## Article

We recently conducted a series of environmental stress tests using [WIZnet’s WIZ630io module](https://docs.wiznet.io/Product/ioModule/wiz630io) paired with a Raspberry Pi Pico. The goal was to validate the system’s reliability under extreme temperature and humidity conditions. Each test lasted 8 hours and was monitored using VisuWin and thermal chamber systems.

---

## ✅ Test Objective

The WIZ630io module is designed for industrial-grade applications. To ensure robust performance in harsh environments, we evaluated how well the module operates under **high temperature**, **low temperature**, and **high humidity** conditions over prolonged periods.

## 🔧 Test Setup

### ✅ Class A Compliance Achieved

The WIZ630io module, in combination with the Raspberry Pi Pico, **fully complies with EMI Class A standards**. This means the system is suitable for use in industrial and commercial environments where strict emission control is required. All measured emissions remained **well within the acceptable margins**, confirming the module’s robustness in terms of electromagnetic interference.

## ⚡ ESD (Electrostatic Discharge) Immunity Test

To ensure the module’s robustness against sudden electrostatic discharges—a common real-world threat—we also performed an **ESD immunity test** according to IEC 61000-4-2 standards.

**Test Voltage**: ±4kV (Contact Discharge)

**Result**: **No abnormal behavior or communication issues observed**.

**Conclusion**: The WIZ630io module **passed the ±4kV ESD test without failure**, confirming its suitability for environments where electrostatic exposure is likely (e.g., during handling, installation, or field operation).
