IEC TR 61149-1995 PDF

Full title and description

IEC 61149:1995 — Guide for safe handling and operation of mobile radio equipment. Bilingual publication (English/French) providing guidance and recommended practices for the safe operation, handling and maintenance of mobile radio transmitters, associated ancillary equipment, feeder-lines and antenna systems used in mobile and vehicular radio installations.

Abstract

This publication gives practical guidance to reduce hazards to personnel arising from the operation and maintenance of mobile radio equipment. It addresses safe working distances, installation and mounting of equipment and antennas, feeder-line and connector safety, control and interconnection circuits, and procedures for routine servicing and emergency situations. The document is intended as a safety-oriented guide rather than a prescriptive performance specification.

General information

• Status: Published by the International Electrotechnical Commission. Cataloguing varies (listed as IEC/TS 61149 by the IEC webstore and described as a Technical Report — type 2 — in several national catalogues).

• Publisher: International Electrotechnical Commission (IEC).
• ICS / categories: 33.060.30 (Radio relay and fixed satellite communications systems); 13.110 (Safety of machinery) — reflects the safety and radiocommunication subject areas.
• Edition / version: Edition 1.0 (1995).
• Number of pages: 47 pages (standard PDF/paper publication length listed by the IEC webstore and national distributors).

Scope

The guide applies to all mobile radio equipment and auxiliary apparatus used in mobile and vehicular radiocommunication installations, including combining units, matching networks, antenna systems and associated feeder-lines, plus remote control and interconnecting telephone circuits where applicable. Its intent is to identify hazards and provide safe-handling and operational recommendations for personnel involved in installation, routine operation and maintenance.

Key topics and requirements

• Identification of hazards associated with RF energy, high-voltage components, battery systems and moving vehicle installations.
• Recommended safe working distances and positioning for personnel when transmitters or antennas are operating.
• Safe installation and grounding practices for antennas, feed lines and vehicle-mounted equipment.
• Procedures for connecting, disconnecting and servicing equipment to avoid inadvertent transmitter operation and exposure.
• Guidance on signage, warnings, labelling and administrative controls (procedures, training, permit-to-work) for maintenance tasks.
• Recommendations for handling batteries, fuel-powered generators and other auxiliary systems commonly associated with mobile installations.
• Emergency procedures and verification steps following antenna or feeder-line faults, lightning strikes or collision damage.

Typical use and users

Used by equipment manufacturers, installation contractors, maintenance engineers, safety officers, radio network operators and regulators. It serves as a practical reference for developing site-specific safe working procedures, training materials and inspection checklists for mobile and vehicular radio installations.

Related standards

Complementary guidance and requirements will often be sought from other IEC standards on electromagnetic exposure and measurement (for example standards addressing human exposure limits and SAR measurement), EMC and surge/lightning protection, plus national occupational safety regulations and vehicle-safety standards. Users commonly consult these in combination with IEC 61149 guidance when creating complete safety and compliance programs.
