When it comes to electronic devices, particularly smartwatches and smartphones, water resistance is a crucial factor to consider. Two terms that often come up in discussions about water resistance are 5ATM and IP68. While both standards aim to provide a measure of a device’s ability to withstand water and dust, they differ significantly in their testing methods, certification processes, and the level of protection they offer. In this article, we will delve into the world of 5ATM and IP68, exploring what each standard entails, how they are tested, and which one provides better protection against the elements.
Understanding 5ATM
5ATM is a rating that indicates a device can withstand water pressure at a depth of 50 meters. The term “ATM” stands for atmospheres, which is a unit of pressure. One atmosphere is equivalent to the pressure at sea level, so 5ATM means the device can handle pressure five times that of the atmospheric pressure at sea level. This rating is commonly used for watches and other devices that are designed to be worn or used in wet conditions.
How 5ATM is Tested
To achieve a 5ATM rating, a device must undergo a series of tests designed to simulate the conditions it would face at a depth of 50 meters. These tests typically involve submerging the device in water and applying pressure to ensure that it can withstand the forces exerted by the surrounding water. The testing process is rigorous and involves several stages, including:
Static pressure testing, where the device is subjected to a constant pressure equivalent to 50 meters of water depth.
Dynamic pressure testing, which simulates the movement of the device through water, such as when a person is swimming.
Temperature testing, to ensure the device can function correctly in cold or warm water.
Limitations of 5ATM
While a 5ATM rating provides a good level of protection against water, it is not foolproof. One of the main limitations of 5ATM is that it does not account for other factors that can affect a device’s water resistance, such as dust, sand, or extreme temperatures. Additionally, the testing process for 5ATM is not as comprehensive as that for IP68, which can make it more difficult to compare the two ratings directly.
Understanding IP68
IP68 is a rating that indicates a device can withstand being submerged in water beyond 1 meter, with the exact depth specified by the manufacturer. The “IP” stands for Ingress Protection, which refers to the device’s ability to prevent the ingress of solid particles and water. The “6” in IP68 indicates that the device has a high level of protection against dust and other solid particles, while the “8” indicates that it can withstand being submerged in water.
How IP68 is Tested
To achieve an IP68 rating, a device must undergo a series of tests designed to simulate the conditions it would face in a variety of environments. These tests include:
Dust testing, where the device is exposed to a controlled amount of dust to ensure that it does not enter the device.
Water testing, where the device is submerged in water to a depth specified by the manufacturer, typically beyond 1 meter.
Temperature testing, to ensure the device can function correctly in extreme temperatures.
Advantages of IP68
IP68 offers several advantages over 5ATM, including a more comprehensive testing process that takes into account a wider range of factors that can affect a device’s water resistance. Additionally, IP68 provides a clearer indication of the device’s capabilities, as the exact depth and conditions under which it was tested are specified by the manufacturer.
Comparison of 5ATM and IP68
When comparing 5ATM and IP68, it is clear that both ratings have their strengths and weaknesses. 5ATM provides a good level of protection against water, but its testing process is not as comprehensive as that for IP68. On the other hand, IP68 offers a more detailed and specific indication of a device’s capabilities, but it may not provide the same level of protection against extreme pressures.
Key Differences
Some key differences between 5ATM and IP68 include:
The testing process: 5ATM involves a series of tests designed to simulate the conditions at a depth of 50 meters, while IP68 involves a more comprehensive series of tests that take into account a wider range of factors.
The level of protection: 5ATM provides a good level of protection against water, but IP68 offers a more detailed and specific indication of a device’s capabilities.

Conclusion
In conclusion, both 5ATM and IP68 are important ratings that indicate a device’s level of water resistance. While 5ATM provides a good level of protection against water, IP68 offers a more comprehensive and detailed indication of a device’s capabilities. Ultimately, the choice between 5ATM and IP68 will depend on the specific needs and requirements of the user. If you need a device that can withstand extreme pressures and conditions, IP68 may be the better choice. However, if you are looking for a device that provides a good level of protection against water at a more affordable price, 5ATM may be the way to go.

What is the difference between 5ATM and IP68 water resistance ratings?
The 5ATM and IP68 water resistance ratings are two distinct measures used to evaluate the ability of a device to withstand water and dust. The 5ATM rating is a measure of water pressure, indicating that a device can withstand a water pressure equivalent to a depth of 50 meters. This rating is commonly used for watches and other devices that are designed to be submerged in water. On the other hand, the IP68 rating is a measure of both water and dust resistance, with the “6” indicating that the device is completely dust-tight and the “8” indicating that it can withstand being submerged in water beyond 1 meter.
