What is IEC 60479-2 ?

IEC 60479-2 is an essential standard for ensuring electrical safety. It provides guidelines for evaluating the hazards associated with electrical installations and minimizing the risk of electric shock to humans. The standard specifically focuses on the human body's reaction to electric current passing through it, defining the effects of various levels of electric current on the body and establishing safety measures to protect against electrocution.

One of the primary purposes of IEC 60479-2 is to assess the potential risks associated with electrical installations and ensure the safety of individuals working with or around electrical equipment. It defines permissible limits for electric current passing through the body, which helps in designing protective measures and promoting safe practices that minimize the risk of electrical accidents.

The standard takes into account various factors such as the duration of exposure, body resistance, and the current intensity. It classifies the severity of electric shocks into different zones and specifies appropriate protective measures for each zone. It also considers the effects of alternating and direct current on the human body, providing valuable insights for ensuring electrical safety across different systems.

IEC 60479-2 is applicable not only to household electrical systems but also extends to industrial plants, public spaces, and any environment where electrical installations exist. It greatly assists in the decision-making process when selecting protective measures for electrical installations, helping professionals evaluate the potential hazards associated with electrical systems and implement effective safety measures.

By adhering to the provisions outlined in this standard, electrical system designers, installers, and engineers can ensure that their installations are safe and comply with internationally recognized guidelines. The standard is an essential tool for minimizing the risk of electrical accidents, protecting both personnel and property.
