As global product safety requirements continue to evolve, testing laboratories are facing increasing demand for comprehensive and reliable IP waterproof testing services.
For laboratories serving multiple industries and international customers, having only a single waterproof test method is often not enough. Different products may require different levels of water ingress protection testing, from IPX1/IPX2 drip testing to IPX3/IPX4 spray testing, IPX5/IPX6 water jet testing, and IPX7/IPX8 immersion testing.
Recently, Sinuo's IEC 60529 Full-featured IPX1–IPX8 Integrated Waterproof Testing System has become one of our most frequently ordered waterproof testing solutions. Several internationally recognized testing laboratory groups have selected this integrated system for their laboratory testing projects.

The customers involved in these projects are professional testing laboratories providing product testing, certification, quality verification and compliance services for manufacturers in different industries.
Their testing requirements were not limited to one specific IP rating.
Depending on the product under evaluation, their laboratories may need to perform:
This created a practical challenge for laboratory planning.
Instead of purchasing and managing several completely independent waterproof testing machines, the laboratories were looking for a more comprehensive IPX1–IPX8 waterproof testing solution that could support different test methods within one coordinated laboratory system.
A conventional waterproof testing laboratory may need separate equipment for dripping, spraying, water jetting and immersion.
As testing capabilities expand, this can result in:
For a professional testing laboratory handling different products every day, these issues can directly affect workflow efficiency.
The customers therefore wanted a solution that could provide broad IPX test coverage while keeping the laboratory system organized and efficient.
Based on the laboratory's requirements, Sinuo provided the SN4418 IEC 60529 Full-featured IPX1–IPX8 Integrated Waterproof Testing System.
The system combines multiple waterproof test functions into one coordinated solution, covering IPX1 through IPX8. The current configuration includes vertical rain/drip testing, oscillating tube testing, spray nozzle testing, hose nozzle testing, IPX7 immersion and IPX8 deep immersion.
| Test Rating | Test Method | Main Equipment |
|---|---|---|
| IPX1 | Vertically falling water drops | Vertical rain/drip apparatus |
| IPX2 | Dripping with enclosure tilted | Vertical rain/drip apparatus |
| IPX3 | Spraying water | Oscillating tube / spray nozzle |
| IPX4 | Splashing water | Oscillating tube / spray nozzle |
| IPX5 | Water jet | Hose nozzle |
| IPX6 | Powerful water jet | Hose nozzle |
| IPX7 | Temporary immersion | Integrated immersion chamber |
| IPX8 | Deep/continuous immersion | Pressure-controlled immersion tank |
The integrated architecture allows the laboratory to establish a much broader water ingress protection testing capability without treating every IPX rating as an isolated testing project.
Another important feature of the solution is its centralized control architecture.
Instead of operating completely independent machines with separate control interfaces, the integrated system uses a centralized control cabinet with PLC control and a touchscreen interface.
The system is designed to coordinate functions such as:
This centralized approach can make daily operation easier for laboratory technicians, particularly when the laboratory performs different IP tests throughout the day.
From the projects we have recently supplied, one clear trend is emerging:
Professional testing laboratories increasingly need more than a single waterproof test machine. They need a complete IP testing capability.
For laboratories serving multiple customers and product categories, an integrated IPX1–IPX8 system can provide several practical advantages.
The laboratory can establish testing capabilities covering the complete range from dripping to deep immersion.
Multiple test functions can be planned as one integrated testing solution instead of purchasing unrelated equipment separately.
A centralized control architecture helps technicians manage different test functions more efficiently.
The system can be applied to a broad range of products, including:
These application areas are consistent with the product's intended use as a comprehensive IP waterproof testing solution.
The demand for comprehensive IP testing is not limited to one product category.
A single testing laboratory may serve manufacturers of household appliances in one project, lighting products in another, and automotive or EV components in the next.
This is one reason the IEC 60529 IPX1–IPX8 integrated waterproof testing system has attracted interest from professional testing laboratories.
Instead of designing the laboratory around one specific product, the system provides a broader testing platform that can support multiple product categories and future testing requirements.
With the growing adoption of the SN4418 integrated waterproof testing system, Sinuo is continuing to support laboratories and manufacturers looking to establish comprehensive IPX1–IPX8 waterproof testing capabilities.
Our experience covers not only individual IPX test equipment, but also integrated solutions combining:
IPX1/IPX2 drip → IPX3/IPX4 spray → IPX5/IPX6 water jet → IPX7 immersion → IPX8 deep immersion.
For laboratories planning a new IP testing facility, expanding existing waterproof testing capabilities, or replacing multiple standalone machines with an integrated system, Sinuo can provide technical consultation, equipment configuration and customized laboratory solutions.
