Can IP68 be used in rain?

The IP68 rating is widely known in the tech-savvy world as a mark of protection against dust and water. It is often found on electronic devices such as smartphones, tablets, and smartwatches, claiming to be waterproof and suitable for use in various environments. However, can we really trust this rating when it comes to using these devices in the rain? In this article, we will take an in-depth look at the IP68 rating and its capabilities in rainy conditions.

Understanding the IP68 rating

To understand whether a device with an IP68 rating can be used in the rain, let's first explore what the rating actually means. The IP (Ingress Protection) rating is a standard defined by the International Electrotechnical Commission (IEC) that indicates the level of protection provided by an enclosure against the intrusion of foreign objects and moisture. The number following "IP" represents the device's protection against solid particles, while the second digit represents its protection against liquids.

The meaning behind IP6x for solids

When it comes to solids, the "6" in IP68 rating indicates that the device is completely protected against dust and other small solid particles. This implies that even in heavy rain, where there might be tiny dirt or dust particles mixed with water, the device should be safe from any intrusion that could potentially damage its internal components.

The effectiveness of IPx8 in wet conditions

Now, let's delve into the liquid aspect of the IP68 rating. The "8" in IP68 signifies that the device is protected against the effects of continuous immersion in water beyond 1 meter. This sounds promising for rain because raindrops are generally smaller and don't typically come with a lot of force compared to submerging a device underwater. However, it's important to note that the IP68 rating does not guarantee protection against pressure or water jets. Therefore, heavy rain showers or exposing the device to high-pressure water streams may pose a risk.

Limitations and considerations

Although the IP68 rating offers a considerable level of protection against dust and water, it is crucial to understand its limitations. The rating is typically tested in controlled laboratory conditions, where factors like water temperature, water flow velocity, and other environmental variables can be carefully regulated. Real-world scenarios, such as unpredictable rain patterns, temperature fluctuations, and accidental physical impacts, can significantly affect the device's performance in wet conditions. It is advised to use protective cases or covers specifically designed for rainy conditions to further safeguard your devices.

In conclusion, while devices with an IP68 rating are generally considered safe for use in rainy conditions, it is important to exercise caution and consider the limitations of this rating. Always refer to the manufacturer's guidelines and take additional protective measures to ensure the longevity and performance of your electronic devices under wet circumstances.
