scope:

This International Standard specifies the functional requirements and recommended installation and performance tests for sound reception systems. Guidelines have been drawn up for the methods and solutions to meet the functional requirements. The requirements in the standard apply to fully enclosed bridges, and other bridges where such equipment is voluntarily installed. The purpose of the standard is to specify bridge requirements, which will secure a safe and efficient lookout on those seagoing ships having a fully enclosed bridge. The main use of this standard will be for designing of ship bridges. The standard will also be useful for a) specifiers and procurers of ships and bridge equipment, b) operators and owners for ensuring that changes made through the life of a ship still conform to its requirements. Users of this International Standard should note that while attempting to implement its requirements, they should ensure compliance with such statutory requirements, rules and regulations as may be applicable to the individual ship concerned. NOTE All requirements that are extracted from the recommendations of IMO Resolution MSC.86(70), annex 1, Performance standards for sound reception systems, are printed in italics and the resolution and paragraph numbers are indicated in brackets
