Electrostatics - Part 4-9: Standard test methods for specific applications - Garments - Resistive characterization
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 might 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.

Overview
EN IEC 61340-4-9:2024 - published by CLC (CENELEC) - is the international/European test-method standard for the resistive characterization of garments used for electrostatic (ESD) control. It defines standardized laboratory procedures to measure electrical resistance of static-control garments and garment systems, including outer garments that are homogeneously conductive, homogeneously dissipative, or that use surface conductive/dissipative components. The standard clarifies which configurations can be measured (note: materials with buried conductive layers may not be measurable using these methods).
Keywords: EN IEC 61340-4-9:2024, electrostatics, garments, resistive characterization, static control garments, ESD garments, resistance test methods.
Key topics and technical requirements
- Scope of tests: Methods for measuring electrical resistance of garment panels, sleeves, cuffs and electrically interconnected components for ESD control.
- Principal test methods:
- Resistance point-to-point - resistance measured between two sleeves, two panels, or interconnected components (includes seams and cuffs).
- Alternate sleeve-to-sleeve - allowed variant using clamps to hang the garment.
- Resistance point-to-groundable point - for garments that include a designated groundable point.
- Groundable garment system (system test) - measures resistance from a person, through the garment, to the garment’s groundable point (includes the ground cord).
- Cuff/band measurements - references band resistance test in IEC 61340-4-6 for cuff designs intended to perform wrist-strap-like function.
- Equipment & conditions: Requirements for resistance measurement apparatus (including ohmmeters for personnel ground path testing), electrodes/clamps, insulative supports and specified atmosphere/conditioning for samples.
- Updates in 2024 edition: safety standards for measurement equipment (IEC 61010 series) added; personnel ground-path test voltage range expanded (previous 7–30 V DC → now 7–100 V DC); cleaning cycles reduced (minimum three); changes to humidity requirements and updated figures/drawings.
- Limitations: Methods may not detect buried conductive layers - users must be aware when selecting tests.
Applications and who uses it
- Quality and compliance testing for manufacturers of ESD/protective garments and cleanroom apparel.
- Independent test laboratories and certification bodies performing product qualification or acceptance testing.
- ESD program managers, procurement, and design engineers evaluating garment performance for sensitive electronic assembly, semiconductor fabs, cleanrooms and other static-sensitive environments.
- Health & safety and garment specification teams ensuring grounding performance for wearer-bonding garments.

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 can suppress or otherwise affect an electric field from clothing worn
underneath the garment without being attached to ground. However, without grounding, a
charge can accumulate on conductive or dissipative elements of a garment, if present,
resulting in a charged source.
b) A groundable static control garment 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 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. 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 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 can allow for
surface voltage accumulation and charge transfer to occur which can be detrimental to
electronic items.
Alternate methods for evaluating the electrostatic properties of garments are described in
IEC TS 61340-4-2 [1] .

Cela inclut également des vêtements qui incorporent des éléments conducteurs ou dissipatifs en surface, ce qui renforce la pertinence de la norme dans un contexte où la protection contre l'électricité statique est de plus en plus cruciale. L'un des points forts de cette norme est sa capacité à évaluer efficacement la résistance entre différentes parties d'un vêtement, par exemple entre les manches ou entre panels. La méthode d'essai point-à-point est particulièrement importante, car elle permet de mesurer la résistance à travers les coutures et les poignets, éléments souvent négligés dans d'autres méthodes de test. De plus, l'alternative de la méthode d'essai par manches – à l'aide de pinces pour suspendre un vêtement – montre la flexibilité de la norme dans l'application pratique. Un autre aspect remarquable est la prise en compte de la connexion électrique entre le porteur du vêtement et le sol, ce qui est essentiel pour garantir une protection efficace. La norme propose des méthodes spécifiques telles que le test de résistance point-à-point et le test de résistance vers un point à mettre à la terre, renforçant ainsi la sécurité des utilisateurs. Par ailleurs, le test de la bande de résistance, mentionné dans l'IEC 61340-4-6, pour les vêtements équipés de poignets similaires à des bracelets, montre également l'approche exhaustive adoptée par cette norme. En somme, la norme EN IEC 61340-4-9:2024 est d'une très grande pertinence dans le domaine de la caractérisation résistive des vêtements pour le contrôle électrostatique. Ses méthodes d'essai bien définies fournissent des outils fiables pour évaluer la sécurité et l'efficacité des vêtements, accroissant ainsi la confiance dans leur utilisation dans des environnements sensibles aux décharges électrostatiques.
