Full title and description

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. This standard defines minimum operational and performance requirements, test methods and required test results for integrated navigation systems to meet applicable International Maritime Organization (IMO) performance standards.

Abstract

IEC 61924-2:2021 (Edition 2.0) specifies requirements for the design, manufacture, integration and testing of Integrated Navigation Systems (INS). It clarifies a modular INS structure, details module-specific requirements (integration of navigational information, task-related functions, alert management and documentation), and aligns required tests and results with IMO resolutions governing bridge alert management and INS performance.

Scope

IEC 61924-2:2021 applies to Integrated Navigation Systems (INS) and specifies the minimum requirements for their modular design, functional performance, integration and documentation, together with the methods of testing and the test results required to demonstrate compliance. The standard is written to ensure conformity with IMO performance standards (notably Resolution MSC.252(83) as amended and related updates) and takes account of related IEC and IMO documents addressing bridge alert management and interface requirements.

Key topics and requirements

• Modular INS structure and module definitions (integration of navigational information, task-related functions, alert management, documentation).
• Operational and performance requirements for INS functions and user tasks on the bridge.
• Test methods and required test results to verify compliance (type tests, functional tests and documented evidence).
• Bridge alert management (alignment with BAM requirements and the use of referenced standards for alert identifiers and handling).
• Interfaces and interoperability requirements between INS components and other shipborne systems.
• Documentation, labeling and manufacturer-supplied information required for conformity assessment and installation.
• Identification of which IMO/earlier requirements have been superseded and references to related IEC performance standards.

Typical use and users

Used by manufacturers of maritime navigation equipment, system integrators, shipyards, classification societies, testing laboratories, flag administrations and ship operators. It supports design and type-approval of INS, verification testing, conformity assessment for SOLAS/MED requirements and national or regional adoption (for example EN adoption).

Related standards

Typical related publications include IEC 60945 (general requirements and tests for maritime navigation equipment), IEC 62923-1 and IEC 62923-2 (Bridge Alert Management), IEC 61162 series (digital navigational data interfaces), the previous edition IEC 61924-2:2012 (withdrawn), and relevant IMO resolutions such as MSC.252(83), MSC.302(87) and MSC.452(99). Regional/European adoption appears as EN IEC 61924-2:2021.

FAQ

Q: What is this standard?

A: IEC 61924-2:2021 is the international performance and testing standard for Integrated Navigation Systems (INS) that defines a modular structure, operational and performance requirements, and required methods and results for testing.

Q: What does it cover?

A: It covers minimum requirements for design, manufacture, integration, functional performance, bridge alert management and the specific methods of testing and required test results needed to demonstrate compliance with IMO performance standards and associated IEC requirements.

Q: Who typically uses it?

A: Manufacturers of navigation equipment, system integrators, shipyards, classification societies, testing laboratories, maritime administrations and ship operators use it for product design, type approvals, conformity assessment and installation guidance.

Q: Is it current or superseded?

A: IEC 61924-2:2021 was published on 12 February 2021 (Edition 2.0) and replaces IEC 61924-2:2012. As published by IEC it is the current edition; the IEC publication record lists a stability date indicating the document is expected to remain stable through 2027.

Q: Is it part of a series?

A: Yes — it is Part 2 of IEC 61924 (the IEC 61924 base number relates to integrated navigation systems). It is also used together with other maritime standards (for example IEC 60945 and the IEC 62923 series for bridge alert management) and has regional/adopted variants such as EN IEC 61924-2:2021.

Q: What are the key keywords?
