IEC60990 Figure 5 Measuring Network, Touch Current Weighted for Letgo-immobilization​


IEC 60990:2016 defines measurement methods for d.c. or a.c. current of sinusoidal or non-sinusoidal waveform, which could flow through the human body, and current 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 for TOUCH CURRENTS having less than 1 s duration, patient currents as defined in IEC 60601-1, a.c. at frequencies below 15 Hz, and currents above those chosen for ELECTRIC BURN limits.

Products Introduction:

This test network conforms to the measuring network requirements of IEC60990 touch current and the measurement method of protective conductor current, (figure 5-mesuring network, touch current weighted for let-go. This network is convenient to use and easy to operate, and the power supply switch is made separately, which can solve the shortcomings of power supply capacity of the previous machine and can test the more powerful products.
