Breakthrough in Dustproof Testing: Sinuo Successfully Delivers Walk-in Sand and Dust Test Chamber for Large-Scale EV and Electrical Product Validation

In response to the increasing global demand for robust dust protection testing in the electric vehicle and electronics industries, Sinuo Testing Equipment Co., Ltd. proudly announces the successful delivery of a Walk-in Sand and Dust Test Chamber tailored for large-scale components and fully compliant with IEC60068-2-68-La2, ISO20653-La2, and IEC60529.

The Walk-in Dustproof Test Chamber is engineered to simulate natural sandstorm environments to evaluate the protective performance of EV products under extreme dusty conditions. It can test:

• EV AC/DC charging stations

• Charging connectors and plugs

• Outdoor power cabinets

• Enclosure systems

• And even components used in automotive and military-grade environments

• 

What Does It Test?

This advanced test chamber is designed to simulate harsh sandstorm conditions that products may encounter in real-world scenarios. It’s engineered for evaluating:

• Enclosure protection levels (IP5X, IP6X)

• Seal integrity of electrical/electronic devices and automotive parts

• Resistance to dust penetration during transport, storage, or operation

• Product durability in high-concentration airborne dust environments

Ideal test objects include electric vehicle (EV) charging stations, lighting fixtures, control cabinets, battery enclosures, and various automotive and motorcycle components.

Technical Highlights

The chamber adopts a conical funnel design with a bottom-mounted dust collection port and a high-pressure turbine circulating fan. The system draws in accumulated dust and re-injects it from the top of the chamber, creating a continuous vertical dust circulation loop. This design ensures uniform dust exposure throughout the test area.

Why a Walk-In Design?

Unlike traditional bench-top models, the walk-in structure offers maximum flexibility for testing oversized and heavy equipment. The full-open front door ensures easy access for forklifts or carts, making installation and removal of samples fast and efficient.

Real-World Impact

One of our recent customers, a prominent EV charging infrastructure provider, has successfully integrated this system into their product validation workflow. By simulating realistic sandstorm conditions, they’ve significantly improved their product’s resistance to particulate ingress, helping them meet international compliance standards faster.
