Built without a fully enclosed test chamber shell, LIB Industry's IPX3 Spraying Water and IPX4 Splashing Water Test Equipment offers a lighter, more mobile footprint that can be reconfigured quickly between test setups. The stainless-steel drip tray and water tank resist corrosion from repeated exposure, while the automatic water supply system with flowmeter-based pressure control keeps spray output consistent throughout every test cycle. A programmable color LCD touchscreen controller allows operators to store multiple test protocols, adjust oscillating angle and rotation speed, and log test duration from 0 to 99 hours 59 minutes.
Functional Advantages of the IPX3 Spraying Water and IPX4 Splashing Water Test Equipment
1. Multi-Directional Spray Coverage: The oscillating tube assembly sweeps through an adjustable arc of 0° to ±180°, while the turntable simultaneously rotates the test sample at approximately 1 r/min. This combined motion ensures water reaches every angle of the specimen, faithfully simulating IPX3's directional spray requirement and IPX4's splashing-from-all-directions requirement.
2. Precision Water Delivery System: Spray nozzles measuring 0.4 mm in diameter, spaced 50 mm apart, produce a controlled, uniform water pattern. Flow rate is monitored via a dedicated flowmeter rather than relying solely on pump pressure, allowing testers to maintain the water volume and pressure values specified in IEC 60529 and ISO 20653 throughout the full exposure duration.
3. Flexible Open-Frame Design: Because the platform is not enclosed in a fixed housing, it accommodates larger or irregularly shaped samples — such as vehicle headlamp assemblies, outdoor junction boxes, or industrial panels — that would not fit inside a conventional rain chamber. This flexibility reduces the need for multiple dedicated fixtures across different product lines.
4. Automated Water Management: An integrated water tank, booster pump, automatic replenishment system, and water purification unit maintain consistent water quality and pressure. This reduces mineral buildup on nozzles and prevents residue from affecting spray uniformity over long test campaigns.
5. User-Friendly Programmable Control: The color LCD touchscreen supports Ethernet connectivity and PC linkage, enabling remote monitoring and data logging. Operators can pre-set spray duration, oscillation range, and rotation speed for repeatable testing across shifts or between different laboratories.
6. Durable, Corrosion-Resistant Build: All wetted components, including the drip tray, turntable, and water tank, are constructed from stainless steel to resist long-term corrosion from continuous water exposure, ensuring stable performance and a long service life even under frequent daily testing.

Applications and Industries of the IPX3 Spraying Water and IPX4 Splashing Water Test Equipment
This equipment is widely used across automotive electronics (headlamps, sensors, connectors, ECUs tested per ISO 20653 with typical spray durations of 5 minutes), outdoor telecommunications and networking enclosures (IEC 60529 IPX3/IPX4 verification with water flow rates around 10 L/min for a 3-minute exposure), household and commercial appliances (washing machines, outdoor lighting, garden equipment), industrial control cabinets, marine and offshore electronics, and rail transportation components. Typical test parameters include spray angles of 60° from vertical for IPX3 and all-direction splashing for IPX4, water flow rates in the range of 10 L/min, and standard exposure times of approximately 5 minutes per specimen orientation, though exact values depend on sample size per the referencing product standard.

FAQs on the IPX3 Spraying Water and IPX4 Splashing Water Test Equipment
Q1: Can this equipment test both IPX3 and IPX4 protection levels on the same unit?
Yes. The oscillating spray tube angle and turntable rotation are both adjustable, allowing the same platform to switch between IPX3 spray configurations and IPX4 splashing configurations without requiring separate equipment.
Q2: What is the maximum sample size this equipment can accommodate?
Since the platform is open-frame rather than enclosed, sample size is primarily limited by the turntable diameter and oscillating tube radius (400–600 mm depending on model), making it more flexible for large or irregular parts than fully enclosed chambers.
Q3: How is water pressure and flow consistency maintained during long test cycles?
Water pressure is continuously monitored via a flowmeter rather than pump output alone, and the automatic water supply system replenishes the tank in real time, ensuring stable spray conditions are maintained for the full programmed test duration.
