Introduction to Immersion Tank Waterproof Testing

Waterproof testing is a critical validation step for products exposed to moisture, humidity, or direct liquid contact. Immersion tank testing, a subset of ingress protection (IP) testing, evaluates a device’s ability to withstand prolonged or temporary submersion in water without functional degradation. This method is governed by international standards such as IEC 60529, ISO 20653, and MIL-STD-810, which define test conditions, durations, and performance criteria.

Le LISUN JL-XC Series immersion tank waterproof test device is engineered to meet rigorous industry demands, offering precise control over test parameters, including submersion depth, duration, and water temperature. Its modular design accommodates diverse product sizes, making it suitable for sectors ranging from automotive electronics to medical devices.

Technical Principles of Immersion Tank Testing

Immersion testing simulates real-world liquid exposure scenarios, including accidental submersion, high-pressure sprays, or condensation buildup. The test involves:

1. Static Immersion: The device is submerged at a specified depth for a predetermined period (e.g., 30 minutes at 1 meter per IPX7).
2. Dynamic Immersion: Products undergo cyclic immersion-emersion sequences to assess resistance to repeated water exposure.
3. Temperature-Variable Testing: Some standards require immersion in heated or chilled water to evaluate thermal shock effects.

The LISUN JL-XC Series employs a closed-loop water circulation system with adjustable flow rates and temperature stabilization (±0.5°C accuracy). Its stainless-steel construction ensures corrosion resistance, while integrated sensors monitor water purity and test conditions in real time.

Key Specifications of the LISUN JL-XC Series

Applications industrielles

1. Électronique automobile

Automotive components, such as battery management systems (BMS) and LED lighting modules, must endure road splash, humidity, and submersion in flood conditions. The JL-XC Series verifies IP67/IP68 compliance for connectors, sensors, and infotainment systems.

2. Dispositifs médicaux

Portable diagnostic equipment and surgical tools undergo immersion testing to ensure sterilization compatibility and leak-proof integrity. The JL-XC’s precision temperature control is critical for validating devices exposed to autoclaving or liquid disinfectants.

3. Équipements de télécommunications

5G enclosures and fiber-optic junction boxes are tested for waterproofing to prevent signal degradation in humid or submerged environments. Dynamic immersion cycles replicate monsoonal rainfall or tidal exposure.

4. Aerospace and Aviation

Avionics housings and satellite components are subjected to high-pressure immersion (simulating deep-sea or high-altitude condensation) using the JL-XC’s pressurized tank variant.

Competitive Advantages of the JL-XC Series

1. Adaptive Test Protocols: Pre-programmed profiles for IPX7, IPX8, and custom test sequences reduce setup time.
2. Enhanced Durability: The stainless-steel tank resists saltwater corrosion, making it suitable for marine applications.
3. Conformité réglementaire : Automated reporting aligns with IEC, ISO, and MIL-STD documentation requirements.
4. Scalability: Modular extensions allow testing of large assemblies, such as EV battery packs or industrial control cabinets.

Case Study: Waterproof Validation for EV Charging Stations

A European automotive manufacturer utilized the JL-XC Series to validate the waterproofing of a next-gen DC fast-charging connector. The test protocol included:

• 30-minute static immersion (1.5m depth, 25°C)
• Thermal cycling (-20°C to 60°C)
• Post-test dielectric strength verification

Results confirmed IP68 compliance, with zero leakage detected after 500 test cycles.

Section FAQ

Q1: What distinguishes IPX7 from IPX8 testing?
IPX7 requires 30-minute immersion at 1m depth, while IPX8 involves deeper/longer submersion per manufacturer specifications. The JL-XC Series supports both with adjustable parameters.

Q2: Can the JL-XC test pressurized enclosures?
Yes, optional pressure modules simulate deep-water conditions up to 5 bar for submarine or oil/gas applications.

Q3: How is water purity maintained during testing?
The system includes filtration and UV sterilization to prevent contaminants from affecting test results.

Q4: What industries benefit most from dynamic immersion testing?
Automotive and aerospace sectors, where components face cyclic wet/dry conditions, require dynamic validation.

Q5: Does the JL-XC support third-party calibration?
Yes, the device is designed for traceable calibration via NIST or ISO 17025-accredited labs.
