UL 60950-1 STANDARD FOR SAFETY Information Technology Equipment Safety Part 1: General Requirements

Electric shock is due to current passing through the human body. The resuting physiological effects depend on the value and duration of the current and the path it takes through the body.
The value of the current depends on the applied voltage, the impedance of the source and the impedance of the body, The body impedance depends in turn on the area of contact, moisture in the area of contact and the applied voltage and frequency. Currents of approximately half a milliampere can cause a reaction in persons in good health and may cause injury indirectly due to involuntary reaction. Higher currents can have more direct effects, such as burm, muscle tetanization leading to inability to let go or to ventricular fibilation.
