Is IP68 Waterproof Better than 5 ATM?

In recent years, the demand for waterproof devices has significantly increased due to the rise of outdoor activities and the need for durability in everyday gadgets. Two of the most commonly mentioned waterproof ratings are IP68 and 5 ATM. In this article, we will delve into the technical aspects of these ratings to understand which one offers better water resistance.

Understanding IP68 Waterproof Rating

The IP (Ingress Protection) rating is an international standard that defines the level of protection provided by a device against solids and liquids. The first digit in the IP rating refers to solid particle protection, while the second digit indicates the liquid ingress protection.

IP68 is currently the highest level of protection against both solid particles and liquids. The number "6" denotes that the device is completely dustproof, making it impervious to any solid particle. The second digit, "8," signifies that the device provides protection against continuous immersion in water beyond 1 meter under specified conditions. However, it does not specify the depth or time duration of the submersion.

Exploring 5 ATM Water Resistance

ATM stands for atmospheres and is a unit of pressure measurement commonly used in watchmaking. One atmosphere is equivalent to the average air pressure at sea level, which is about 10 meters of water column pressure. Therefore, a watch or device with a 5 ATM rating should theoretically withstand pressures equivalent to being submerged in water up to 50 meters deep.

It's important to note that the 5 ATM rating does not indicate the device's ability to endure prolonged snorkeling or diving activities. While it can handle accidental splashes or short-term water exposure, it may not be suitable for underwater sports or frequent deep-water immersion.

Which One is Better?

Comparing the IP68 and 5 ATM ratings, it's clear that IP68 offers a higher level of protection against water and dust than 5 ATM. With an IP68-rated device, you can confidently take it for swimming, showering, and even snorkeling without worrying about water damage or any particles entering the device.

On the other hand, while a 5 ATM-rated device provides good protection against accidental splashes and rain, it may not be able to withstand extended exposure to water or high-pressure activities. It is important to consider your specific needs and use cases when choosing between these two ratings.

In conclusion, if you are someone who frequently engages in water-related activities or wants maximum protection against water and dust, an IP68-rated device would be the better choice. However, if you mainly need basic water resistance for everyday situations, a device with a 5 ATM rating may suffice.

Ultimately, understanding the technical aspects behind the waterproof ratings allows you to make an informed decision based on your requirements and ensure that your devices are adequately protected.
