IEC 60479-2 is an international standard that provides guidelines for the evaluation of electrical shock hazards. It specifically focuses on the human body's reaction to electric current passing through it. The standard defines the effects of various levels of electric current on the human body, which helps establish safety measures and protection against electrocution.
The Purpose of IEC 60479-2
The primary purpose 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. By defining permissible limits for electric current passing through the body, the standard helps in designing protective measures and promoting safe practices that minimize the risk of electrical accidents.
Key Considerations in IEC 60479-2
IEC 60479-2 takes into account factors such as the duration of exposure, frequency of the electric current, and pathway through the body. It establishes thresholds for perception, pain, muscle contraction, and ventricular fibrillation. These thresholds help determine safe limit values, ensuring that electrical equipment is designed and operated within acceptable limits to prevent harm.
Implementation of IEC 60479-2
Implementing IEC 60479-2 involves conducting risk assessments and selecting appropriate protective measures. This may include insulation of live parts, installation of residual current devices (RCDs), and proper grounding systems. Compliance with the standard not only reduces the risk of electric shock but also ensures legal compliance and promotes overall safety awareness.
