INTRODUCTION
This part of IEC 61340 provides test methods for evaluating the electrical resistance of
garments that contain surface conductive or dissipative components or materials used in the
electronics industry for the control of electrostatic discharge. This document defines procedures
for measuring electrical resistance, including a system resistance test for garments that provide
a ground path for personnel.
Clothing made from synthetic fibres is a common source of electrostatic charge. Wearing an
appropriate static control garment over personnel clothing can minimize the effect of this
charge. To effectively control electrostatic charges of the static control garments and effectively
shield the electrostatic field of personnel clothing, the static control garment should be
grounded.
Three categories of garments are considered in this document.
a) A static control garment may can suppress or otherwise affect an electric field from clothing
worn underneath the garment without being attached to ground. However, without
grounding, a charge may can accumulate on conductive or dissipative elements of a
garment, if present, resulting in a charged source.
b) A groundable static control garment may can provide a higher level of suppression when
the lower resistance fabric is connected to ground.
c) A groundable static control garment system provides a ground path for a person that
suppresses the electrical field from clothing worn underneath the garment and also bonds
the skin of the wearer to an identified ground path. Groundable static control garment
systems may can also be used in conjunction with a continuous or constant monitoring
system in a manner similar to those used in continuous monitoring of wrist straps in an ESD
protected area (EPA).
Resistive characterization is only one aspect to consider in evaluating garments for any specific
application. To fully characterize a garment, it can be necessary to take into consideration
electrical field attenuation, static decay, peak voltage, residual voltage and triboelectric
charging may need to be considered. Other attributes related to applications and environments,
such as cleanroom compatibility, chemical and fire resistance, should be evaluated in the
garment selection process but are beyond the scope of this document.
Garments constructed from fabrics made with fibres that are not surface conductive but may
can have other related properties that impart some level of electrostatic charge dissipation or
suppression when connected to ground, are not specifically measured by the methods provided
in this document. This being the case, some garment fabrics and construction may can allow
for surface voltage accumulation and charge transfer to occur which may can be detrimental to
electronic items.
Alternate methods for evaluating the electrostatic properties of garments are described in
IEC TS 61340-4-2 [1] .

ELECTROSTATICS –
Part 4-9: Standard test methods for specific applications –
Garments – Resistive characterization

1 Scope
This part of IEC 61340 provides test methods for measuring the electrical resistance of
garments used for static control applications. These test methods can be used for evaluating
outer garments that are homogenously conductive or homogeneously dissipative, or that utilize
surface conductive or surface dissipative components or elements.
NOTE It is possible that the test methods defined in this document may will not be able to measure materials with
buried conductive layers.
The resistance point-to-point test method tests the electrical resistance between the two
sleeves, any two panels or any two or more electrically interconnected components of the static
control garment, including the electrical resistance across the seams and cuffs of the garment
as applicable.
An alternate sleeve-to-sleeve test method is allowed described, using clamps to hang a
garment.
Static control garments that electrically bond to the wearer and provide a path to ground from
the wearer are evaluated using the resistance point-to-point test method, the resistance point-
to-groundable point test method, as well as a system test to determine the resistance from the
person through the garment to the groundable point of the garment system.
A band resistance measurement test is provided in IEC 61340-4-6 which can be used for
garments so equipped with cuffs that are intended to perform the same function as a wrist strap
band.
The system test with a person wearing a groundable static control garment system includes the
ground cord that connects to the groundable point of the garment.

5.3 Support surface
5.3.1 Insulative support surface
An insulative surface when used for specimen support shall have a surface resistance of greater
than 1,0 × 10 Ω when measured in accordance with IEC 61340-2-3. The insulative surface
shall be large enough to accommodate the entire garment when it is laid out flat.
5.3.2 Insulative sleeve inserts
Two pieces of insulative material meeting the requirements of 5.3.1 cut into approximately
75 mm by 152 mm strips to slide into the sleeves (and cuffs if so equipped) of garments under
test to isolate one side of the sleeve from the other.
5.3.3 Insulative hangers
The points to which the clamps described in 5.2.2 holding a garment under test shall be isolated
from ground by a resistance greater than 1,0 × 10 Ω when measured with an instrument
meeting the requirements of 5.1.3. Insulating thread may can be used for this purpose.

