In routine testing, we often come across the term "IPX3/4 water ingress test". But do you truly understand the core equipment for such tests — the oscillating tube rain testing equipment? Today, we will explain its applications, design standards and different models in plain language.

1. What is an Oscillating Tube Rain Testing Equipment?

The oscillating tube rain testing equipment is a professional device specially designed for IPX3/4 water resistance testing. Its core function is to simulate natural rainfall and splashing environments. Through standardized water spraying, it accurately tests the water resistance of various products, verifying whether their enclosures and sealing structures can withstand light rain and water splashing. It is widely used in electronics, lighting, home appliances and other industries.

2. Design & Development Standards (Compliance Assurance)

The design and development of the equipment strictly comply with a number of standards to ensure authoritative and compliant test results:

IEC60529:1989+A1:1999+A2:2013 Degrees of protection provided by enclosures (IP Code)

IEC60598-1: 2020 Luminaires - Part 1: General Requirements and Tests

3. Three Models for Different Test Samples

Based on sample size and testing requirements, the rain testing equipment are mainly available in three versions: portable, chamber and open-frame, each with its own advantages for efficient selection.

Portable Type: For large samples, flexible and convenient

The key advantage of the portable model is flexibility. It uses a hand-held spray nozzle for water resistance testing and is specially designed for large samples.

Key features:

● Spray angle and coverage can be adjusted via baffles

● Equipped with an electronic flow meter for accurate water volume measurement

● Simple operation, easy to move, no fixed installation required

Chamber Type: For small and medium samples, precise and controllable

Adopting a fully enclosed chamber structure, it focuses on high precision and ease of use, ideal for water resistance tests on small and medium-sized samples such as electronic components and lighting fixtures.

Key features:

● Inner chamber made of 304 stainless steel, corrosion-resistant and easy to clean

● Internal water circulation for energy saving and environmental protection

● 7-inch touch screen with intuitive operation and programmable control

● Samples can be tested while powered on; rotating worktable is height-adjustable

● One-key operation system with manually adjustable water flow, user-friendly for beginners

Open-Frame Type: For large samples, complete specifications

Similar to the portable type, it is designed for large sample testing but offers more specifications and better controllability, suitable for large equipment requiring high testing accuracy.

Key features:

● A full range of oscillating tube sizes: R200, R400, R600, R800, R1000, R1200, R1400, R1600

● Programmable control, one-key operation, and manually adjustable water flow

In addition to the three standard models, customized solutions are also available to meet the personalized testing needs of different industries and various products.
