Equipment designed and developed for the test in Clause 22.5 of IEC 60335-1 standard.

22.5 Appliances intended to be connected to the supply mains by means of a plug shall be constructed so that in normal use there is no risk of electric shock from charged capacitors having a rated capacitance exceeding 0,1 μF, when the pins of the plug are touched.

Compliance is checked by the following test.

The appliance is supplied at rated voltage. Any switch is then placed in the off position and the appliance is disconnected from the supply mains at the instant of voltage peak. One second after disconnection, the voltage between the pins of the plug is measured with an instrument that does not appreciably affect the value to be measured.

The voltage shall not exceed 34 V.

It includes input impedance of 100MΩ +/- 5 MΩ in parallel with an input capacitance of 25 pF (or less).
