Electrostatics - Part 4-6: Standard test methods for specific applications - Wrist straps

This part of IEC 61340 provides electrical and mechanical test methods and performance limits for evaluation, acceptance and periodic verification testing of wrist straps. NOTE All dimensions are nominal except where indicated. This standard is intended for testing wrist straps and wrist strap systems used for the grounding of personnel engaged in working with ESD sensitive assemblies and devices. It does not address constant monitoring systems.

Electrostatique - Partie 4-6 : Méthodes d'essai normalisées pour des applications spécifiques - Bracelets de conduction dissipative

L'IEC 61340-4-6:2025 donne les méthodes d'essai électriques et mécaniques et les limites de performance pour les essais d'évaluation, d'acceptation et de vérification de conformité des bracelets de conduction dissipative. Le présent document couvre les essais des bracelets de conduction dissipative et des systèmes de bracelets de conduction dissipative pour la mise à la terre du personnel amené à travailler avec des assemblages et dispositifs sensibles aux DES. Elle ne couvre pas les systèmes de surveillance continue. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) les commentaires rédactionnels formulés lors de la révision de la deuxième édition ont été revus et intégrés, le cas échéant; b) des références normatives ont été ajoutées pour couvrir la sécurité des appareils.
