FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61340-4-9 has been prepared by IEC technical committee 101:
Electrostatics.
This second edition cancels and replaces the first edition published in 2010. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) classification of three types of garments
– static control garments,

b) additional measurements according to the the garment type including cuff measurements,
panel to groundable point, testing with a person in the garment system;
c) sleeve to sleeve measurements allowed with probes or by hanging;
d) additional recommended values for new garment types as set out in Annex A.
The text of this standard is based on the following documents:
FDIS Report on voting
101/500/FDIS 101/502/RVD

Full information on the voting for the approval of this standard can be found in the report on

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 standard 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 personal clothing can minimize the effect of this
charge. To effectively control electrostatic charges, the static control garment should be
grounded.
Three categories of garments are considered in this standard.
a) A static control garment may suppress or otherwise affect an electric field from clothing
worn underneath the garment without being attached to ground. However, without
grounding, a charge may accumulate on conductive or dissipative elements of a garment,
if present, resulting in a charged source.
b) A groundable static control garment may 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 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, 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 standard.
Garments constructed from fabrics made with fibres that are not surface conductive but may
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 standard.
This being the case, some garment fabrics and construction may allow for surface voltage
accumulation and charge transfer to occur which may be detrimental to electronic items.

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



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 The test methods defined in this standard may 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, 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.
