What is IEC 60479-8?

Introduction

IEC 60479-8 is an international technical standard that deals with the effects of current passing through the human body. It is part of a series of standards developed by the International Electrotechnical Commission (IEC) to ensure safety in electrical installations.

Scope and Purpose

The purpose of IEC 60479-8 is to provide guidelines for calculating the effects of electric shock on the human body. It addresses the physiological and psychological aspects of electrical currents and their potential hazards. This standard is essential for professionals working in the field of electrical engineering or involved in the design, installation, or maintenance of electrical systems.

Main Requirements

IEC 60479-8 outlines specific requirements related to assessing the effects of electric current through the human body. These include defining safe exposure limits, determining thresholds for perception and pain, and providing guidance on the calculation of tissue damage caused by electric shocks. The standard also emphasizes the importance of considering factors such as frequency, duration, waveform, and body resistance during risk assessment.

Implementation and Compliance

Compliance with IEC 60479-8 requires electrical engineers and professionals to ensure that electrical systems are designed and installed according to the standard's guidelines. It is crucial to assess the potential risks associated with electrical currents and implement appropriate protective measures to prevent electric shock accidents. Regular inspections, testing, and maintenance are also necessary to ensure ongoing compliance with the standard.
