Specifies the performance standards and type testing of marine radar transponders used in search and rescue operations at sea (SART), as required by Regulation 6.2.2 of Chapter III, and 7.1.3 and 8.3.1 of Chapter IV of the 1988 amendments to the 1974 International Convention for Safety of Life at Sea (SOLAS). Is associated with IEC 60936 and IEC 60945. This new edition takes into account changes to the IMO performance standards for the SART in resolution A.802(19).
