Waterproof Ratings in Electronic Devices: Can IP68 be used in rain?

The IP (Ingress Protection) rating is a classification system that determines the degree of protection provided by an electronic device against both solid objects and water. With increasing demand for waterproof devices, the IP68 rating is gaining popularity. But can it truly withstand rain? Let's delve into the technical details to find out.

Understanding the IP Rating System

The IP rating system consists of two digits. The first digit represents the level of protection against solid objects like dust, while the second digit indicates water resistance. An IP68 rating means the device is protected against dust (6) and can withstand continuous immersion in water beyond 1 meter (8). However, it's important to note that it doesn't guarantee complete protection against all types of moisture, including rain.

The Truth about IP68 and Rain

While IP68-rated devices offer excellent protection against accidental water splashes and even brief submersion, they may not fare as well when exposed to heavy rain. Rainfall involves various factors, such as droplet size, duration, and pressure. These factors can challenge the sealing capabilities of an electronic device, even if it has a high IP rating.

Rainwater, especially when it falls in the form of heavy showers or during storms, can exert significant pressure on the device's seals and openings. Despite the IP68 rating, there is still a possibility of moisture seeping into the device, potentially causing damage to sensitive internal components.

Taking Precautions

If you plan on using an IP68-rated device in the rain, it's essential to take certain precautions. Firstly, avoid unnecessary exposure to heavy rain whenever possible. Secondly, ensure that all ports and openings are securely closed before entering a rainy environment. Additionally, consider using protective cases specifically designed to offer extra water resistance.

It's worth noting that manufacturers provide IP ratings as guidelines and do not guarantee full protection in all scenarios. Rainfall conditions can vary greatly, and even the highest IP-rated devices have limits to their waterproof capabilities.

In Conclusion

The IP68 rating provides a high level of waterproofing and dust resistance for electronic devices. While it offers suitable protection in most situations, it may not be entirely reliable during heavy rainfall. To ensure the longevity of your device, it's advisable to take precautions and minimize its exposure to excessive rain whenever possible.

Remember, while an IP68 device can handle accidental submersion or splashes, it's always better to err on the side of caution when it comes to heavy rain.
