Cables, connectors, and polymer components are routinely exposed to water, humidity, and harsh environmental conditions. Even brief water ingress can compromise insulation, reduce mechanical performance, or cause safety hazards. For manufacturers and R&D teams, ensuring long-term waterproof performance is essential not only for product reliability but also for compliance with international standards.
The IPX7 X8 Water Immersion Tester from LIB industry combines precision engineering, intelligent controls, and customizable capabilities. It supports both compound-level material testing and enclosure-level waterproof certification, giving engineers confidence that their products will maintain integrity during prolonged water exposure. With the added advantage of customizable water temperature control, LIB’s system goes beyond conventional immersion testers, providing more accurate simulation of real-world operational conditions.
Standard | Immersion Depth | Duration | Purpose |
IPX7 | 1 m | 30 min | Validates short-term waterproof protection for enclosures and components |
IPX8 | Customizable | Extended | Simulates deeper or prolonged submersion to test long-term waterproof performance |
Key Points:
IPX7/X8 standards measure the ability to resist water ingress under specified depths and durations.
Standard immersion testers often do not control water temperature, limiting their ability to evaluate long-term material durability.
LIB testers can customize water temperature, enabling realistic simulation of long-term thermal-water aging for polymer materials such as XLPE and HFFR.
By addressing both water exposure and temperature, LIB ensures that products are tested under conditions closely resembling real-life scenarios, which is critical for industries where failure due to moisture can have significant financial or safety consequences.

A key differentiator of LIB industry water immersion testers is their ability to perform material-level evaluation, particularly for polymer compounds.
The water immersion test in XLPE & HFFR compound based on GB/T 32129 test condition 70 Centi grade × 168 hours is designed to evaluate thermal-water aging resistance, ensuring insulation materials maintain mechanical integrity and dimensional stability after prolonged exposure.
Test Objectives:
Maintain tensile strength
Preserve elongation and flexibility
Control swelling and deformation
Prevent surface cracking
Assess overall material durability and aging resistance
Why it matters:
Temperature-controlled immersion replicates real-life aging conditions that standard IPX7/IPX8 tests cannot. By simulating a 7-day continuous immersion at 70°C, manufacturers can accurately predict material performance under prolonged water exposure, ensuring products are robust and reliable over their service life.
