Maintenance of Static Control
Systems 8200 Mats
Technical Brief – July, 1983
The basic purpose of conductive work surfaces is to
provide a surface that is free of static charge and also is
capable of removing the static charge from conductive
items placed on it. The total resistance to ground
determines the level of charge and rate at which it will be
drained. A resistance to ground of 1000 megohms or less is
required on an 8200 mat to drain a charge to a level of 100
volts or less in one second from a person or tote box
charged to 5KV (ref.1, 2).
Resistance Measurement:
Measuring the resistance of the mat requires a high voltage
megohmmeter. The megohmmeter must have a test voltage
of 50-100 volts and a meter range of 0-1000 megohms. The
ground lead of the megohmmeter is attached to the ground
points of the mat. The other lead of megohmmeter is
attached to an electrode that is described in both ASTM F
150 and NFPA 56A paragraph 4-6.2.7(b).

which bypasses the one megohm resistor in the ground

connection has been interrupted.
Cleaning:
Mats should be periodically cleaned with a detergent and
water solution. To reduce the possibility of leaving a
residue, detergents (rather than soaps) should be used.

detergent solution is needed to wipe off the mat; however,
hardened stains may require brushing with a semirigid
bristled brush. The wiping or brushing action should be in a
circular motion to ensure removal of the particles from the
surface depressions. Extremely soiled mats may require
several repeated cleanings with a water rinse between each

isopropanol and wipe the mat to remove any organic
contamination as well as the residual detergent. Avoid
using excessive isopropanol because the bottom foam layer
will absorb the solvent and cause the mat to swell.
previously described resistance measurement should be
performed to verify that the mat is functional.
