IEC 61097-2:20 21（E）规定了Cospas-Sarsat卫星系统（EPIRB）中使用的紧急位置指示无线电信标的最低性能要求、技术特性和型式试验要求，符合经修订的《国际海上人命安全公约》（SOLAS）的要求，并与IEC 60945相关联。当本文件中的要求与IEC 60945或其他标准中的要求不同时，以本文件中的要求为准。 本文件纳入了IMO决议MSC.471(101)的性能标准、国际电信联盟(ITU)无线电法规以及ITU-R M.633建议中包含的此类发射机的技术特性，并考虑了IMO决议A.694(17)中包含的一般要求。 本文件还包括无浮动释放机制的非无浮动EPIRB的最低性能标准（见附录C）。

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).
