Unlike ordinary splash-resistance testing, this IP68 IPX8 Water Immersion Overpressure Test Device subjects products to deeper immersion and higher water pressure. It helps manufacturers identify potential problems such as seal failures, housing deformation, connector leakage, and internal water ingress before products reach the market, reducing the risk of waterproofing failures during real-world use.
Key Features of the IP68 IPX8 Water Immersion Overpressure Test Device
1. Deep Immersion and Overpressure Testing: The device supports water pressure equivalent to approximately 50 m depth, corresponding to about 0.49 MPa of hydrostatic pressure under ideal static-water conditions. This provides a controlled environment for IPX8 and customer-specific deep-immersion testing.
2. Heavy-Duty 15 mm A3 Steel Construction: The reinforced 15 mm A3 steel chamber is designed for demanding pressure conditions. Its rigid structure minimizes deformation and provides long-term durability for repeated immersion testing.
3. Double-Layer Silicone Sealing: A two-layer silicone gasket improves contact between the lid and chamber body. The flexible sealing layer accommodates minor surface irregularities, while the supporting layer maintains sealing stability during pressure changes.
4. Adjustable 50 kg Sample Holder: The sample fixture can accommodate products weighing up to 50 kg and allows flexible positioning inside the chamber. This helps keep samples fully submerged and correctly positioned during testing.
5. Automatic Water Management and Intelligent Control: The integrated storage tank and automatic water supply system reduce manual preparation. The programmable touchscreen controller supports repeatable test settings for pressure, immersion duration, and test cycles.
6. Comprehensive Safety Protection: A water-level gauge, leak detection, overpressure relief valve, safety interlock, and floor-anchorable feet work together to improve operational safety during high-pressure immersion tests.

Applications and Applicable Standards
The IP68 IPX8 Water Immersion Overpressure Test Device can be used across automotive electronics, EV components, battery systems, outdoor electronics, LED lighting, connectors, sensors, consumer electronics, communication equipment, industrial controls, and electrical enclosures. It supports testing related to IEC 60529 for IP protection. Typical IPX7 testing uses immersion at 1 m water depth for 30 minutes, while IPX8 uses immersion conditions more severe than IPX7, with the exact depth, pressure, and duration normally specified by the manufacturer or test agreement. LIB's R78-600 can provide conditions equivalent to approximately 50 m depth / 0.5 MPa, making it suitable for customized IPX8 and IP68 qualification programs. For automotive components, ISO 20653 covers road-vehicle degrees of protection against water and foreign objects, including immersion-related IP testing. ISO 16750-4 can be used for environmental testing of road-vehicle electrical and electronic equipment, including water and temperature-related environmental stresses. IEC 60068-2-18 provides water-related environmental test methods, while GB/T 4208 provides the Chinese IP protection framework corresponding closely to IEC 60529. Typical values may include 1 m / 30 min for IPX7, approximately 0.5 MPa for 50 m equivalent deep immersion, or customer-defined conditions such as 2–10 m immersion for 30–60 minutes. Testing may evaluate water ingress, insulation performance, electrical functionality, corrosion, sealing integrity, and post-test damage.

FAQs on the IP68 IPX8 Water Immersion Overpressure Test Device
Q1: Is IPX8 always tested at 50 m depth?
No. IEC 60529 does not prescribe one universal IPX8 depth. The manufacturer and testing organization define the specific immersion depth, pressure, and duration. LIB can customize the equipment for different IPX8 requirements, including conditions equivalent to approximately 50 m depth.
Q2: Can the device perform IPX7 testing?
Yes. The chamber can reproduce the standard IPX7 condition of approximately 1 m immersion for 30 minutes, as well as more demanding customized immersion tests.
Q3: Can the sample holder be customized?
Yes. LIB can customize fixture dimensions, loading capacity, positioning methods, electrical feedthroughs, test ports, and control programs according to the product and testing procedure.
Q4: What happens after water enters the sample?
After testing, the sample can be inspected for visible water ingress, functional failure, insulation deterioration, corrosion, or internal moisture according to the applicable product standard or customer acceptance criteria.
