ISO 16425 pdf download Ships and marine technology — Guidelines for the installation of ship communication networks for shipboard equipment and systems
Scope
This International Standard specifies installation guidelines for ship communication networks forimproving communication for shipboard equipment and systems that are independentfrom navigationalequipment networks and engine-control networks.
This International Standard utilizes existing standards relating to protocols, and provides newguidelines for such aspects as communication network-system architecture, administration, operationand installation.
The new guidelines specifically include: redundancy if necessary for a shipboard communicationnetwork system; network adminstration that does not require experts: physical as well as logicasecurity; and networkinstallation.
