IEC 61097-2:2021(E) specifies the minimum performance requirements, technical characteristics and type-testing requirements of the emergency position-indicating radio beacon used in the Cospas-Sarsat satellite system (EPIRB), as required by the International Convention for Safety of Life at Sea (SOLAS) as amended, and which is associated with IEC 60945. When a requirement in this document is different from the requirements in IEC 60945 or other standards, the requirement in this document takes precedence.
This document incorporates the performance standards of IMO Resolution MSC.471(101), the International Telecommunication Union (ITU) Radio Regulations as well as the technical characteristics for such transmitters contained in Recommendation ITU-R M.633, and takes account of the general requirements contained in IMO Resolution A.694(17).
This document also includes minimum performance standards for a non-float-free EPIRB without float-free release mechanism (see Annex C).
The contents of the corrigendum of December 2021 have been included in this copy.

IEC 61097-3:2017 specifies the performance requirements, technical characteristics, operational requirements and methods of testing of shipborne DSC equipment for use with MF, MF/HF and VHF installations in the GMDSS, including those required by Chapter IV of the 1974 International Convention for Safety of Life at Sea (SOLAS) as amended, and is associated with IEC 60945 (Shipborne radio equipment forming part of the global maritime distress and safety system and marine navigational equipment).
This document incorporates applicable parts of the performance standards of IMO Resolutions A.803(19), A.804(19) and A.806(19) (DSC facilities for VHF, MF and MF/HF radio installations), IMO MSC/Circ.862 (describing the operation of the distress button), the provisions of the ITU Radio Regulations, the technical characteristics of DSC equipment and the operational procedures for its use contained in Recommendations ITU-R M.493, M.541, M.689, M.821 and M.1082, and takes into account the general requirements contained in IMO Resolution A.694(17).
This edition includes the following significant technical changes with respect to the previous edition:
a) changes in the operation of DSC which have been developed by IMO and ITU since the first edition was published;
b) compliance with bridge alert management (BAM);
c) optional addition of remote operation of the DSC functionality. This facility can also used for type approval testing of the performance of the DSC equipment;
d) incorporation of the radio frequency test methods for MF, MF/HF and VHF transceivers and watch receivers for convenience of testing.

Contains a series of revisions to IEC 60601-2-3 (second edition, 1991) taking into account amendments 1 and 2 of the General Standard, which include reference to the collateral standards.
