BS EN 61140 discusses protection against electric shock. BS EN 61140 is a basic safety publication primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51.
BS EN 61140 applies to the protection of persons and livestock against electric shock. The intent is to give fundamental principles and requirements which are common to electrical installations, systems, and equipment or necessary for their coordination, without limitations regarding the magnitude of the voltage or current, or the type of current, and for frequencies up to 1 000 Hz.
BS EN 61140 on protection against electric shock is useful for:
Electric shock is defined as the physiological effect resulting from an electric current passing through a human body or livestock. The physiological effect might be harmful (such as ventricular fibrillation, burns, asphyxiation), or non-harmful (such as muscular reaction, perception).
BS EN 61140 provides you guidance with the fundamental rule of protection against electric shock and protective provisions. BS EN 61140 guides you with the protective measures and helps you with the coordination between electrical equipment and protective provisions within an electrical installation. BS EN 61140 also guides you with special operating and servicing conditions. BS EN 61140 helps you to protect your customer against electric shocks.
