered to prevent the problem
of static interruptions in an electronics environment. StaticSmart ESD Carpet
contains an exclusive conductive carbon monofilament nylon, which inhibits the
generation of static on carpet while simultaneously conducting static charges
safely to a ground source. The patented engineering of Julie Industries' conductive
carpet system links these conductive fibers to a specially formulated conductive
pre-coat and a unique conductive vinyl backing. Applied with a full spread of
conductive adhesive and strategically positioned copper grounding strips, StaticSmart
ESD Carpet provides a safe route to ground for random ESD. This is an inimitably
advanced carpet technology that is simply not found in standard commercial and
residential anti-static carpets.
10. Does conductive carpet look different from other
No. Julie Industries' StaticSmart ESD Carpet is
available in many attractive styles. All StaticSmart ESD Carpet products maintain
the important features of contemporary color and design, appearance retention,
noise reduction, ease of maintenance and performance warrantees. Julie Industries
offers both running line and flexible custom design options.
11. When should Julie Industries' StaticSmart ESD Carpet
