Rain Test Chamber Vertical Drip Rain Tester

SPECIFICATION

Vertical Drip Rain Tester (IPX1/IPX2)

1. Test Standards

- 

IPX1 (vertical drip)

◦ 

Requirement: Vertical drip (1±0.5 mm/min) for 10 minutes with no water penetration on the sample surface.

◦ 

Scenario: simulate natural rainfall or condensation environment (e.g. indoor equipment moisture test).

- 

IPX2 (water dripping at an angle of 15°)

◦ 

Requirement: Vertical water drip (3±0.5 mm/min) when the sample is tilted at 15° for 10 minutes with no water penetration.

◦ 

Scenario: simulate the anti-drip capability of a device in a slightly tilted state (e.g., in-vehicle electronics).

Equipment core design

1. Drip system

- 

Drip tray design:

◦ 

Adopt porous metal disk or needle nozzle with uniformly distributed holes (e.g., 0.4mm) to ensure water drops fall vertically and freely.

◦ 

Drip area covers the maximum projected area of the sample to avoid edge leakage.

- 

Flow control:

◦ 

Drip rate is regulated by a precision flow meter and valve (IPX1: 1 mm/min, IPX2: 3 mm/min).

◦ 

Water tank capacity to meet continuous testing requirements (e.g. 10L or more).

2. Sample stage and tilting mechanism

- 

IPX1 mode: the sample stage remains horizontal and drips vertically.

- 

IPX2 mode: Motorized or manual tilt stage (0°-15° adjustable) to simulate a tilted state.

3. Material and Structure

- 

Box material: stainless steel or anti-corrosion coating to prevent long-term water corrosion.

- 

Transparent observation window: tempered glass or acrylic, easy to monitor the test process in real time.

- 

Drainage system: bottom deflector + water collection tank, rapid drainage and recycling.

4. Control system

- 

Automatic operation: touch screen to set drip time, flow rate, tilt angle.

- 

Alarm function: water shortage automatic shutdown, timeout reminder.

Rainwater Test Chamber (Extended Function)

For compatibility with higher waterproof rating (e.g. IPX3/IPX4), a multi-functional rainwater test box is available, integrating the following modules:

1. 

Vertical drip unit (IPX1/IPX2).

2. 

Oscillating pipe shower unit (IPX3/IPX4).

3. 

High-pressure water spray unit (IPX5/IPX6).

Selection of key parameters

Parameter

Description

Test rating

Support IPX1, IPX2, or extended to IPX3-IPX6.

Drip area

Selected according to sample size (e.g. 300 x 300mm to 1000 x 1000mm).

Flow rate accuracy

IPX1: 1±0.5 mm/min, IPX2: 3±0.5 mm/min.

Tilt mechanism

Motorized adjustment (accuracy ±1°) is superior to manual adjustment.

Standard Conformity

Conforms to IEC 60529, GB 4208, ISO 20653, etc.

Fields of application

- 

Consumer electronics: cell phones, headphones, smart watches moisture test.

- 

Automotive parts: Drip-proof verification of instrument panel, car display.

- 

Industrial equipment: sealing test for control cabinets, outdoor enclosures.

Example of operation process

1. 

IPX1 test:

◦ 

The sample is placed horizontally and a vertical drip is initiated for 10 minutes.

◦ 

Check for internal water ingress after testing.

2. 

IPX2 test:

◦ 

Tilt the sample stage to 15° to initiate dripping for 10 minutes.

◦ 

Disassemble the sample to assess sealing performance.

Maintenance and Calibration

1. 

Routine maintenance:

◦ 

Clean the drip tray to prevent scale from clogging the aperture.

◦ 

Check lubrication of tilt mechanism.

2. 

Calibration requirements:

◦ 

Calibrate drip flow rate monthly (use measuring cup to measure 1 minute of water).

◦ 

Periodically check tilt angle sensor accuracy.
