Waterproof testing is essential for ensuring the reliability and durability of electrical and electronic products exposed to rain, splashes, or harsh outdoor environments. Among the most common tests are IPX3 and IPX4, defined by IEC 60529, which simulate different rainfall angles and intensities. Using precise IPX3 IPX4 test equipment, manufacturers can accurately evaluate product performance and ensure compliance with global standards.
In this article, we explore how IPX3/IPX4 test equipment works, highlight its advanced features, and explain how LIB industry provides flexible, customizable solutions for a full range of waterproof and environmental testing needs.
The IP (Ingress Protection) rating measures a product's resistance to water penetration. IPX3 and IPX4 testing ensures products remain functional under controlled water exposure:
IPX3: Simulates water sprayed at angles up to ±60° from vertical, replicating moderate rainfall conditions. Each nozzle delivers around 0.07 L/min, with test duration typically no less than 10 minutes.
IPX4: Extends the swing angle to ±180°, simulating more severe splashes from multiple directions with slightly higher flow rates.
These tests are critical for industries such as:
Consumer electronics
Household appliances
Automotive components
Outdoor lighting and communication equipment
Reliable IPX3/IPX4 testing helps manufacturers avoid product failures, recalls, and warranty claims by ensuring devices perform under realistic wet conditions.

LIB industry’s IPX3/IPX4 test equipment is engineered for precise, repeatable, and flexible waterproof testing. Its key features include:
Adjustable Oscillating Tube System: Semi-circular stainless steel tubes with φ0.4 mm nozzles (optional φ0.8 mm) spaced at 50 mm ensure uniform water coverage. Swing angles and tube radii (400mm, 600mm, or 800mm) can be tailored for IPX3 or IPX4 tests, including more severe splash conditions.
Rotating Turntable with Built-in Power: Adjustable rotation and tilt support allow uniform exposure while enabling live testing of powered electronics for real-world simulation.
Automated Water Circulation: Integrated water tank, booster pump, and filtration system provide continuous operation. Strategically located drain holes at the lowest points enable rapid water removal between tests, improving lab efficiency.
PID Programmable Controller: Touchscreen interface allows intuitive operation, real-time monitoring of water pressure and timing, and remote access via Ethernet or PC link. Supports up to 120 programs with 99 segments each and multi-language display for global use. Automatic alarms ensure safety if parameters exceed limits.
Durable Construction: The chamber and turntable are made of SUS304 stainless steel, resistant to corrosion, high humidity, and high-temperature spray environments. Transparent observation windows with LED lighting and wipers allow operators to monitor tests in real time.
Flexible Design Options: Open-frame (no-shell) IPX3/IPX4 setups are available for laboratories with space constraints, without compromising testing accuracy.

This combination of precision mechanics and advanced automation ensures reliable, repeatable, and standard-compliant waterproof testing for electronics, automotive parts, household appliances, and industrial equipment.
The system integrates advanced mechanical design with intelligent controls to deliver precise waterproof testing:
Oscillating Tube Spray
IPX3: ±60° swing, uniform 0.07 L/min water spray.
IPX4: ±180° swing for more severe splashes.
Water Flow and Pressure Control
Flow meters ensure correct rates (IPX3 ~1.8 L/min, IPX4 ~2.6 L/min).
Pressure sensors maintain consistent spray intensity for accurate results.
Rotating Turntable
Adjustable speed (1 r/min) ensures uniform product exposure.
Built-in power allows live testing of electronics during waterproof procedures.
Automated Water Management
Circulates water efficiently and filters impurities to prevent nozzle blockage.
Liquid level sensors and alarms prevent dry running and safeguard samples.
Enhanced Observation and Control
Transparent windows with LED lighting and wipers allow real-time monitoring.
PID controller with multi-language interface, programmable sequences, and remote monitoring ensures operational flexibility.
Together, these features allow LIB industry’s equipment to meet IEC 60529, ISO 20653, GJB 150.8-86, and UL standards with high repeatability.