6 Test procedure
6.1 Sample preparation
6.1.1 General
The test samples shall be processed through a minimum of five cycles of the garment
manufacturer’s prescribed or user defined cleaning process prior to performing laboratory tests.
6.1.2 Sample size
Test a minimum of three samples for each style and manufacturer for product qualification. For
acceptance testing, the sample size shall be determined by the user.
6.1.3 Sample sketch
Garments can have a temporary finish on them, either a residue from processing treatments or
deliberately applied by garment manufacturers, that can reduce electrical resistance. Such
finishes shall be removed before proper evaluation of the long-term properties of garments can
be made. This can be achieved by processing garments through a minimum of three cycles of
the garment manufacturer's specified or user defined cleaning process, prior to performing
laboratory tests. 3
The person performing the tests should examine the garment's construction and make a general
sketch showing separate front and back panels used to fabricate the garment. Number the
panels for measurement identification purposes from No. 1 to No. n. Identify the sleeves and
cuffs as left and right. The groundable points, if they exist, should be shown on the sketch. The
sketch should accompany the test results to become part of the test report.
6.1.2 Number of samples
Test a minimum of three samples for each style and manufacturer when using this test method
for qualification.
6.2 Humidity requirements
For product qualification, resistance point-to-point, resistance point-to-groundable point and
cuff measurements shall be conducted at two humidity conditions according to Clause 4.
Humidity conditioning for product qualification of the groundable static control garment system
is optional and may can require a walk-in environmental chamber.
NOTE Laboratory testing has shown that low and moderate humidity conditions do not have a consequential impact
on the electrical resistance measurement of a garment in combination with a person.
6.3 Test procedures
6.3.1 General
Subclause 6.3 defines the test methods for measuring the electrical resistance of garments. It
includes a resistance point-to-point test and a resistance point-to-groundable point test. The
described test procedures may can be used for product qualification and acceptance testing. A
system test for a garment that provides a path to ground from a person while being worn is also
described.
6.3.2 Resistance point-to-point
6.3.2.1 Panel-to-panel
Precondition the test samples according to 6.2 as required. Place the garment on an insulative
support surface as described in 5.3.1. Place the garment with the front panels opened and laid
out as flat as possible (it is possible that larger garments such as overalls may will not allow

