Basic test methods for ETL certification
1) leakage current test: the sample used for leakage current test has not been tested before
2) normal temperature rise: test test method: thermocouple: thermocouple of 24-30awg is required by the standard (30AWG currently used in the laboratory)
3) post-tidal leakage current test: general test conditions: T=32+/-2°C,RH=88±2%
4) voltage withstand test: normally products without double insulation and grounding are required: 1000V/1 minute (the equipment target voltage climbing time is set to 5 seconds, the cut-off current is set to 8.3ma, and then it is maintained at the target voltage for 1 minute)
