Overview

SIST EN 300 152-1 V1.2.2:2003 addresses the technical characteristics and methods of measurement for maritime Emergency Position Indicating Radio Beacons (EPIRBs) intended for use on 121.5 MHz, or both 121.5 MHz and 243 MHz, specifically for homing purposes. Developed by the Slovenski inštitut za standardizacijo (SIST), this standard aligns with key European and international regulations regarding electromagnetic compatibility (EMC) and radio spectrum management, ensuring compliance and interoperability in maritime safety equipment.

EPIRBs are essential in maritime distress situations, transmitting radio signals that support search and rescue operations. This part of the standard specifies requirements for the construction, performance, and testing of EPIRBs, including environmental resilience and identification labelling, and incorporates relevant provisions from ITU and ICAO standards.

Key Topics

• Scope and Objectives

  • Defines minimum performance and construction requirements for EPIRBs operating on 121.5 MHz or both 121.5 MHz and 243 MHz.
  • Focuses on beacons intended exclusively for homing signals to assist in locating vessels, survival craft, and man-overboard situations.
  • Editorial updates reflect recent developments with the creation of Part 2.

• Technical Requirements

  • Specifications for frequency stability and transmission characteristics.
  • Battery and power source requirements, ensuring reliable performance for specified durations under normal and extreme conditions.
  • Controls demanding simple, two-stage manual activation for general use, with immersion sensors permitted for man-overboard applications.
  • Strict construction guidelines for durability, buoyancy, watertightness, visibility (yellow/orange color), and resistance to environmental factors.

• Testing and Measurement

  • Methods for verifying transmission performance, including frequency, power output, modulation, and spurious emissions.
  • Environmental robustness through vibration, drop, temperature, corrosion, solar radiation, oil resistance, and thermal shock testing.
  • Measurement uncertainty guidelines ensuring test accuracy, as referenced in related ETSI technical reports.

• Labelling and User Information

  • Mandatory labelling for frequency, serial number, battery type, battery replacement date, and user instructions.
  • Warnings against non-emergency usage.

Applications

The standard is directly applicable to:

• Maritime EPIRB Manufacturers and Designers: Ensuring products meet the required technical and safety specifications for global markets.
• Conformity Assessment Bodies and Testing Laboratories: Establishing a framework for consistent evaluation, approval, and certification of EPIRB equipment.
• Ship Operators and Maritime Safety Authorities: Guaranteeing that emergency beacons installed onboard are reliable, compliant, and ready for deployment during distress operations.
• Rescue Coordination Centers: Reliable beacon operation supports rapid identification and location of distress signals, greatly enhancing search and rescue effectiveness.
• Personal Man-Overboard Devices: Standards for compact, wearable beacons used in short-range, immediate rescue scenarios.

Following the standard helps stakeholders reduce risk, comply with European and international law, and improve overall maritime safety.

Related Standards

For comprehensive compliance and broader context, consider the following standards:

• EN 300 152-2: Harmonized standard covering essential requirements under the R&TTE Directive.
• ITU-R Recommendation M.690-1: Technical characteristics of emergency position-indicating radio beacons.
• ETSI ETR 028: Guidelines on uncertainties in the measurement of mobile radio equipment.
• ETSI ETR 273: Improvement of radiated measurement methods and evaluation of uncertainty.
• Relevant ICAO Standards: For aviation-related search and rescue interoperability.
• National Maritime Safety Regulations: Local standards may incorporate or reference SIST EN 300 152-1 for type approval.

By adhering to SIST EN 300 152-1 V1.2.2:2003, manufacturers, operators, and authorities contribute to a standardized, interoperable maritime distress signalling ecosystem, enhancing safety for seafarers worldwide.
