What is IEC 60479-1?

IEC 60479-1, also known as "Effects of current on human beings and livestock - Part 1: General aspects," is an international standard that provides guidelines for assessing the effects of electrical current on the human body. It was developed by the International Electrotechnical Commission (IEC), a global organization that sets standards for the electrical, electronic, and related technologies.

The Importance of IEC 60479-1

IEC 60479-1 plays a crucial role in ensuring the safety of individuals working with or around electrical equipment. By defining specific limits for electric shock, the standard helps prevent accidents, injuries, and even fatalities. It provides valuable information for designing and implementing protective measures, reducing the risks associated with electrical installations.

Key Requirements of IEC 60479-1:

The standard outlines several key requirements to ensure electrical safety. These include limits for touch voltage and step voltage, thresholds for perception of electric shock, and guidelines for assessing the effects of current on different parts of the body. It also addresses the influence of factors such as frequency, duration, and waveform of the electrical current. Compliance with these requirements ensures that electrical systems are designed and operated in a manner that minimizes the risk of harm to humans.

Application of IEC 60479-1

IEC 60479-1 is applicable to a wide range of industries and sectors, including power generation, transmission and distribution, telecommunications, manufacturing, and construction. Compliance with the standard is vital for designers, engineers, electricians, and other professionals involved in electrical installations and operations. It helps them make informed decisions about equipment selection, installation methods, grounding, and other safety measures.
