Ipx34 Water Rain Spray Test Chamber

SPECIFICATION

Test standards for IPX3 and IPX4

IPX3 (protection against drenching)

Test Requirements:

Water shower (e.g. pendulum pipe or handheld nozzle) from a range of 60° from vertical for a minimum of 5 minutes with a water volume of 10 L/min.

Application Scenario: Simulation of moderate rain or spraying environment.

IPX4 (splash-proof)

Test Requirement:

Water splashing onto the surface of the device from all directions (e.g. 360° pendulum tube) with a volume of 10 L/min for at least 10 minutes.

Application Scenario: Simulate heavy rain or multi-directional splashing environment.

Design features of the IPX34 tester

Multi-functional sprinkler system

Pendulum design:

IPX3 mode: Pendulum angle is 60°, simulating vertical direction spraying.

IPX4 mode: Pendulum angle extended to 180° or 360° to cover multi-directional splashing.

Nozzle Configuration:

Standard orifice nozzles are used (e.g. 0.4mm orifice for IPX3, 0.5mm orifice for IPX4) to ensure that water velocity and coverage are in line with standards.

Control System.

Switchable between IPX3 and IPX4 test modes, automatically adjusts pendulum angle, spray time and water flow rate.

Equipped with flow meter, pressure gauge and timer to ensure precise control of parameters (e.g. flow rate 10 L/min ±5%).

Structural design

Material: stainless steel or anti-corrosion material, resistant to long-term water corrosion.

Observation Window: Transparent tempered glass for real-time monitoring of the test process.

Sample stage: rotatable or fixed installation, adaptable to different sizes of test samples.

Water Circulation System

Built-in water tank and filtration device to recycle test water and save resources.

Equipped with drainage system to prevent water accumulation in the test chamber.

Example of test flow

IPX3 mode:

The sample is fixed in the test chamber and the pendulum is adjusted to 60°.

Spray the sample at a flow rate of 10 L/min for 5 minutes.

IPX4 mode:

The pendulum is adjusted to 180° or 360° to cover the omnidirectional sputtering.

Spray the sample at the same flow rate for 10 minutes.

Selection Key Parameters

Compatibility: Supports IPX3, IPX4 and higher ratings (e.g. IPX5/IPX6) with extended functionality.

Shower range: Pendulum radius (e.g. R200mm, R400mm) needs to match the sample size.

Degree of automation: whether to support PLC programming control, a key to switch the test mode.

Standards compliance: Compliance with international standards such as IEC 60529 and ISO 20653.

Application Fields

Consumer electronics: smart phones, smart watches, Bluetooth headphones.

Automotive industry: car camera, charging interface, car lights.

Industrial equipment: outdoor lamps, security monitoring equipment, power cabinets.

Precautions

Calibration Requirements: Regularly calibrate the nozzle flow rate and pendulum angle to ensure test accuracy.

Sample fixation: need to avoid blocking the spray path and ensure that the water covers all surfaces.

Post-test inspection: Immediately test the sample for functionality and sealing (e.g. disassemble to check for internal water ingress).