– 12 – IEC 61340-4-9:2024 CMV © IEC 2024
this completely). Place the insulative sleeve inserts from 5.3.2 into each sleeve (including the
cuff, if so equipped, or leg cuffs of an overall) of the garment under test. Attach test leads from
the resistance measuring apparatus (meter) to the electrodes defined in 5.2.1. Place one
electrode on a panel of the sample. Place the second electrode on another panel of the same
sample. Ensure the panels are on the insulative support surface and do not touch any other
part of the garment. Apply 10 V and observe the reading after 15 5 s. If the reading is less than
6 6
1,0 × 10 Ω, record the value. If the reading is greater than or equal to 1,0 × 10 Ω, apply 100 V
for a minimum of 15 s (or until reading stabilizes) and record the results. Switching the test
voltage to 100 V can result in a resistance reading of less than 1,0 × 10 Ω. When this occurs
the reading made with the 100 V test voltage shall be recorded. Repeat for all electrically
interconnected components and panels as well as exterior cuff-to-cuff and sleeve-to-sleeve,
making sure that the electrodes are directly above the insulative inserts (see Figure 1, Figure 2
and Figure 3). Resistance point-to-point measurements can give variable results depending on
the arrangement of the garment under test and location of electrodes on it. For qualification
testing, at least three measurements shall be made with the garment arrangement and electrode
location re-arranged between each measurement. The result is the highest of the three
measured values 4. Repeat for all test samples.
6.3.2.2 Interior cuff-to-cuff
Some garments may can have an insulative exterior and conductive interior of the cuff or
incorporate a wrist strap band or another wrist bonding mechanism or device. Precondition the
test samples according to 6.2 as required. Insert the measurement electrodes inside the cuffs
or wrist bonding devices (see Figure 4 and Figure 5). Apply 10 V and observe the reading after
15 5 s. If the reading is less than 1,0 × 10 Ω, record the value. If the reading is greater than or
equal to 1,0 × 10 Ω, apply 100 V for a minimum of 15 s (or until reading stabilizes) and record
the results. Switching the test voltage to 100 V can result in a resistance reading of less than
1,0 × 10 Ω. When this occurs, the reading made with the 100 V test voltage shall be recorded.
Repeat for all test samples.
6.3.2.3 Hanging clamp sleeve-to-sleeve
Precondition the test samples according to 6.2 as required. Hang the garment from each sleeve
with electrically isolated clamps (see Figure 6). Place the clamps so that they connect the
exterior and the interior of the cuff. The resistance measurement shall be made by applying
the voltage lead (positive) to one clamp and attaching the sensor lead (negative) attaching a
test lead to one clamp and attaching the other test lead to the other clamp. Apply 10 V and
observe the reading after 15 5 s. If the reading is less than 1,0 × 10 Ω, record the value. If the
reading is greater than or equal to 1,0 × 10 Ω, apply 100 V for a minimum of 15 s (or until
reading stabilizes) and record the results. Switching the test voltage to 100 V can result in a
resistance reading of less than 1,0 × 10 Ω. When this occurs, the reading made with the 100 V
test voltage shall be recorded. Repeat for all test samples.
6.3.3 Resistance point-to-groundable point
Precondition the test samples according to 6.2 as required. Place the garment with the front
panels opened and laid out as flat as possible (it is possible that larger garments such as
overalls may will not allow this completely) on an insulative support surface as described
in 5.3.1. Use one electrode as described in 5.2.1 connected to the positive one test lead of the
meter. Place the insulative sleeve insert from 5.3.2 into each sleeve of the garment under test.
Place the electrode on a cuff (or inside as described in 6.3.2.2 see 6.3.2.2 for interior cuff-to-
cuff measurements), sleeve (directly above the insulative insert) or panel. Connect the negative
other test lead of the meter to the garment groundable point. Apply 10 V and observe the
reading after 15 5 s. If the reading is less than 1,0 × 10 Ω, record the value. If the reading is
greater than or equal to 1,0 × 10 Ω, apply 100 V for a minimum of 15 s (or until reading
stabilizes) and record the results. Switching the test voltage to 100 V can result in a resistance
reading of less than 1,0 × 10 Ω. When this occurs, the reading made with the 100 V test voltage
shall be recorded. If cuffs are designated as groundable points, measurements shall be made
between sleeves and cuffs or between panels and cuffs; see 6.3.2.2 for cuff-to-cuff

measurements. Repeat for all panels, sleeves and cuffs and groundable points (see Figure 8
and Figure 9). Repeat for all test samples.
6.3.4 Cuff measurements
IEC 61340-4-6 provides test methods for the evaluation of wrist strap bands and cuffs. These
methods may can be adapted for use in testing garment cuffs or any wrist strap cuff type
grounding mechanism that may can be part of a garment and used to bond to the skin of the
wearer. The band resistance test procedure described in IEC 61340-4-6 may shall be used to
measure the interior resistance of the garment cuff or wrist strap grounding mechanism (see
Figure 10).
NOTE Some garments can be used in conjunction with resistance continuous monitoring systems. Garments of this
type can have one cuff that provides the skin contact for personnel grounding, and the other cuff is used for monitoring
the electrical continuity between the garment and the wearer. The two cuffs are isolated electrically from each other
in this type of garment. The manufacturer can be contacted for assistance in measuring this type of garment.
6.3.5 Groundable static control garment system
Users of this document should ensure that garments tested in this procedure meet the
grounding requirements at the lowest humidity levels experienced in their facility.
This procedure verifies the resistance path from a person wearing the garment, through the
body-garment cuff contacts or wrist strap cuff type grounding mechanism to the ground
termination point of the garment grounding wire. Testing in a controlled environment is not a
requirement of this subclause. Personnel shall wear the garment under test for a minimum of
10 min prior to testing.
This test is conducted with the meter described in 5.1.4. This test includes the ground cord and
wearer's resistance as part of the total system resistance (see Figure 11 and Figure 12). The
test can be performed using a proprietary integrated tester (Figure 12) or resistance meter of
similar specification (Figure 11). Connect the grounding point of the garment to the tester using
the ground cord. Contact is made to the tester via a push button, contact plate (on the integrated
tester, Figure 12) or a hand-held electrode (Figure 11). Apply the test voltage and record the
result.
