BS EN 60990:2016 defines measurement methods ford.c. or a.c. current of sinusoidal or non-sinusoidal waveform, which could flow through the human body, andcurrent flowing through a protective conductor.The measuring methods recommended for TOUCH CURRENT are based upon the possible effects of current flowing through a human body. In this standard, measurements of current through networks representing the impedance of the human body are referred to as measurements of TOUCH CURRENT. These networks are not necessarily valid for the bodies of animals.The specification or implication of specific limit values is not within the scope of this standard. IEC TS 60479 series provides information regarding the effects of current passing through the human body from which limit values may be derived.This standard is applicable to all classes of EQUIPMENT, according to IEC 61140.The methods of measurement in this standard are not intended to be used forTOUCH CURRENTS having less than 1 s duration,patient currents as defined in IEC 60601-1,a.c. at frequencies below 15 Hz, andcurrents above those chosen for ELECTRIC BURN limits.This basic safety publication is 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. It is not intended for use by manufacturers or certification bodies independent of product standards.One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications. The requirements, test methods or test conditions of this basic safety publication only apply when specifically referred to or included in the relevant publications.Cross References:IEC TS 60479-1:2005IEC TS 60479-2:2007IEC 61140ISO/IEC Guide 51:2014IEC Guide 104:2010IEC 60050-195:1998IEC 60050-604:1987IEC 60065IEC 60309-1:1999IEC 60335-1IEC 60364-1IEC 60364-4-41:2005IEC TS 60479IEC 60601-1IEC 60950-1IEC 61010-1IEC 62368-1ISO/IEC Guide 50All current amendments available at time of purchase are included with the purchase of this document.
