Description (English):

Specifies the minimum performance requirements, technical characteristics and type-testing requirements of the satellite emergency position-indicating radio beacon used in the COSPAS-SARSAT satellite system (satellite EPIRB), as required by the International Convention for Safety of Life at Sea (SOLAS). Is associated with IEC 60945 and incorporates the performance standards of the relevant IMO Resolutions and ITU Regulations. Significant changes in this third edition include revised characteristics for the low duty cycle light, together with a revised test to allow the use of white LEDs. Other requirements have been clarified or revised as well.

Abstract

Overview

IEC 61097-2:2008 defines the operational and performance requirements, test methods, and required test results for COSPAS‑SARSAT satellite emergency position‑indicating radio beacons (EPIRBs) operating on 406 MHz. Part of the Global Maritime Distress and Safety System (GMDSS) family, this standard supports SOLAS compliance by specifying minimum technical characteristics and type‑testing needed for satellite EPIRB type approval and safe maritime distress signalling.

Key topics and technical requirements

Scope and compliance: Minimum performance requirements and type‑testing for 406 MHz satellite EPIRBs used with COSPAS‑SARSAT; intended for SOLAS applications and regulatory type approval.
Distress signalling: Requirements for the 406 MHz distress message format, beacon identification codes and distress message memory.
Homing signal: Specification and test requirements for the 121.5 MHz homing transmitter (referenced technical standard in Annex D).
Operational features: Controls and ergonomics (prevention of inadvertent activation, activation, self‑test, indication of previous activation, colour/retro‑reflective materials, lanyard).
Float‑free arrangements: Design, release mechanisms, manual and automatic release checks and tests for float‑free EPIRBs.
Power and battery: Battery life, expiry date marking and low‑temperature performance tests; reverse polarity protection.
Antenna and emissions: Antenna characteristics, spurious emissions and homing signal masks.
Environment and ruggedness testing: Temperature, icing, shock, vibration, immersion, solar radiation, oil resistance and corrosion - many tests align with IEC 60945 environmental tests.
Electromagnetic compatibility (EMC): Requirements to limit interference and conducted emissions.
Testing methodology: Detailed test sequences, preparation for COSPAS‑SARSAT type approval, and pass/fail criteria (annexed test sequences and procedural details).
Updates in Edition 3: Revised low‑duty‑cycle light characteristics and updated tests to allow use of white LEDs; other clarifications and revisions throughout.

Applications and who uses this standard

IEC 61097-2 is used by:

EPIRB manufacturers for product design, development and pre‑compliance testing.
Certification bodies and test laboratories performing COSPAS‑SARSAT type approval and SOLAS certification.
Shipbuilders, ship operators and procurement teams specifying compliant emergency beacons for vessels.
Maritime safety authorities, flag states and classification societies enforcing regulatory compliance.
Maritime equipment integrators and maintenance providers for installation, servicing and lifecycle checks.

Practical uses include design verification, type approval testing, installation guidance, maintenance schedules and regulatory compliance documentation.

Related standards

IEC 60945 - Environmental and performance tests for shipborne equipment (referenced for many environmental tests).
SOLAS (IMO) - Regulatory requirement tying EPIRB performance to maritime safety law.
Relevant IMO Resolutions and ITU Regulations - Incorporated for signal formats, frequencies and international radio rules.
