Defines measurement methods for d. c. or a. c. of sinusoidal or non-sinusoidal waveform, which could flow through the human body, and current which can flow through a protective conductor. Measuring methods recommended for touch-current are based upon the possible effects of current flowing through a human body. Specification or implication of specific limit values is not included. Is applicable to all classes of equipment, according to IEC 536. The methods of measurement herein are not intended to be used for touch-current having less than 1 s duration, patient currents as defined in IEC 601-1, a. c. at frequencies below 15 Hz, a. c. in combination with d. c. and currents above those chosen for electric burn limits.