In terms of real-world applications, the 5ATM rating is often considered sufficient for devices that are intended for use in water, such as swimming or snorkeling. However, the IP68 rating provides an additional layer of protection against dust and other environmental factors, making it a more comprehensive measure of a device’s overall durability. When choosing between devices with 5ATM and IP68 ratings, it’s essential to consider the specific use case and the level of protection required. For example, if you plan to use your device in harsh outdoor environments, the IP68 rating may be a better choice, while the 5ATM rating may be sufficient for casual water use.
How do manufacturers test devices for 5ATM and IP68 water resistance?
Manufacturers use a variety of tests to evaluate the water resistance of devices, depending on the specific rating being targeted. For 5ATM devices, manufacturers typically subject the device to a pressure test, where it is exposed to a water pressure equivalent to a depth of 50 meters. This test is designed to simulate the conditions that a device would experience during swimming or snorkeling. For IP68 devices, manufacturers use a combination of tests, including dust ingress testing and water submersion testing. The dust ingress test involves exposing the device to a controlled environment with dust particles, while the water submersion test involves submerging the device in water to a depth of at least 1 meter.
The testing process for 5ATM and IP68 devices is rigorous and involves multiple stages. First, the device is prepared for testing by sealing any openings or ports that could allow water or dust to enter. Next, the device is subjected to the relevant test conditions, such as water pressure or dust exposure. Finally, the device is inspected for any signs of water or dust ingress, and its functionality is verified to ensure that it is still operating correctly. By using these tests, manufacturers can ensure that their devices meet the required water resistance standards and provide reliable performance in a variety of environments.
Can devices with 5ATM or IP68 ratings be used for deep-sea diving?
Devices with 5ATM or IP68 ratings are not necessarily suitable for deep-sea diving. While these ratings indicate that a device can withstand some level of water pressure, they are not equivalent to the specialized equipment used by professional divers. The 5ATM rating, for example, is equivalent to a depth of 50 meters, which is relatively shallow compared to the depths that professional divers often reach. Similarly, the IP68 rating is designed for devices that are intended for use in shallow water, such as swimming pools or bathtubs.
For deep-sea diving, specialized equipment is required that can withstand the extreme water pressures found at great depths. This equipment is typically rated for much higher pressures than 5ATM or IP68 devices and is designed specifically for use in diving applications. If you plan to use your device for deep-sea diving, it’s essential to choose a device that is specifically designed for this purpose and has been tested and certified for use at the relevant depths. Using a device with a 5ATM or IP68 rating for deep-sea diving could result in damage to the device or even pose a risk to the diver’s safety.
Do 5ATM and IP68 ratings guarantee that a device is completely waterproof?
The 5ATM and IP68 ratings do not guarantee that a device is completely waterproof. While these ratings indicate that a device can withstand some level of water exposure, they are not a guarantee against water ingress under all circumstances. For example, the 5ATM rating is based on a static water pressure test, which may not reflect the dynamic conditions found in real-world use. Similarly, the IP68 rating is based on a test that involves submerging the device in water to a depth of at least 1 meter, but it does not account for other factors that could affect water resistance, such as temperature or water pressure changes.
In addition, devices with 5ATM or IP68 ratings can still be vulnerable to water ingress under certain conditions, such as if the device is exposed to water at high pressure or for an extended period. Furthermore, the ratings do not account for other factors that could affect a device’s water resistance, such as the presence of scratches or other damage to the device’s exterior. To ensure that a device remains waterproof, it’s essential to follow the manufacturer’s guidelines for use and maintenance, and to avoid exposing the device to conditions that could compromise its water resistance.
Can devices with 5ATM or IP68 ratings be used in saltwater or chlorinated water?
Devices with 5ATM or IP68 ratings can be used in saltwater or chlorinated water, but with some caveats. The 5ATM rating is based on a test that uses freshwater, and the IP68 rating is based on a test that uses water with a specific level of salinity. However, saltwater and chlorinated water can be more corrosive than freshwater, which could affect the device’s water resistance over time. Additionally, the presence of salt or chlorine could compromise the device’s seals or other components, reducing its water resistance.
To use a device with a 5ATM or IP68 rating in saltwater or chlorinated water, it’s essential to follow the manufacturer’s guidelines and take some precautions. For example, you should rinse the device with freshwater after use and avoid exposing it to high concentrations of salt or chlorine. You should also avoid using the device in water with high temperatures or high pressures, as these conditions could compromise its water resistance. By following these guidelines and taking the necessary precautions, you can help ensure that your device remains waterproof and functional in a variety of aquatic environments.
How do 5ATM and IP68 ratings affect the overall durability of a device?
The 5ATM and IP68 ratings can have a significant impact on the overall durability of a device.
