When doing safety certification, does leakage current refer to cold state current or hot state current? Thank you!

Leakage current referred to in the safety regulations is the current from the primary to the secondary or ground, usually in the warm-up state, is a relatively stable value, the limit value of 0.25mA and 3.5mA, the limit value of the reliable grounded part of the 3.5mA, the rest of the 0.25mA.

By the way, the leakage current is mainly generated by the capacitance across the (pri-sec, or pri - GND), the larger the value of such capacitance, the greater the leakage current, the theoretical capacitance limit value is 3300mA. or pri - GND), the larger the value of such capacitance, the higher the leakage current, the theoretical capacitance limit value of 3300pF. Usually exceeding this capacitance value will result in the leakage current exceeding the limit value (0.25mA/ 3.5mA)
