Additionally, the paper presents relevant data and findings on the effectiveness and precision of these tests for evaluating water resistance at different IP ratings.

Introduction
Water resistance is a fundamental property for many products, especially those exposed to environmental elements such as rain, moisture, or water splashes. The International Protection (IP) rating system, developed by the International Electrotechnical Commission (IEC), classifies products based on their resistance to dust and water ingress. Among these ratings, IPX4 is of significant interest for electronic and electrical products that are likely to face exposure to water splashes from all directions.

The LISUN JL-X IPX4 Waterproof Test Equipment is designed to provide precise and repeatable testing for IPX4-rated products, ensuring that they can withstand water splashes without damage. The equipment features a unique swinging pipe mechanism, with adjustable angles to simulate water exposure from different directions, making it a versatile tool for compliance testing.

This paper will delve into the technical specifications and setup of the LISUN JL-X IPX4 Waterproof Test Equipment, highlighting the adjustable swing angles, sample rotation parameters, and PLC-controlled operation, while providing relevant data and results from practical tests.

Overview of IPX4 Waterproof Testing
IPX4 is a protection rating that ensures a device or product can withstand splashing water from any direction without harmful effects. This rating is commonly used for products such as electrical appliances, outdoor equipment, and lighting fixtures, which are susceptible to environmental moisture.

According to the IEC 60529 standard, the test involves spraying water from a nozzle onto the device at a specified flow rate, with a set duration and pressure. The test equipment is designed to simulate real-world conditions by adjusting the angle and position of the water spray, as well as the movement of the sample during testing.

The LISUN JL-X IPX4 Waterproof Test Equipment is specifically designed to conduct these tests with high accuracy, providing reliable results for manufacturers and regulatory bodies to ensure that their products meet the required waterproof standards.

Technical Specifications of LISUN JL-X IPX4 Waterproof Test Equipment
The LISUN JL-X IPX4 Waterproof Test Equipment is equipped with a variety of features to meet the IPX4 testing requirements. Below are the key specifications:

Parameter	Value

Swing Angle for IPX3	120° (adjustable)
Swing Angle for IPX4	180° (adjustable)
Sample Turntable Diameter	600 mm (customizable for different pipes)
Rotational Speed of Sample Turntable	1–5 rpm (controlled by PLC)
Control System	PLC-based control for precise adjustments
Spray Flow Rate	10–100 L/h (adjustable based on testing needs)
Water Pressure	80–100 kPa (adjustable)

Detailed Setup of the IPX4 Test Chamber
The LISUN JL-X IPX4 Waterproof Test Equipment employs a swinging pipe system that mimics the action of water splashing from various directions. The adjustable angles of the pipe (120° for IPX3 and 180° for IPX4) allow for a range of testing conditions to evaluate the water resistance of products. The swing pipe diameter is set to 15mm, ensuring a consistent water flow during the test.

The sample turntable has a standard diameter of 600mm, which is ideal for many products. However, depending on the type of swing pipe used, a custom turntable size may be required. The turntable rotates at speeds ranging from 1 to 5 rpm, which can be controlled via the PLC system. This ensures that the sample is exposed to water evenly from all angles during the test.

The water spray system is designed to ensure uniform water distribution, mimicking real-world scenarios where products are exposed to rain or splashing water. The flow rate can be adjusted from 10 to 100 liters per hour, while the water pressure is typically set between 80 to 100 kPa.

PLC-Controlled Testing Process
The PLC control system is an essential feature of the LISUN JL-X IPX4 Waterproof Test Equipment, offering precise control over various parameters such as the swing pipe angle, sample rotation speed, and water flow rate. The system ensures that the test is repeatable and can be adjusted for different testing scenarios.
1. Adjusting Swing Pipe Angles: The PLC allows the user to adjust the swing pipe angle to 120° for IPX3 or 180° for IPX4 testing. The angle can be fine-tuned to simulate water exposure from different directions, providing flexibility in testing.
2. Controlling Sample Rotation: The sample turntable’s rotational speed can be adjusted from 1 to 5 rpm via the PLC system. This ensures that the product is exposed to water in a controlled manner, simulating real-world conditions.
3. Water Flow and Pressure Settings: The PLC system also allows the operator to set the desired water flow rate and pressure. This capability is crucial for ensuring that the test conditions align with the standards outlined in IEC 60529 for IPX4 waterproof testing.

Testing Procedure
The test procedure for IPX4 waterproof testing typically follows these steps:
1. Preparation of Sample: The sample to be tested is placed on the turntable, ensuring that it is securely positioned for rotation.
2. Setup of Swing Pipe: The swing pipe is positioned at the desired angle (120° for IPX3 or 180° for IPX4), and the water flow rate is set according to the testing requirements.
3. Activation of Test: Once the setup is complete, the PLC system is used to initiate the test. The sample turntable rotates at the specified speed, while the water is sprayed from the swing pipe at the target product.
4. Observation and Evaluation: The product is examined after the test for any signs of water ingress or damage. The test duration typically lasts for 10 to 15 minutes, depending on the standards being followed.
5. Reporting: The test results are recorded, including any issues such as water penetration, and are used for compliance verification.
