12. Verification of IC-CPD Performance During Power Voltage Loss: Ensures the charger remains safe during sudden power voltage loss.

13. Verification of Non-Operating Current Limits Under Overcurrent Conditions: Tests the charger’s current limiting performance under overcurrent conditions.

14. Resistance to Unnecessary Tripping Due to Surge Currents Caused by Impulse Voltage Verification: Ensures the charger does not trip unnecessarily during surge conditions.

15. Reliability Verification: Confirms the charger’s reliability under various usage conditions through long-term testing.

16. Aging Resistance Test: Evaluates the aging characteristics of materials and components over prolonged use.

17. Tracking Resistance Test: Tests the electrical insulation performance of the charger’s materials in humid environments.

18. Test on Pins Equipped with Insulating Sleeves: Ensures the insulating sleeves on the charger’s pins do not fail during use.

19. Mechanical Strength Test of Non-Solid Pins on Plugs: Tests the mechanical strength of non-solid pins on the charger’s plug to ensure durability during insertion and removal.

20. Verification of Strain Effects on Conductors: Assesses the stability of the charger’s conductors under mechanical stress.

21. Torque Application to Fixed Sockets Verification: Ensures the charger’s stability when plugged into fixed sockets.

22. Cord Anchorage Test: Tests the strength of the charger’s cable anchorage to ensure it does not fail under tension.

23. Flexing Test for Non-Detachable IC-CPD: Evaluates the charger's flexural performance under repeated bending conditions.

24. Electromagnetic Compatibility (EMC) Verification: Tests the charger’s compatibility in electromagnetic environments to ensure it does not emit or receive harmful interference.

25. Verification of Clearance and Creepage Distances: Evaluates the electrical safety by verifying the clearance and creepage distances.

26. Verification of Individual Electronic Components in IC-CPD: Confirms the performance and reliability of all electronic components used in the charger.

27. Chemical Load Test: Tests the charger’s resistance to chemical substances.

28. Thermal Test Under Solar Radiation: Evaluates the charger’s performance under direct sunlight exposure.

29. UV Radiation Resistance Test: Tests the material durability of the charger under UV radiation.

30. Damp Heat and Salt Spray Test for Marine and Coastal Environments: Assesses the charger’s corrosion resistance in humid and salty conditions.

31. Damp Heat Test for Tropical Environments: Tests the charger’s performance in high-temperature, high-humidity environments.

32. Vehicle Drive-Over and Related Tests: Evaluates the charger’s durability under extreme mechanical pressure. 

By passing these comprehensive tests and validations, portable chargers that comply with the IEC 62752 standard are ensured to meet high standards of safety, durability, and reliability, thus satisfying consumer needs.
