Maritime navigation and radiocommunication equipment and systems - Integrated navigation systems (INS) - Part 2: Modular structure for INS - Operational and performance requirements, methods of testing and required test results (IEC 61924-2:2021)

This part of IEC 61924 specifies the minimum requirements for the design, manufacture,
integration, methods of testing and required test results for an integrated navigation system
(INS) to comply with the International Maritime Organization (IMO) requirements of Resolution
MSC.252(83), as amended by Resolution MSC.452(99). In addition, it takes account of IMO
Resolution A.694(17) to which IEC 60945 is associated. When a requirement in this document
is different from IEC 60945, the requirement of this document takes precedence.
For bridge alert management, IMO Resolution MSC.302(87) supersedes IMO Resolution
MSC.252(83). Accordingly, this document incorporates references to IEC 62923-1 and
IEC 62923-2 which are associated with Resolution MSC.302(87) for requirements and tests,
where applicable. This document indicates which requirements and associated tests of
MSC.252(83) have been superseded by MSC.302(87).
NOTE All text of this document whose wording is identical to that in IMO Resolution MSC.252(83), as amended by
MSC.452(99), is printed in italics and the Resolution and paragraph number indicated between brackets.

IEC 61924-2:2021 est disponible sous forme de IEC 61924-2:2021 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 61924-2:2021 spécifie les exigences minimales applicables à la conception, à la fabrication, à l'intégration, aux méthodes d'essai et aux résultats d'essai exigés pour qu'un système de navigation intégré (INS - Integrated Navigation System) soit conforme aux exigences de la Résolution MSC.252(83) de l'Organisation Maritime Internationale (OMI), modifiée par la Résolution MSC.452(99). De plus, elle tient compte de la Résolution A.694(17) de l'OMI à laquelle est associée l'IEC 60945. Lorsqu'une exigence du présent document diffère de l'IEC 60945, l'exigence du présent document prévaut.
