What is IEC 60479?

With the rapid development of technology, the need for safety standards and regulations has become increasingly important. One such standard that plays a crucial role in ensuring electrical safety is IEC 60479.

History and Purpose

IEC 60479, also known as "Effects of current on human beings and livestock - Part 1: General aspects," is an international standard published by the International Electrotechnical Commission (IEC). It was first introduced in 1973 and has been regularly updated since then to reflect advances in understanding and technology.

The primary purpose of IEC 60479 is to establish guidelines for assessing and preventing the harmful effects of electric currents on living organisms. The standard takes into account both direct and indirect contact with electrical systems and provides valuable insights into mitigating potential risks.

Key Principles and Provisions

IEC 60479 focuses on several key principles to ensure electrical safety. One of the fundamental concepts is determining the threshold of perception, which refers to the minimum current required to sense an electric shock. This threshold varies depending on factors such as frequency, duration, and the location of contact.

The standard also addresses the issue of body impedance, which indicates the resistance of the human body to the flow of electric current. By considering body impedance, engineers and safety professionals can design electrical systems with appropriate protection measures, minimizing the risk of injury or harm.

Application and Compliance

IEC 60479 is applicable to various industries and settings where electrical hazards are present. It provides essential guidance for professionals working with high-voltage equipment, power distribution systems, and other electrical installations.

Compliance with IEC 60479 is crucial to ensure personnel safety and regulatory adherence. Organizations are encouraged to adopt and implement the standard's provisions in their electrical safety programs, conducting risk assessments, and establishing appropriate protective measures.

Overall, IEC 60479 plays an integral role in safeguarding individuals from electric shock and other potential electrical hazards. By providing guidelines for identifying and mitigating these risks, the standard contributes to creating a safer environment for both professionals and the general public.
