Is IP67 OK for swimming?

In recent years, waterproof technology has become a key feature in electronic devices, making it possible to use them in various environments, including water. One commonly seen waterproof rating is IP67, but is it really safe to take your IP67-certified device swimming? Let's delve into the technical aspects of IP67 and its suitability for swimming.

Understanding IP67 Certification

IP ratings, also known as ingress protection or international protection ratings, are standardized codes used to define the level of sealing effectiveness of electrical enclosures against intrusion from foreign objects or moisture. The IP67 rating signifies that a device is completely protected from dust and can be immersed in water up to a depth of 1 meter for up to 30 minutes without any harmful effects.

Water Resistance vs. Waterproofing

It is important to differentiate between water-resistant and waterproof when considering using a device in water. Water resistance refers to the ability of a device to withstand minimal exposure to water, such as rain or accidental splashes. Waterproofing, on the other hand, implies complete protection against water immersion. While an IP67 device may seem suitable for swimming according to its rating, there are a few factors to consider.

Limits of IP67 for Swimming

Firstly, the IP67 rating is tested under laboratory conditions with static, non-turbulent water. Real-world scenarios like swimming involve dynamic movements and turbulent water, which could potentially exert greater pressure on the device than what it is rated for. Additionally, IP67 does not account for repeated use in water, such as daily swimming sessions or continuous exposure to chlorinated water, which may gradually wear down the seals. These factors can compromise the device's waterproofing over time.

Secondly, IP67 certification does not cover the functionality of touchscreens or other input methods while submerged. While some devices may still be usable underwater, others may experience reduced sensitivity or malfunction due to the pressure and conductivity of water affecting the device's interface.

In conclusion, while an IP67-rated device may provide a certain level of protection against water immersion, caution should still be exercised when using it for swimming. Factors such as dynamic movements, exposure to chlorinated water, and potential interface issues need to be considered. It is advisable to follow the manufacturer's guidelines and limitations to ensure the longevity and proper functioning of your device when exposed to water.
