Specifies the environmental, operational and radiofrequency requirements for 121.5 and 243.0 MHz emergency position indicating radio beacons (EPIRBs) including personal EPIRBs used in marine and aviation portable applications.

This Standard provides the minimum requirements for maritime emergency position indicating radio beacons (EPIRBs) including those designed for use as personal EPIRBs operating with carrier frequencies of 121.5 and 243.0 MHz and aviation portable emergency locater transmitters (ELTs) operating on 121.5 MHz.These requirements encompass the physical characteristics of the devices, as they pertain to maritime use, and the performance characteristics for reception through a space satellite system or by overflying aircraft.This Standard does not apply to fitted emergency locating transmitters (ELTs) or 406 MHz beacons employing 121.5 or 243.0 MHz homing devices.Unless otherwise stated, aviation portable ELTs shall meet the same technical requirements as personal EPIRBs.
