Video of EPIRB Testing by Iron Unidec and EPIRB Tester Mini

Category: EPIRB

Today we will perform the comparative tests of EPIRB, which is intended to detect and locate the boards, aircrafts and people in distress. 

EPIRBs shall be tested at intervals not exceeding 12 months for all aspects of operational efficiency with particular emphasis on frequency stability, signal strength and coding. Today we will check all these parameters.

We need to perform electrical tests to confirm the EPIRB is operational as defined in appropriate performance standards. And for these purposes we require the suitable test equipment – EPIRB Tester. Complete volume of the tests is described in IMO Circular 1040.

Video of annual testing of Cospas-Sarsat EPIRB by Futronic Test Box

Category: EPIRB

Today we will perform the annual testing of Cospas-Sarsat EPIRB as it is required by SOLAS convention. The volume and order of the tests are described in IMO Circular 1040 and we will follow it.

We need to perform electrical tests to confirm the EPIRB is operational as defined in appropriate performance standards. And for these purposes we require the suitable test equipment - EPIRB Tester. 

Fortunately, we have 3 testers today: Futronic made by Danphone, and two testers made by Musson Marine Ltd: Beacon Tester and Beacon Tester Mini.

Servicing and testing of 406MHz EPIRBs

Category: EPIRB

Marine Orders requires that a 406 MHz EPIRB is tested and, if necessary has its batteries replaced at intervals specified by the manufacturer. Hydrostatic releases must be replaced by their expiry dates. These are usually marked on the release mechanism. 


406 MHz EPIRBs are to be physically examined and the self-test function checked, at least once per month.

The EPIRB is subject to annual performance tests under SOLAS regulation IV/15.9: "Satellite EPIRBs shall be tested at intervals not exceeding 12 months for all aspects of operational efficiency with particular emphasis on frequency stability, signal strength and coding" and shore-based maintenance at intervals not exceeding five years.

EPIRB Testing

The purpose of an annual testing is to determine that EPIRB is operational as defined in appropriate performance standards - the International Maritime Organization (IMO) Performance Standard (A.810) and IEC standard, IEC 61097-2: COSPAS-SARSAT EPIRB – Satellite emergency position indicating radio beacon operating on 406 MHz – Operational and performance requirements, methods of testing and required test results.

The annual testing of 406 MHz satellite EPIRBs is required by SOLAS regulation IV/15.9. The volume of annual beacon testing is described in IMO MSC.1/Circular 1040. MSC/Circ.955 further recommends that annual testing of the EPIRB shall be carried out concurrently with the Annual Safety Radio Survey. Shore-based maintenance volume is described in IMO MSC/Circ.1039.

The testing should be carried out using suitable test equipment, such as EPIRB Tester, capable of performing all the relevant measurements required in these guidelines. All checks of electrical parameters should be performed in the self-test mode, if possible.
