According to medical IEC6060 1- 1, what should the test high voltage be?

Different electrical appliances have different test power supply voltages and different insulation grades. In the absence of special requirements, the withstand voltage of electrical appliances will not exceed 3 to 5 times of the working voltage, that is, only low voltage can be used to measure the insulation of low-voltage lines. For example, for a 220V line, only a 500V shaking table can be used to measure insulation. If measured with a 2500V shaking table, it may break through the line insulation and damage the line.
