IEC 61920-ed.2.0

Annotation of standard text IEC 61920-ed.2.0 :

IEC 61920:2004 describes the classification of IR devices into groups and classes in order to identify and clarify problems caused by mutual interference. Mutual interference is caused by the increasing parallel application of different infrared (IR) systems. The wavelength range from 700 nm to 1 600 nm is considered. All systems based on free air application which intentionally or unintentionally use IR radiation in this range, are included. This second edition cancels and replaces the first edition published in 1998 and constitutes a technical revision. This bilingual version (2012-08) corresponds to the monolingual English version, published in 2004-01. La CEI 61920:2004 decrit la classification de dispositifs infrarouge en groupes et classes pour identifier et clarifier les difficultes provenant des interferences mutuelles. Ces interferences sont provoquees par le nombre croissant dapplications comportant differents systemes infrarouges en parallele. Les longueurs donde comprises entre 700 nm et 1 600 nm sont prises en consideration. Tous les systemes a base dapplications dinfrarouges non guides utilisant intentionnellement ou involontairement des rayonnements infrarouges dans cette gamme sont inclus. Cette deuxieme edition annule et remplace la premiere edition parue en 1998, dont elle constitue une revision technique. La presente version bilingue (2012-08) correspond a la version anglaise monolingue publiee en 2004-01.
