Understanding IP Ratings: What Makes A Device Fully Waterproof?

In the realm of electronics and technology, the term "waterproof" is frequently used to describe devices capable of withstanding exposure to water. However, not all devices labeled as waterproof offer the same level of protection. The degree of water resistance is determined by the device's Ingress Protection (IP) rating, which is a standardized system that classifies the level of protection against solid particles and liquids.

IP ratings are composed of two digits, each representing a specific level of protection against solids and liquids. For example, an IP67 rating indicates that the "6" offers protection against solid particles such as dust, while the "7" signifies that the device can be submerged in water up to 1 meter for up to 30 minutes. But which IP rating is considered to be fully waterproof?

A device is typically considered fully waterproof if it has an IP68 rating. Let's delve into what this rating entails:

First Digit (6): The first digit in an IP68 rating pertains to solid particle protection, specifically dust and other particulates. A "6" rating means the device is completely dust-tight, preventing any dust particles from entering under specified test conditions.

Second Digit (8): The second digit in an IP68 rating refers to liquid protection, particularly against water. An "8" rating indicates that the device is designed for continuous underwater immersion beyond 1 meter. The exact depth and duration of immersion can vary according to the manufacturer's specifications, but devices with an IP68 rating are generally capable of enduring immersion at several meters deep for an extended period.

Devices with an IP68 rating are widely available for various applications, including smartphones, smartwatches, fitness trackers, action cameras, and some industrial equipment. These devices are engineered to endure accidental spills, rain, or even being submerged during activities like swimming or snorkeling.

It's crucial to understand that an IP68 rating, while indicating full waterproof capabilities, does not render a device indestructible. Factors such as water pressure, temperature, and the device's condition can impact its performance when submerged. Moreover, prolonged exposure to water or exceeding the manufacturer's specified limits can damage the device's integrity and result in water damage.

In conclusion, the IP68 rating is the benchmark for devices that require comprehensive waterproofing. Whether you're seeking a smartphone for underwater exploration or a robust device for outdoor adventures, an IP68-rated product ensures it can handle the elements and deliver reliable performance in tough conditions.
