Electrostatics - Part 5-2: Protection of electronic devices from electrostatic phenomena - User guide

This technical report has been developed to support IEC 61340-5-1. The controls and limits referenced in IEC 61340-5-1 were developed to protect devices that are susceptible to discharges of 100 V or greater using the human body model test method. However, the general concepts are still valid for devices that are susceptible to discharges of less than 100 V. The main changes with respect to the previous edition are listed below: This version has been modified to provide guidance for users of IEC 61340-5-1. The text has been arranged to follow the requirements of IEC 61340-5-1 as closely as possible as well as providing specific guidance on each of the requirements of IEC 61340-5-1. The contents of the corrigendum of May 2009 have been included in this copy.

Electrostatique - Partie 5-2: Protection des dispositifs électroniques contre les phénomènes électrostatiques - Guide d'utilisation

Le présent rapport technique a été élaboré comme lignes directrices à la CEI 61340-5-1. Les contrôles et les limites cités en référence dans la présente norme ont été établis pour protéger les dispositifs sensibles aux décharges de 100 V ou plus en utilisant la méthode d'essai du modèle du corps humain. Cependant, les concepts généraux restent valables pour les dispositifs sensibles aux décharges de moins de 100 V. Les modifications principales par rapport à l'édition précédente sont les suivantes: La présente version de la CEI 61340-5-2 a été modifiée afin de fournir des lignes directrices aux utilisateurs de la CEI 61340-5-1. Le texte a été disposé de manière à suivre les exigences de la CEI 61340-5-1 le plus fidèlement possible, ainsi que pour donner des lignes directrices spécifiques relatives à chacune des exigences de la CEI 61340-5-1. Le contenu du corrigendum de mai 2009 a été pris en considération dans cet exemplaire.
