Overview
IEC 60050-826 Amendment 3 is a key update to the International Electrotechnical Vocabulary (IEV), specifically focusing on Chapter 826: Electrical Installations of Buildings. Published in April 1999 by the International Electrotechnical Commission (IEC), this amendment refines terminology and definitions related to electrical supply systems essential for safety and standby power in buildings. The document was prepared by IEC Technical Committee 64 on Electrical Installations of Buildings, under the guidance of Technical Committee 1 for Terminology.
This standard plays a critical role in harmonizing language used internationally in the design, operation, and regulation of electrical installations within buildings, advancing safety and reliability in critical power supply systems.
Key Terms and Topics
IEC 60050-826 Amendment 3 introduces and modifies key vocabulary entries that cover essential safety and operational systems:
Electric Supply System for Safety Services (826-01-05)
A supply system designed to ensure continuous operation of equipment critical for:- Protecting health and safety of persons
- Preventing major environmental damage or equipment losses when mandated by regulations
This system includes the source and circuits up to the equipment terminals, and sometimes the equipment itself.
Safety Electric Source (826-01-07)
The designated electrical source intended specifically to maintain power supply exclusively for safety service equipment.Standby Electric Supply System (826-01-06)
A backup electrical supply maintaining normal functioning of installations or parts thereof during interruptions, for reasons other than safety.Standby Electric Source (826-01-08)
A source providing power to installations or parts of installations during normal supply interruptions, excluding safety reasons.
These clarified definitions are vital for architects, electrical engineers, safety inspectors, and regulatory bodies who handle the planning, installation, testing, and maintenance of electrical systems in residential, commercial, and industrial buildings.
Applications
IEC 60050-826 Amendment 3 supports a broad range of practical applications including:
Building Electrical Design: Provides standard terminology aiding in specification and communication when designing electrical supply systems catering to safety and standby needs.
Safety Compliance and Regulation: Offers clear definitions aiding regulators and inspectors in verifying that buildings comply with safety power supply requirements, crucial for fire alarms, emergency lighting, and evacuation systems.
Emergency Power Systems: Helps in defining roles of electrical sources and supply systems during power outages, ensuring proper integration of generators, uninterrupted power supplies (UPS), and battery systems.
Facility Management and Maintenance: Assists facility managers in understanding and managing electrical installation risks, ensuring continuous power for critical safety systems to protect occupants and property.
Interdisciplinary Communication: Establishes unified vocabulary fostering clearer collaboration between engineers, architects, safety professionals, and regulators across different countries and languages.
Related Standards
For comprehensive application and compliance, IEC 60050-826 Amendment 3 complements other international standards including:
- IEC 60364 Series – Electrical Installations for Buildings; focuses on design, verification, and safety requirements.
- IEC 61508 – Functional Safety of Electrical/Electronic/Programmable Electronic Safety-Related Systems.
- IEC 62040 – Uninterruptible Power Systems (UPS), relevant for standby electric sources.
- ISO 7010 – Safety Signs, relating to safety installations powered by these electrical supply systems.
These interconnected standards collectively ensure globally consistent safety, performance, and reliability of electrical installations in buildings.
