Is IP68 OK for swimming?

When it comes to smartphones and other electronic devices, one of the most common questions is whether they can be safely used while swimming. This article aims to provide an in-depth analysis of the IP68 rating, which is often advertised as water-resistant and dustproof, to determine if it is truly suitable for swimming.

Understanding the IP68 Rating

The IP (Ingress Protection) rating is a standard used to classify the level of protection offered by a device against solids and liquids. The first digit represents protection against solid objects, while the second digit indicates protection against liquids. In the case of IP68, the "6" signifies that the device is dust-tight, while the "8" suggests it can be submerged in water beyond 1 meter for an extended period without damage.

Water Resistance vs. Waterproof

It's important to understand the difference between water resistance and waterproof. While a device with an IP68 rating is considered water-resistant, it does not imply absolute protection against water intrusion. This rating only guarantees protection against immersion in water under specific laboratory conditions. Factors like water depth, pressure, and duration can still impact the device's performance.

Potential Risks of Using IP68-Rated Devices for Swimming

While IP68-rated devices may withstand submersion under controlled conditions, there are several potential risks when using them for swimming:

Temperature Variations: Sudden temperature changes during swimming, such as moving from cold water to hot sunlight, can cause condensation inside the device, potentially leading to malfunctions.

Chlorine and Saltwater Corrosion: Chemicals present in swimming pools or saltwater can corrode the device over time, compromising its longevity.

Impact and Pressure: Activities like diving or water sports could subject the device to high pressure that exceeds its IP68 rating, resulting in water penetration.

In conclusion, while devices with an IP68 rating offer a significant level of protection against water and dust, it is important to exercise caution when using them for swimming. Factors such as temperature changes, exposure to chemicals, and increased pressure can still pose risks to the device's functionality. Therefore, it is advisable to follow the manufacturer's guidelines and consider additional protective measures if you plan on using your device extensively while swimming.
