IEC 62196-3 Overpressure Test System | 1.0–10.0 Bar EV Liquid Cooling Leakage Tester

This overpressure test system fully complies with the test requirements specified in Clause AA.38.6 of IEC 62196-3:2026 and Clause 101.6 of IEC 62196-3-1:2022. It is designed to conduct pressure leakage tests to verify the sealing performance of liquid cooling components with a volume below 10 liters.

Equipped with a booster pump, the system can output adjustable high pressure to validate the pressure withstand capability of test samples against different rated pressure specifications. The complete unit consists of an electrical control subsystem, a precision pressure regulation subsystem and a water storage tank. Workpieces are manually mounted and plumbed for testing.

This over-pressure test system is developed strictly in accordance with IEC 62196-3:2026 Clause AA.38.6 and IEC 62196-3-1:2022 Clause 101.6, and its application scope is sorted into 3 clear parts as below:

• Manufacturers of liquid-cooled DC charging guns and cooling assemblies

• Independent third-party certification laboratories for EV charging products

• Internal quality control & inspection workshops of charging equipment factories

• R&D type testing for new liquid cooling components

• Routine factory outgoing inspection before product shipment

• Formal testing data support for global IEC product certification

• Conduct standardized pressure leakage & pressure withstand tests to check sealing safety

• Record full-process pressure curves and automatically export traceable Excel test reports

• Generate IEC-standard-compliant test data to help products pass international EV charging equipment     certification smoothly
