Which is better: IP68 or 5ATM?

In the world of technology, water resistance has become an increasingly important feature in many electronic devices, particularly smartwatches and smartphones. Consumers are often faced with two common certifications when it comes to assessing the water resistance of these devices: IP68 and 5ATM. In this article, we will examine the differences between IP68 and 5ATM, and determine which certification reigns supreme.

The IP68 Certification

The IP68 certification is a standard set by the International Electrotechnical Commission (IEC) that determines the level of ingress protection provided by a device against solid objects and liquids. The "IP" stands for "Ingress Protection," while the number "68" indicates the level of protection against dust and water.

A device that carries the IP68 certification offers complete protection against foreign objects like dust and sand, and is deemed fit for continuous immersion in water under specific conditions. To obtain this certification, a device must be tested and proved to be dust-tight (designated with the first digit '6') and capable of functioning normally even after being submerged in up to 1.5 meters (about 5 feet) of fresh water for up to 30 minutes (designated with the second digit '8').

The 5ATM Certification

The 5ATM certification, on the other hand, is a rating primarily used in the watch industry to determine water resistance. The "ATM" stands for "atmosphere," and the number "5" represents the level of pressure the device can withstand. 1ATM is approximately equal to the air pressure at sea level.

A device carrying the 5ATM certification is deemed suitable for everyday activities such as showering, swimming, or snorkeling, up to a depth of 50 meters (about 164 feet). However, it is important to note that this certification does not guarantee protection against activities such as diving or high-pressure water jets.

Which is Better?

In comparing the IP68 and 5ATM certifications, it is crucial to consider the specific requirements and demands of the intended use. If you are someone who enjoys recreational swimming or engaging in water-related activities like snorkeling, a device with the 5ATM certification should be sufficient for your needs. However, if you require more comprehensive water resistance, such as for professional diving or exposure to high-pressure water jets, a device with the IP68 certification is the better choice.

It is important to note that while both certifications provide a level of protection against water, they do not guarantee complete immersion under all conditions. Factors such as temperature, water composition, and sudden movements can affect the water resistance of a device, regardless of its certification.

In conclusion, both IP68 and 5ATM certifications offer varying degrees of water resistance, catering to different needs and preferences. It is essential for consumers to carefully assess their requirements before making a purchase decision. Whether it's an IP68 certified device offering complete dust and water protection or a 5ATM certified device suitable for everyday water activities, there is a certification available to meet every individual's needs.
