1) Refer to IEC 60747-5-2 for a detailed description of voltages and partial discharge tests
2) The given value is just an example based on pollution degree 2
3) According to performed stress test (85°C, 85% relative humidity, 1000 h test time & 600 V applied insulation voltage)
4) Not subject to production test - verified by design/characterization
