Imagine an electric vehicle driving through a flooded road after a heavy storm. Water covers the lower body, surrounds connectors, and reaches important electronic components. At the same time, outdoor lighting, smart devices, and industrial sensors may face unexpected water exposure during daily operation. Without reliable waterproof protection, even a small sealing failure can lead to electrical damage, safety risks, or product failure.

This article explains what products can be tested with an IPX7 IPX8 Water Immersion Tank, how the equipment performs waterproof testing according to IEC 60529 requirements, and how LIB IPX7 IPX8 Water Immersion Tank helps manufacturers verify product reliability under temporary and continuous water immersion conditions.

IPX7 IPX8 Water Immersion Tank Testing Standards Based on IEC 60529

IPX7 Testing Standard: Temporary Immersion at 1 Meter for 30 Minutes

The IPX7 protection level defined by IEC 60529 evaluates whether an enclosure can prevent harmful water ingress during temporary immersion. According to the standard, products must be immersed in water at a depth of 1 meter for 30 minutes. After testing, the product should continue operating normally without damage caused by water penetration.

Typical products requiring IPX7 testing include smartphones, wearable devices, vehicle sensors, connectors, portable instruments, and outdoor electronic equipment. Automotive components are also commonly evaluated according to ISO 20653, which defines protection levels for road vehicle electrical equipment.

LIB IPX7 IPX8 Water Immersion Tank simulates this condition by controlling immersion depth, testing time, and water pressure. The sealed pressure vessel creates a stable underwater environment, while sensors monitor water level and pressure in real time. The programmable controller automatically controls test cycles, ensuring repeatable and accurate results.

For reliable operation, regular maintenance is important. Operators should check sealing rings, pressure valves, water quality, and sensor calibration regularly. Cleaning the tank after testing prevents contamination and ensures stable pressure performance during long-term operation.

IPX8 Testing Standard: Continuous Immersion Under Manufacturer-Defined Conditions

Compared with IPX7, IPX8 testing focuses on continuous immersion under deeper or longer underwater conditions. According to IEC 60529, IPX8 conditions are determined by the manufacturer, but they generally exceed IPX7 requirements. Industrial testing commonly simulates water depths of 10 meters, 20 meters, or even 50 meters.

For example, a water pressure of approximately 0.5 MPa represents the hydrostatic pressure experienced at around 50 meters underwater. This allows manufacturers to evaluate products exposed to extreme flooding, underwater environments, or long-term immersion.

LIB IPX7 IPX8 Water Immersion Tank uses pressure-controlled technology instead of simply increasing water height. The system increases internal pressure to reproduce underwater pressure conditions accurately. This method provides stable simulation for products such as underwater sensors, marine electronics, EV battery components, charging connectors, and communication equipment.

The equipment supports testing requirements from standards including IEC 60529 IPX8, ISO 20653 IPX8, and GB/T 4208. For military and harsh environmental applications, related waterproof evaluations may also refer to MIL-STD-810 procedures.

Maintenance of IPX8 equipment requires special attention because of higher pressure operation. Regular inspection of the pressure vessel, automatic valves, safety locks, and pressure sensors helps maintain testing accuracy and operational safety.

IPX7 IPX8 Water Immersion Tank Working Principle and Maintenance Guide

An IPX7 IPX8 Water Immersion Tank creates controlled underwater environments to evaluate whether products can resist water penetration. During testing, the sample is placed inside the chamber, and the system adjusts water level or internal pressure according to the required IP rating.

For IPX7 testing, the chamber controls immersion depth and duration, reproducing the condition of 1-meter water immersion for 30 minutes. For IPX8 testing, the system generates higher pressure levels to simulate deeper underwater environments.

LIB immersion tanks use a programmable touchscreen controller, automatic water supply system, pressure monitoring sensors, and safety protection devices. The controller allows users to set parameters such as immersion time, pressure value, and test cycles. Real-time monitoring ensures stable testing conditions and improves repeatability.

Key maintenance recommendations include:

① Check sealing components before every test to prevent leakage.

② Clean the water tank regularly to avoid impurities affecting sensors.

③ Calibrate pressure sensors periodically to maintain accuracy.

④ Inspect pneumatic lids and safety locks for reliable operation.

⑤ Replace damaged seals or valves immediately.

With proper maintenance, LIB IPX7 IPX8 Water Immersion Tank can provide long-term stable performance for laboratories and production testing environments.
