SIST EN 61162-3:2008/A1:2010

SIST EN 61162-3:2008/A1:2010 is the Slovenian adoption of the European amendment to IEC 61162-3 for maritime navigation and radiocommunication equipment and systems. It updates the serial data instrument network used to connect marine electronic equipment on vessels, based on NMEA 2000. For engineers, buyers and test teams, it tells you which network database reference to use and which AIS Class B message entries were added.

What does SIST EN 61162-3:2008/A1:2010 specify?

SIST EN 61162-3:2008/A1:2010 is an amendment to EN 61162-3:2008. It keeps the base Part 3 framework for a serial-data communications network for marine electronic equipment, and it updates the normative reference to the NMEA 2000 database used by that network.

The base Part 3 is described as a network for short data messages that can carry data, commands and status over a single signalling channel. It is aimed at items such as position, GPS status, steering commands, waypoints and moderate database updates, not at radar, electronic chart video or other heavy file-transfer uses.

What are the key requirements of SIST EN 61162-3:2008/A1:2010?

The technical change in this amendment is in Clause 2 and Annex ZA: the referenced NMEA 2000 Appendix B is replaced by Version 1.300: May 2009. In practice, anyone implementing or checking a compliant system needs to use the later database reference named here.

The introduction to Amendment 1 says the updated NMEA 2000 Appendix B adds five new sentences for AIS Class B. Those added PGN entries are relevant when equipment must exchange AIS Class B-related data using the network database named by the standard.

The scope states that IEC 61162-3 defines the necessary layers of the ISO/OSI model from the application layer to the physical layer. In practice, this means the standard is not only about message content, but also about how devices format, send and receive those messages on the network.

The scope also says the network is intended for brief messages that may be periodic, on-demand or sent in response to query commands. That matters because implementers can plan for command, status and parameter exchange, but should not treat this network as a broadband media link.

For SOLAS applications, the scope calls for redundant designs such as dual networks or redundant interface circuits. In practice, ship designers need to think about single-point failures and provide backup paths where the installation is safety-critical.

Annex A gives guidance on shipboard installation design, while the standard itself stays focused on network functionality and interface definition. That helps installers and integrators separate the network specification from the wider ship design decision.

What terms does SIST EN 61162-3:2008/A1:2010 define?

• NMEA 2000 - The serial-data network standard that the base Part 3 is based upon, and the database reference updated by this amendment.
• PGN - The numbered message identifier used in the updated NMEA 2000 Appendix B entries listed in the amendment.
• AIS Class B - The group of AIS message entries added by the updated appendix reference in Amendment 1.
• SOLAS - The ship safety context in which the scope calls for redundant designs to reduce single-point failures.
• CENELEC - The European electrotechnical committee that approved the amendment as a European Standard.
• IEC 61162-3 - The IEC part that specifies the serial data instrument network for maritime navigation and radiocommunication equipment.

Who uses SIST EN 61162-3:2008/A1:2010?

Manufacturers of marine navigation and radiocommunication equipment use this standard when designing devices that share data over the serial-data instrument network. System integrators and shipyards use it when connecting compatible onboard equipment to the same signalling channel.

Test laboratories and certification teams use it to check that equipment follows the named NMEA 2000 database reference and supports the expected message set. Buyers and technical managers use it to confirm that a product is meant for brief marine data exchange, not for radar or other high-bandwidth applications.

It is also relevant to ship operators and designers working on SOLAS-related installations, because the scope points to redundant network design for safety-critical use.

What changed in SIST EN 61162-3:2008/A1:2010 from the previous edition?

SIST EN 61162-3:2008/A1:2010 is Amendment 1 to EN 61162-3:2008. The amendment updates the normative reference from NMEA 2000, Appendix B, Version 1.210: September 2006 to NMEA 2000, Appendix B, Version 1.300: May 2009, and the introduction states that the later version adds five AIS Class B-related sentences.

Which standards are used with SIST EN 61162-3:2008/A1:2010?

The amendment names NMEA 2000, Appendix B, Version 1.300: May 2009, Serial-Data Networking Of Marine Electronic Devices - Data Base. This reference provides the database content used by the network, including the updated AIS Class B entries.

What does the SIST EN 61162-3:2008/A1:2010 document contain?

The document contains the amendment front matter, the foreword, and an endorsement notice showing that CENELEC approved the IEC text without modification. It also contains an introduction to Amendment 1 explaining the purpose of the update.

Clause 2 replaces the earlier NMEA 2000 database reference, and Annex ZA gives the corresponding normative reference table. The technical effect of the document is concentrated in that reference update and the new AIS Class B entries named in the introduction.
