1 Scope

This standard specifies the functional requirements, recommended installation and performance tests of the sound receiving system, and provides methods and solutions to meet the functional requirements.

Guide to the solution.

These requirements apply to fully enclosed bridge buildings and other bridge buildings that voluntarily install such equipment.

This standard specifies the requirements for ensuring safe and effective observation of bridges on seagoing vessels with fully enclosed bridges.

This standard applies to the design of ship bridges. It also applies to.

a) Ship and bridge equipment ordering and purchasing personnel;

b) Operators and shipowners ensure that the changes made during the life of the ship still meet their requirements.
