Is IP68 Waterproof Better than 5ATM?

When it comes to waterproofing, there are several different ratings that indicate the level of protection a device can offer. Among them, IP68 and 5ATM are two commonly encountered ratings. Both IP68 and 5ATM are used to assess the water resistance of electronic devices and wearables such as smartphones, smartwatches, fitness trackers, and more. In this article, we will delve into the details of these two ratings and discuss whether IP68 waterproofing is better than 5ATM.

Understanding IP68 Waterproof Rating

The IP (Ingress Protection) rating system is an international standard that classifies and rates the degree of protection provided by mechanical casings and electrical enclosures against intrusion, dust, accidental contact, and water. The first digit in the IP rating indicates the level of solid particle protection, while the second digit represents the level of liquid ingress protection.

In the case of IP68, the "6" indicates a complete protection against dust and other solid particles. Moreover, the "8" signifies that the device is protected against prolonged immersion in water and is capable of withstanding continuous submersion beyond 1 meter. However, it should be noted that the specific depth and duration may vary depending on the manufacturer and device.

Decoding 5ATM Waterproof Rating

The term ATM stands for "Atmospheres" and is a unit of pressure. In the context of water resistance ratings, 1ATM is roughly equivalent to atmospheric pressure at sea level (approximately 10 meters of static pressure). Therefore, 5ATM means the device can withstand pressures equivalent to being submerged under 50 meters of water.

A device with a 5ATM rating is typically considered suitable for swimming, showering, and other water-related activities. It provides adequate protection against splashes, rain, accidental spills, and even brief submersion, but it may not be suitable for scuba diving or activities involving high-pressure water jets.

Which Is Better: IP68 or 5ATM?

When comparing IP68 and 5ATM waterproof ratings, it's important to remember that these ratings focus on different aspects of water resistance. IP68 primarily assesses the device's ability to withstand prolonged immersion, while 5ATM measures its capacity to endure higher pressures associated with water activities.

For everyday use, both IP68 and 5ATM ratings offer adequate protection against common water encounters. Unless you have specific requirements such as professional diving or extreme water sports, either rating should suffice.

Ultimately, choosing between IP68 and 5ATM boils down to personal preference, the intended use of the device, and the level of water exposure it will encounter. It is always recommended to check the manufacturer's guidelines and specifications to ensure that your device meets your desired level of water resistance.
