Is IP68 waterproof better than 5ATM

Waterproofing is an essential feature for many electronic devices, especially those designed to be used in outdoor or water-related activities. Two common standards used to measure the waterproof capabilities of these devices are IP68 and 5ATM. In this article, we will delve into the technical details of these two standards and compare their effectiveness in protecting electronic devices from water damage.

Understanding IP68

The IP (Ingress Protection) rating system classifies and rates the degree of protection provided by a device against intrusion by solids and liquids, including water. The first digit in the IP rating represents the level of protection against solids, while the second digit represents the level of protection against liquids.

IP68 is the highest level of liquid protection defined by the International Electrotechnical Commission (IEC). A device with an IP68 rating is considered dust-tight, meaning it is protected against the ingress of dust or dirt. Additionally, it is capable of continuous immersion in water beyond 1 meter depth for a specified period, without any adverse effect on its functionality.

Exploring 5ATM

The ATM (atmospheres) rating is another common standard used to measure water resistance, primarily in the context of watches. It indicates the amount of pressure that a device can withstand when submerged in water. One atmosphere is equivalent to the air pressure at sea level.

A device with a 5ATM rating is capable of withstanding pressures equivalent to being 50 meters underwater. This means it is suitable for swimming, snorkeling, and other surface-based water activities, but not for deep diving or high-velocity water sports.

The Comparison

While both IP68 and 5ATM ratings indicate a certain degree of water resistance, there are notable differences in their definitions and applications. IP68 focuses on overall liquid protection, including continuous immersion, while 5ATM is primarily concerned with water pressure resistance.

For instance, an IP68-rated smartwatch can be worn while swimming, snorkeling, or even showering without any worries about water damage. In contrast, a 5ATM-rated smartwatch should not be submerged beyond 50 meters, limiting its usage during deep-water activities.

It's important to note that neither rating guarantees absolute protection against water damage in all situations. Factors such as temperature, water quality, impact, and wear and tear can also affect the device's waterproof performance.

In conclusion, the choice between IP68 and 5ATM depends on the specific needs and preferences of the individual. If one requires a device capable of surviving in harsh environments with prolonged water immersion, then IP68 is the better option. However, for surface-based water activities, a 5ATM rating is sufficient. Ultimately, it is advisable to consider the intended usage and carefully review the specifications provided by the manufacturer before making a decision.
