SELECT ESD FLOOR
COATINGS FOR STATIC CONTROL
Overview and goals: The
purpose of the following testing is to identify floor coatings
that fully comply the latest recommendations of ANSI ESD S
2020-2007 (the latest standards) with an electrical resistance
level (per 97.1 testing) of < 3.5E07 (35 meg-ohms). 97.1 is a
combination resistance test that takes into account the
technician, in conductive heel straps in conjunction with the
resistance values of the flooring material and it's attachment
to ground.
Recent industry accepted
standards have changed dramatically in the last two years to
better accommodate the increased sensitivity of today's advanced
micro circuitry to an electrostatic discharge event. A flooring
material that is merely below 1.0E09 no longer meets the new
standards in most instances. ESD flooring that falls in the static dissipative
range will soon become obsolete.
Chemical coatings that
increase the conductivity of existing anti-static (static
dissipative) flooring will
provide a viable, cost effective alternative to total esd
flooring replacement or for use as an economical covering for
existing vinyl composition tile (VCT) and bare concrete. Thus it
is the goal of this study to provide documented evidence of coating conductivity and to identify materials that meet the
new resistance levels.
Introduction: This report documents a series of electrical
conductivity test performed on various substrates including concrete filled metal testing
trays rendered esd (static control) compliant via the
application of
ElectraGlaze ESD Floor Wax,
ElectraGuard ESD epoxy Paint and
ElectraSeal static
control concrete sealer.
Grounding of
substrate specimen comprised of an appropriately placed Copper
3' x 3' x .125 thick panel reliably attached to primary
electrical building ground and placed beneath the concrete
filled galvanizedsubstrate testing tray. All materials tested were
manufactured in compliance with specifications issued by United SCP Incorporated to (and by) United SCP approved chemical manufacturers.
The following testing was performed in a temperature and
humidity controlled environment set to replicate many typical
job site environments. All testing was performed in
accordance with the Industry Accepted Standards of EOS-ESD S7.1
as specified by ANSI ESD S 20.20-2007.
Equipment: Equipment interpreting readings of
electrical conductivity consisted of a Prostat PRS-801 (S.N. #
4990149) precision resistance instrument operated by a
programmed microprocessor (controlling voltage selection,
electrification periods and display functions). It should be
noted that each reading posted by the Prostat actually
consist of over 100 multiple resistivity readings of
which the device collects, averages and stores. Collected
representative readings from testing procedures were
subsequently stored in non-volatile memory storage device and
transferred electronically to Notebook Computer. Accuracy of
readings at this range (with selected cables and electrodes
utilized for this test) is +/- 2%. Original calibration and
certification of testing system was performed by said
manufacturer on 11/12/09 and is valid for one year from this
date. All calibration for testing instruments were provided in
accordance with NCSL Z540, traceable through reference standards
maintained by the National Institute of Standards and Technology
(NIST), by comparison to natural physical constants or
self-calibrating ratio type measurements.
Data from procedures were collected; results averaged, condensed
and documented as follows.
