SIST EN 300 152-1 V1.2.2:2003 is the SIST adoption of the ETSI European Standard for Maritime Emergency Position Indicating Radio Beacons (EPIRBs) used on 121,5 MHz or on 121,5 MHz and 243 MHz for homing purposes only. It specifies the technical characteristics and methods of measurement for these beacons, mainly for manufacturers, test laboratories, and conformity assessment or type-approval bodies working with maritime search and rescue equipment.
What does SIST EN 300 152-1 V1.2.2:2003 specify?
SIST EN 300 152-1 V1.2.2:2003 sets minimum requirements for EPIRBs that transmit on the specified homing frequencies and includes the measurement methods used to verify them. The scope also covers very short range man-overboard location applications, where reduced radiated power and operating time are allowed so the equipment can stay small and light enough to wear.
The document is organized around construction and labeling requirements, transmission and battery requirements, measurement conditions, environmental tests, and radio-radiation tests. It also has one normative annex for radiated measurements.

What are the key requirements of SIST EN 300 152-1 V1.2.2:2003?
SIST EN 300 152-1 V1.2.2:2003 focuses on a beacon that is simple to use in an emergency, resistant to harsh marine conditions, and measurable in a repeatable way. The most important requirements are in clauses 4 to 8.
Construction and operation
Clause 4 requires a portable, lightweight, compact, single-unit EPIRB with a battery built into the equipment and a permanently attached antenna. It must be watertight, buoyant, visibly colored, and suitable for use by an unskilled person. In practice, this means the beacon should survive handling and be easy to find, activate, and operate when there is little time.
Activation, indicators, and marking
Clause 4.2 requires initial activation by two simple, independent mechanical actions, with an immersion sensor allowed only for man-overboard devices. The test facility must not break the security seal, and the test switch must return to off when released. Clause 4.3 requires a visual signal when the transmitter is active, and clause 4.4 requires permanent labels showing the operating frequency or frequencies, serial number, type designation, battery type, emergency-only warning, and battery replacement date. This helps crews and inspectors confirm the right unit, battery, and operating status.
Power source and transmission
Clause 4.6 requires protection against accidental battery polarity reversal. Clause 5.1 requires continuous transmission on 121,5 MHz or on both 121,5 MHz and 243 MHz, with emission class A3X. Clause 5.2.1 requires a primary battery with enough capacity for at least 24 hours of operation, or at least 6 hours for man-overboard devices only, under all temperature conditions. That is what makes the beacon useful through long searches and difficult weather.
Measurement and environmental verification
Clause 6 defines the test fixture, test conditions, and measurement uncertainty, so results can be compared reliably. Clauses 7 and 8 then check survival in drop, temperature, vibration, corrosion, thermal shock, buoyancy, solar radiation, oil, and transmitter-protection tests, plus frequency error, modulation, spectral carrier power ratio, ERPEP, and spurious emissions. Clause 7.3 adds a performance check after environmental testing, including a carrier-frequency check and minimum output-power checks.
What terms does SIST EN 300 152-1 V1.2.2:2003 define?
- Emergency Position Indicating Radio Beacon (EPIRB) - A station in the maritime mobile service whose emissions are intended to support search and rescue operations.
- Homing device - A 121,5 MHz/243 MHz beacon primarily intended for transmitting homing signals.
- Effective Radiated Peak Envelope Power (ERPEP) - The peak-envelope radiated power in the direction of maximum field strength.
- Radio Frequency (RF) - The radio-frequency domain used for the transmitter, test fixture, and measurement methods.
- A3X - The emission class required for the EPIRB transmission.
- EPIRB station - The document’s term for the beacon as a station in the maritime mobile service.
Who uses SIST EN 300 152-1 V1.2.2:2003?
SIST EN 300 152-1 V1.2.2:2003 is used by EPIRB manufacturers, marine equipment suppliers, test laboratories, and testing authorities. It is also relevant to quality managers and buyers who need to verify that a beacon design matches the required frequencies, battery endurance, environmental resistance, and measurement methods. Maritime regulators and type-approval teams use it to check conformity for search and rescue equipment.
What changed in SIST EN 300 152-1 V1.2.2:2003 from the previous edition?
SIST EN 300 152-1 V1.2.2:2003 is described as an editorial update consequent to the creation of Part 2. The foreword identifies it as Part 1 of a multi-part EN, with Part 2 covering the harmonized EN under article 3.2 of the R&TTE Directive and Part 3 covering the harmonized EN under article 3.3e.
Which standards are used with SIST EN 300 152-1 V1.2.2:2003?
SIST EN 300 152-1 V1.2.2:2003 cites ITU-R Recommendation M.690-1 for EPIRB technical characteristics, and it uses ETSI ETR 028 for measurement uncertainty. It also refers to ETSI ETR 273 for radiated measurement methods and uncertainties, and to Directive 98/34/EC for the standardization procedure mentioned in the introduction. These references support the measurement setup, uncertainty handling, and the radio-service context of the EPIRB requirements.
What does the SIST EN 300 152-1 V1.2.2:2003 document contain?
SIST EN 300 152-1 V1.2.2:2003 contains clause-by-clause requirements for construction, controls, indicators, labeling, batteries, test conditions, environmental endurance, and radio performance. It also contains measurement procedures for frequency error, modulation depth, modulation duty-cycle, sweep characteristics, spectral carrier power ratio, ERPEP, radiation from the test facility, and spurious emissions.
The document includes a test-fixture description, uncertainty limits, and a modulation figure used to calculate depth and duty-cycle. Annex A provides radiated-measurement arrangements for outdoor sites, optional indoor sites, anechoic chambers, and the standard position used during testing.
