SIST ETS 300 441:1999/A1:1999

Overview

SIST ETS 300 441:1999/A1:1999 is a Slovenian standard that defines the technical characteristics and measurement methods for maritime radiotelephone watch receivers operating on the international distress and calling frequency of 2 182 kHz. Developed by the Electromagnetic Compatibility and Radio Spectrum Matters (ERM) Technical Committee and aligned with ETR 238, this standard aims to ensure that maritime communication equipment meets regulatory requirements for electromagnetic compatibility (EMC) under the EMC Directive (89/336/EEC). This amendment brings the previous standard in line with European harmonized standards, supporting publication in the Official Journal of the European Communities.

Key Topics

• Electromagnetic Compatibility (EMC): The standard outlines requirements to minimize electromagnetic interference, ensuring reliable operation of maritime radio equipment while preventing harmful emissions.
• Technical Characteristics: It details essential performance parameters for radiotelephone watch receivers, such as blocking, spurious response rejection ratio, and spurious emissions, which are critical for receiver reliability and operational safety.
• Measurement Methods: The document specifies consistent and repeatable methods for assessing receiver compliance, supporting uniform testing across manufacturers and conformity assessment bodies.
• Harmonization and Compliance: SIST ETS 300 441:1999/A1:1999 is designed to align national regulations with European Directives, enabling harmonization and facilitating free circulation of compliant maritime equipment within the European Union.

Applications

SIST ETS 300 441:1999/A1:1999 serves as a technical reference for:

• Manufacturers of Maritime Radio Equipment: Ensuring radiotelephone watch receivers conform to EMC and radio spectrum requirements, which is necessary for regulatory approval and market access in the EU.
• Maritime Vessel Operators: Assuring that onboard distress and calling communications equipment meets recognized safety and compatibility standards, thereby supporting reliable emergency communications at sea.
• Conformity Assessment Bodies: Providing a basis for testing and certifying equipment for compliance with EU regulations and directives, including the EMC Directive.
• Regulatory Authorities: Assisting in the evaluation and enforcement of technical compliance for maritime distress radio equipment, contributing to safe and effective maritime communication systems.

Related Standards

• EN 301 090: Complements SIST ETS 300 441 by defining additional requirements and is referenced for harmonization within the EU.
• ETR 238: The revision aligns with the technical guidelines in ETR 238, ensuring consistency with broader European radio standards.
• Council Directive 89/336/EEC (EMC Directive): Provides the regulatory framework for electromagnetic compatibility in the EU, which is directly referenced by this standard.
• Other Maritime Equipment Standards (ICS 33.060.99, 47.020.70): Relevant for manufacturers and operators seeking comprehensive compliance in radiocommunication and navigation equipment.
