What IP rating is 100% waterproof?

When it comes to electronics and outdoor gadgets, one of the most important factors to consider is their waterproof capabilities. Whether it's a smartphone, a smartwatch, or even a Bluetooth speaker, having a device that can withstand water exposure is crucial. This is where the IP rating system comes into play. In this article, we will explore what IP rating is and which IP rating guarantees 100% waterproofness.

Understanding the IP Rating System

The IP rating, short for Ingress Protection rating, is a standard used to classify the level of protection provided by electronic devices against solids and liquids. The rating consists of two digits, with each digit representing a different form of protection.

The first digit indicates the degree of protection against solid objects, such as dust and debris. It ranges from 0 to 6, with 0 providing no protection and 6 offering complete protection against dust.

The second digit represents the resistance to liquids, water being the most common concern in terms of waterproofness. It ranges from 0 to 9, with 0 meaning no protection and 9 signifying full protection against prolonged immersion in water.

The Highest IP Rating for Waterproof Devices

While many people assume that an IP68 rating guarantees 100% waterproofness, it is not entirely accurate. An IP68 rating certifies the device's ability to withstand continuous submersion in water under specific conditions, but it does not imply the device is 100% impervious to water damage.

If you are looking for a device that is truly 100% waterproof, you need to look for the highest possible IP rating, which is IPX8. The "X" in the rating signifies that the device has not been tested or certified for protection against solid objects (dust, debris, etc.), but it assures full protection against water immersion.

Devices with an IPX8 rating can be submerged in water, such as a swimming pool or the ocean, without experiencing any water damage. They will remain fully functional even when submerged at specific depths and durations mentioned by the manufacturer.


In conclusion, when it comes to finding a device that is 100% waterproof, it is essential to understand the IP rating system. While an IP68 rating offers excellent water resistance, it does not guarantee complete waterproofness. For devices that need to withstand submersion in water, an IPX8 rating is the highest standard you should look for. So, if you're planning on taking your electronic gadgets on your next swimming adventure, be sure to check for that IPX8 certification!
