Overview
IEC 60050-826:2004 is an integral part of the International Electrotechnical Vocabulary (IEV) series published by the International Electrotechnical Commission (IEC). This specific part, titled Electrical Installations, provides standardized terminology for electrical installations across various types of premises including residential, industrial, and commercial environments. It is recognized as a horizontal standard per IEC Guide 108, meaning its scope extends broadly and applies horizontally across multiple sectors in the electrotechnical field.
This second edition, published in August 2004, updates and replaces the original 1982 edition and its subsequent amendments. It aims to ensure consistent international understanding, communication, and application of key terms and concepts related to electrical installations.
Key Topics
IEC 60050-826:2004 is organized systematically into distinct sections covering comprehensive aspects of electrical installations. The key topics include:
-
Characteristics of Electrical Installations (Section 826-10)
Defines fundamental properties and attributes relevant to electrical installations’ design and operation.
-
Voltages and Currents (Section 826-11)
Standardized terms describing the electrical quantities essential for system functionality.
-
Electric Shock and Protective Measures (Section 826-12)
Terminology related to hazards from electrical shock and corresponding safety measures.
-
Earthing and Bonding (Section 826-13)
Common definitions for grounding systems and equipotential bonding critical for protection and operation.
-
Electric Circuits (Section 826-14)
Terms for circuit types, configurations, and elements used in installation design.
-
Wiring Systems (Section 826-15)
Descriptions related to wiring methods, cabling, and conduit systems.
-
Other Equipment (Section 826-16)
Covers additional components used within electrical installations not classified elsewhere.
-
Isolation and Switching (Section 826-17)
Terminology associated with disconnecting devices and switching mechanisms to control installations.
-
Capability of Persons (Section 826-18)
Definitions concerning the competence and qualifications required for personnel working on electrical installations.
Each entry in the vocabulary is multilingual, featuring terms in English, French, and additional languages such as Arabic, Chinese, German, Spanish, and others, facilitating global applicability.
