IEC 61340-4-9:2024

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

Edition date: 2024-10-23
In Force
Available languages: English, French
Summary: 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.

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.

  • In addition, you can request the rules of the rest of the organizations through the e-mail normas@aenor.com
  • Technical books on paper and in electronic format (PDF, epub).

The standards can be purchased in PDF, reading or paper. The reading standards are not download files, they can only be viewed in the client area. The standards ordered on paper and some of the books in the catalogue are printed on demand. 

Check deadlines in normas@aenor.com.

The license of use is for one user and one device, if you want to reproduce the content of the standard, you must request a license that will have an additional cost. Send us your inquiry here 

The AENOR standards and books that appear in the online store can only be purchased exclusively through the website. AENOR does not have a physical store.

Purchase procedure: by clicking on "Buy" the desired products will go to the shopping cart. If there are display problems, the recommended browser is Chrome.

To formalize the purchase you must access the customer area. If you are not registered as a customer, you must fill in a form with the data along with a password and username. This will create the account.
