D. Surface-to-Groundable Point Test: Test samples per
Procedure: Place the Instrument on a table top or other
stable surface. Connect the test leads to the Instrument by
means of the right angle banana plugs. Connect the other
end of one of the leads to one of the test weights and place
the weight on the surface to be tested. Use one of the
supplied clips to connect the other lead to the groundable
point on the static control surface. Depress TEST button for
15 seconds and then record the reading.
E. Surface-to-surface Test: Test samples as shown in Figure
F. Repeat A through E after conditioning samples at 73°F
RESISTIVE CHARACTERIZATION
OF STATIC CONTROL FLOORING
GENERAL
This section provides a summary of installed or applied
floor material measurements specified and described by
ESD-S7.1.
NOTE: The following paragraphs are offered as a condensed
summary of the test methods and procedures outlined in the
EOS/ESD standard. For complete details, refer to the standard.
TEST DESCRIPTION
PERIODIC PERFORMANCE TESTING OF INSTALLED
OR APPLIED FLOORING MATERIALS(Measurement of
resistance from the surface of an installed floor to
GROUNDABLE POINT at ambient temperature and
humidity): Note: GROUNDABLE POINT is a point on the
floor material that is intended to accommodate an electrical
connection from the floor material to an appropriate
electrical ground. The ground point may be an electrical
ground, building ground, or other suitable ground. If you
have questions concerning the correct ground, refer to
EOS/ESD Standard 6.0 and/or contact a qualified
electrician.
The Resistance-to-Ground test is the most important test
that can be done on a static control surface because it
verifies that the surface is working correctly and will drain a
static charge in a reasonable time. This test involves
measurement of the total resistance from the static control
surface through the conductor or ground cord to the ESD to
the ESD GROUND (ESDG), verifying that the entire static
control system is functioning correctly.
NOTE: ESD 7.1 is designed to measure floor materials with
resistances of 2.5 x 10
The following procedures should be followed when testing
installed static control floor mats or flooring surfaces.
