Electrostatics - Part 4-9: Standard test methods for specific applications - Garments - Resistive characterization
IEC 61340-4-9:2024 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 will not be able to measure materials with buried conductive layers.
This third edition includes the following significant technical changes with respect to the previous edition:
a) IEC 61010-1 and IEC 61010-2-030 added as requirements for measurement equipment;
b) testing voltage range for personnel ground path changed from "7 V DC to 30 V DC" to "7 V DC to 100 V DC";
c) cleaning requirements changed from a minimum of five cycles of cleaning to a minimum of three cycles of cleaning;
d) moderate humidity requirements deleted;
e) figures replaced with generic drawings.
Électrostatique - Partie 4-9: Méthodes d'essai normalisées pour des applications spécifiques - Vêtements - Caractéristiques résistives
L'IEC 61340-4-9:2024 fournit des méthodes d'essai pour mesurer la résistance électrique des vêtements utilisés pour des applications de contrôle des DES. Ces méthodes d'essai peuvent être utilisées pour évaluer des vêtements extérieurs conducteurs de façon homogène ou dissipatifs de façon homogène, ou qui comportent des composants ou des éléments à surface conductrice ou dissipative.
NOTE Il est possible que les méthodes d'essai spécifiées dans le présent document ne permettent pas le mesurage des matériaux à couches conductrices enfouies.
Cette troisième édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) l'IEC 61010-1 et l'IEC 61010-2-030 ont été ajoutées comme exigences pour les appareils de mesure;
b) la plage de tensions d'essai pour le chemin de mise à la terre du personnel est passée de "7 V à 30 V en courant continu" à "7 V à 100 V en courant continu";
c) les exigences de nettoyage sont passées de cinq cycles de nettoyage au minimum à trois cycles de nettoyage au minimum;
d) les exigences concernant l'humidité modérée ont été supprimées;
e) les figures ont été remplacées par des dessins génériques.

Part 4-9: Standard test methods for specific applications –
Garments – Resistive characterization
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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are caut
