【正文】 er equipment installed on and around the bridge of a ship with regard to EMC. A new class of equipment – ―portable‖ – was added, together with better definitions of operational tests which involve subjective judgement and descriptions of operational and durability aspects of software. This fourth edition (now IEC 60945) extends the detail of operational tests particularly for equipment which is operated through software menus. This has been derived from an exhaustive investigation of appropriate references as described in the Bibliography. The layout of clause 4 (Minimum performance requirements) has been changed to give a better grouping of ergonomics, hardware and software requirements. The EMC tests have been revised with the frequency range having been extended from 1 GHz to 2 GHz. Clarifications to the text of the third edition have been added where experience has shown a need and the references have been updated. A parison of the test requirements in the third and fourth editions is given in annex G to assist manufacturers and test houses in the use of the new edition.

(Administrations are defined by the IMO as governments of the states whose flags the ships are entitled to fly.) The performance standard for general requirements for shipborne radio equipment and electronic navigation aids that has been adopted by the IMO is given in IMO Resolution and is reproduced in this standard as annex A, which forms the basis for this standard. Reference is made, where appropriate, to IMO Resolutions and and all subclauses whose wording is identical to that in the resolutions are printed in italics. This standard specifies minimum performance requirements, methods of testing and required test results for general requirements which can be applied to those characteristics mon to all equipment described hereunder: a) shipborne radio equipment forming part of the global maritime distress and safety system required by the International Convention for Safety of Life at Sea (SOLAS) as amended, and by the Torremolinos International Convention for the Safety of Fishing Vessels as amended。 Europ233。te und systeme f252。rales M233。riels et syst232。 — monitor related international and European developments and promulgate them in the UK.
