IEC 61097-14:2010

Global maritime distress and safety system (GMDSS) - Part 14: AIS search and rescue transmitter (AIS-SART) - Operational and performance requirements, methods of testing and required test results

IEC 61097-14:2010 specifies the minimum performance requirements, technical characteristics and methods of testing, and required test results, for Automatic Identification Systems (AIS) search and rescue transmitters (AIS-SART) which may be carried by ships as a search and rescue locating device as required by Chapters III and IV of the International Convention for Safety of Life at Sea (SOLAS), as amended. It takes account of IMO resolution A.694(17) and is associated with IEC 60945.

Système mondial de détresse et de sécurité en mer (GMDSS) - Partie 14: Emetteur de recherche et sauvetage AIS - Exigences opérationnelles et de fonctionnement, méthodes d'essai et résultats exigibles

L'IEC 61097-14:2010 spécifie les exigences de fonctionnement minimales, les caractéristiques techniques et méthodes d'essai, ainsi que les résultats exigés pour les essais en ce qui concerne les émetteurs de recherche et sauvetage à systèmes d'identification automatique (AIS - Automatic Identification Systems) (AIS-SAR) qui peuvent être embarqués sur des navires afin de constituer les dispositifs de recherche et sauvetage requis par les Chapitres III et IV de la Convention internationale pour la sauvegarde de la vie humaine en mer (SOLAS - International Convention for Safety of Life at Sea), dans sa version modifiée. Elle prend en compte la résolution OMI A.694(17) et est associée à l'IEC 60945.
